I'm the original creator of Ghostty. It's been a few years now! I don't know why this is on the front page of HN again but let me give some meaningful updates across the board.

First, libghostty is _way more exciting_ nowadays. It is already backing more than a dozen terminal projects that are free and commercial: https://github.com/Uzaaft/awesome-libghostty I think this is the real future of Ghostty and I've said this since my first public talk on Ghostty in 2023: the real goal is a diverse ecosystem of terminal emulators that aim to solve specific terminal usage but all based on a shared, stable, feature-rich, high performant core. It's happening! More details what libghostty is here: https://mitchellh.com/writing/libghostty-is-coming

I suspect by the middle of 2027, the number of people using Ghostty via libghostty will dwarf the number of users that actually use the Ghostty GUI. This is a win on all sides, because more libghostty usage leads to more stable Ghostty GUI too (since Ghostty itself is... of course... a libghostty consumer). We've already had many bugs fixed sourced by libghostty embedders.

On the GUI front Ghostty the apps are still getting lots of new features and are highly used. Ghostty the macOS app gets around one million downloads per week (I have no data on Linux because I don't produce builds). I'm sure a lot of that is automated but it's still a big number. I have no telemetry in Ghostty to give more detailed notes. I have some data from big 3rd party TUI apps with telemetry that show Ghostty as their biggest user base but that is skewed towards people consuming newer TUIs tend to use newer terminals. The point is: lots of people use it, its proven in the real world, and we're continuing to improve it big time.

Ghostty 1.3 is around the corner, literally a week or two away, and will bring some critically important features like search (cmd+f), scrollbars, and dozens more. In addition to GUI features it ships some big improvements to VT functionality, as always.

Organizationally, Ghostty is now backed by a non-profit organization: https://mitchellh.com/writing/ghostty-non-profit And just this past week we signed our first 4 contributor contracts to pay contributors real money! Our finances are all completely public and transparent online. This is to show the commitment I have to making Ghostty non-commercial and non-reliant on me (the second part over time).

That's a 10,000 foot overview of what's going on. Exciting times in Ghostty land. :) Happy to answer any big questions.

Mitchell,

What has it been like witnessing terminal emulators make such a huge comeback with the advent of Claude Code et. all? I remember comments here in the early days of Ghostty along the lines of "Why is he working on a terminal emulator? We need people working on future problems, not the past!" Pretty funny considering I regularly hear people say they are in the terminal more than the browser now. Crazy times!

Overall I would describe it as "amusing."

If you told me 3 years ago that terminal usage would _increase_ I would've laughed. Beyond that, I'm now having regular conversations with the frontier agentic coding companies (since they're far and away the largest terminal users at the moment) and if you had told me 2 years ago that that would be happening because of a terminal, I would've laughed even harder.

So, it's amazing. But overall, its amusing.

Would a terminal deal with them have added another billion to your account if it hadn’t been nonprofit?

Wait, really? So I’ve used the terminal for everything for decades, and now, because of vibe coding, all The Kids have joined me? I don’t even know how to feel about that. Better terminals are nice though.

Right? It’s been kind of funny watching everyone “rediscover” the terminal and I’m over here feeling like a true graybeard “silly kids, I’ve been here the whole time.”

What’s old is new again is apparently just as true in tech as it is in fashion.

I think terminal workflows are intimidating for a lot of people, because the discoverability is lower than GUIs. You can't necessarily intuit how a CLI works, you have to read the documentation or watch a tutorial, which my 10 years in the IT industry has taught me a big barrier even for really experienced SWEs. The new coding TUIs are a more gentle introduction to that.

Yeah it’s been amusing to see people rediscovering tmux as well

I remember the first time I heard a girl use the word "lol" (early 2000s) and thought to myself: Normies have hit the internet.

I've used a terminal as my main interface FOREVER, and I'm amazed that people are joining this healthy habit of interacting with the computer as CREATORS.

Vibe coding is the first thing I’ve seen that has normies using the terminal

/* Claude Code is the strongest case of the return to the mainframe: a closed, bespoke, paid service that nothing locally run compares to. Terminals are just a natural part of the mainframe world! */

Once he fixes the past he will have more time to fix the future

He was on a podcast recently where he talked about that a little. It’s on Youtube.

What's it been like managing a fairly large project with Zig? I know you've spoken highly of the language in the past, but recently it seems like Zig has been through some substantial changes that would be relevant to a terminal emulator. I'm curious how painful the churn has been for project maintainers.

It's been extremely good. I should really blog about it in more detail because I do get asked this question regularly. It's been very good.

The large language changes are a burden, but it's something I knew going into it. And so far in every case, it's been well worth it. For example, 0.15 introduced the std.Io.Writer overhaul, but I really love the new API. I haven't started the std.Io change yet for 0.16. We'll see. And honestly, LLMs make this all way less painful... even though they're not trained on it, agents are able to run builds, reference docs, and work their way through the upgrade with huge success.

I thought that finding contributors would be an issue, but it hasn't at all. There's a lot of people out there eager to use Zig, the language isn't hard to learn (as long as you're already familiar with systems concepts), etc. It has been good.

I'll think about more to say if I write about this more but overall, I'm very happy with the language, the community, and the leadership. All good.

That's super interesting to hear. I see people say all the time "oh I would never use it in a big project because it's changing so fast", but then see awesome projects like Ghostty and Tiger Beatle written in it, so clearly they're doing something right.

I'm surprised to hear LLMs have been helpful. What little I tried to use them for with Zig, all the information was way too out of date. But I was mainly just doing research, not running an agent at the time, so that's probably why.

Yes, LLMs with Zig are absolutely useless without agentic behaviors. Throw an agent in the mix and it's totally fine. Bonus points if you pair it with some basic agent skills so it knows how to look up language references, stdlib files, etc. then it does even better.

Do you get frustrated in using a low training data language like zig with AI models? I've noticed that models tend to be better with languages like TypeScript than Swift because of issues like that.

Not at all. Give it tools and skills and it figures it out very quickly. Must be an agent. Don't use chat.

I'm the author of Trolley[0] (Electron for TUIs).

It was so easy to get the terminal functionality going with `libghostty`. Most time was spent building the functionality around it.

Thanks for making it.

I'm not quite understanding your project. What is the use case? Is this so I can package up an existing terminal app as a dedicated desktop app?

If so that actually sounds really cool. I'd like a dedicated lazygit app in my tray at all times.

Yes, that's it. It came about after writing a small TUI for a friend to back up their Vimeo library. They liked the simplicity and speed but not having to use the shell. Didn't want to install Ghostty either.

So here we are

My brother has built a game using python on the CLI and I've been trying to find a way to package it. Your project seems very promising for my use case.

Project mentions Windows compiles but isn't tested. Do you have a gut check on what issues there might be?

I think it may actually work. It's just that I only have a VM to test it on, and it does not support OpenGL. I got it to compile and run, but it crashed on that VM limitation.

Feel free to open issues in the repo, I'll find a way to get a Windows machine if there's interest.

You can also email me at `trolley [at] wands [dot] is`

This is kinda cool. Thanks for sharing.

Coincidentally I was just listening to your interview with The Pragmatic Engineer [1] this morning. Loved hearing the stories of early days at HashiCorp, taking it public, and the near-miss with VMware.

It also got me wondering how things would be different if you haven't crossed paths with the guy who unplugged your mouse :) It's fascinating how life is full of these small yet defining moments. We don't always appreciate them right away, but beautiful to look back.

Thanks for Ghostty! It has been my daily terminal driver for the past year.

I was also just recommended this interview on youtube. honestly it makes sense if the algo decided it was the right time to recommend this video and resultantly this post is making it's way to front page of HN

I subscribe to the channel, so I had already downloaded the episode. But glad PE is getting some algorithm-love; it's a great channel/podcast. Gergely is a great interviewer.

Thanks for all the work you do! I had used terminal just a few dozen times before November — and now i am in terminal more than any app (even more than the web browser).

It’s common for me to have 15-25 different terminal windows open for using Claude code. I shifted to Ghostty because I was looking for more features.

Unfortunately, none of the features I wanted are available anywhere (though I’ve come to appreciate Ghostty anyway). Here’s what I had wanted:

1. Basic text editing features (ie click to place cursor in the text input field; highlight to delete)

2. Change colors or fonts mid session (to make it easier to find particular windows)

3. Window management and search (eg, a way to find my windows when I lose them and to otherwise control them)

Apparently, it is really hard to develop features like these for terminal emulators. I’d love to understand why…

The next release includes a way to use a command palette to search for and jump between surfaces (windows, panes), which sounds like it partially addresses your third point. I had a small hand in it, by building the initial UI for the Linux version.

IMO this isn’t the job of the emulator. You can do this all in `tmux` for example.

As for editing text, ghostty+tmux most definitely supports editing text with the mouse (even an in terminal right click menu!) although sounds like your intended use of select to delete isn’t common so you’ll need to do some customizations.

What makes you say that isn't the job the emulator? Sure it is. In fact, tmux itself is a terminal emulator that you just so happen to run inside of another terminal emulator that you want to multiplex.

I’ve been using scroll back search for 15+ years with Terminal.app and iTerm2, and there’s no way that’s not the job of the terminal. You don’t know how good that is until you use it.

For 1, take a look at https://github.com/alex-903/zsh-mouse-and-flex-search. It runs as a zle-line-init hook, so it works in any terminal. A full terminal app implementation would be cleaner, however.

Now that Ghostty is part of a real org, is there any way people can sponsor specific features/bugfixes? I've been waiting for drag/drop to be working on KDE before I make the switch, and I'd be happy to pay for a fix.

> the real goal is a diverse ecosystem of terminal emulators that aim to solve specific terminal usage but all based on a shared, stable, feature-rich, high performant core. It's happening!

I recall the package manager war of Haskell between "stack" and "cabal-install":

Users would have strong opinion depending on their background.

But the developers eventually made both projects use the same libraries.

Both tools allow for ghcup to manage the compiler, so there's no conflict there.

The difference is eventually just a frontend experience, and all the heavy lifting and synergy is achieved behind the scenes.

I would not have believed the same is possible for terminals, even cross-platform, so thank you for having this vision.

Do you think there's entry barrier, even if pride based or psychological, to the fact that libghostty is called so rather that something more generic?

Let's say I'm the creator of Alacritty, would I have more problems adding libghostty than it's generically named identical counterpart libtermengine?

I'm not concerned with it.

The real goal isn't for Alacrity or Kitty or WezTerm or any other terminal to use libghostty. I think over the long term, terminal emulator user bases dwindle down to niche (but important) use cases.

The real goal is for higher-level tooling (GUI or browser) that utilizes terminal-like programs to have something like libghostty to reach for. I think this represents the much, much larger ecosystem out there that likely touches many more people. For example, Neovim's terminal mode, terminal multiplexers, PaaS build systems, agentic tooling, etc. You're seeing this emerge in force already with the awesome-libghostty repo.

libghostty would still be useful for traditional terminal emulators to replatform on, and for example xterm.js is seriously looking into it (and I'm happy to help and even offered their maintainer a maintainer spot on libghostty). But, they're not the goal. And if fragile egos hold people back, it's really not my problem, it's theirs.

Thank you for you answer, I had misunderstood the main objective of where it was meant to be applied, this makes sense!

As an outsider to the fascinating world of terminal emulators... can you explain why this might be? Rather, what about `libghostty` would be off-putting vs `libtermengine`?

Just that it's a specific "product"-y sounding name? Would you also be concerned about "libwayland" vs "libcompositor"? Genuinely curious: this seems like an insightful question, I just don't follow the reasoning.

Disclaimer: I am not the maintainer of anything terminal related, it's just an intuition.

Let's say I'm the creator of ghostty "competition".

The fact that is has the same name, could feel if I change that:

- Maybe my users start thinking why don't I use ghostty instead - Will the maintainers of libghostty chose more oriented to ghostty than for my terminal?

It's a half assed analogy, but think if Google's V8 would be called ChromeEngine instead of V8.

Many thanks for everything. Without Ghostty I wouldn't have been able to create https://github.com/rcarmo/webterm and have a decent browser-based terminal that works the way I expect it to.

Having incorporated libghostty into my current web-based project, I can't say enough thanks. I've lived in the terminal since 2003, resisting IDEs, VSCode, everything because I'm a die hard Vim + tmux guy. Vibe coding coming back to the terminal, and being able to use libghostty to facilitate that is a serious vindication of my steadfast resistance to move away from the terminal.

I'm sure you feel the same watching Ghostty become what it has. Big thank you.

mitchellh: What is the current thinking WRT adding client/server functionality (like built-in tmux+mosh)? I recall you talking about it on the Changelog podcast, and that would be a killer feature for me; I really make a lot of use of the wezterm equivalent, it's so nice having first-class UI windows rather than tmux's faking of it.

Zellij has been holding me over with tabs and panes (in quick terminal) while I wait for them to come to ghostty directly.

Tabs (and panes? I haven't tried yet) should work fine for regular terminal windows though.

There's a PR out there for tabs in quick terminal https://github.com/ghostty-org/ghostty/pull/9857

Did a double take on this one since my Ghostty has had panes for a while now (I run tip/nightly). Didn't realize it's not part of the current release.

Also, Zellij is nice.

Just to clarify, it's more about the ability to run a terminal on my Linux box and connect and disconnect to it from my Mac that I'm looking for. Wezterm does a good job of this. Previously I was using tmux and mosh and Nebula, and that worked really great for reconnecting (I almost never had to reconnect, it just stayed live, wezterm I need to reconnect all the time, but that works reliably). But copy-paste with tmux is meh.

You're one of the forefront experts in terminal protocol parsing. Do you have opinions on "interceptor" applications like tmux or mosh, for example? These applications technically need to do extra upfront work (especially mosh as it transforms the entire protocol) and it's not a transparent "I treat vt100 as a black box, I put bytes in, I get well structured, standardized events out". Does libghostty-vt support that currently, does it intend to support these kinds of protocols in the feature, or is this kind of thing outside the scope of the project?

Can you please add an rss feed to your blog? Thanks for the amazing work

https://mitchellh.com/feed.xml

thanks!

Random advice question. My brother taught himself to program and has been making a terminal-based game. What started out small has turned into a highly polished game with ascii art, sound, you name it.

I’ve been trying to figure out how I could actually help him distribute it and I keep coming back to the best option being to wrap his programs terminal output into a host process that can emulate and render it. It seems that the lib Ghostty might be perfect for the former, but not quite yet on the latter?

I don't have specific references for you, but perhaps you could look into how old-school roguelikes packaged their software for distribution. Particularly ones that made the jump to Steam or Itch?

Maybe as an SSH app? See https://snakes.run for a recent example.

somehwere else in this thread this project was mentioned (uses libghostty): https://github.com/weedonandscott/trolley

that might be a viable approach for you

Never heard of this, thank you!

I started using it a few days ago and then I need to find something in the terminal. But....there is no find! Why? Can you guys add it? This is such a basic and critical feature that I may have to just go back to...just about anything else.

find is provided by the OS, not a terminal emulator like Ghostty. Most likely something is wrong with your paths.

I think they mean like CTRL+F kind of find.

This is addressed in paragraph 5 of the post they replied to.

Do you know of any Qt based libghostty front-ends? Also, hows zig for a relatively complex project like this? I like zig in theory but have always been worried about using it since it's still pretty early days

I literally discovered Ghostty yesterday when googling "best terminal macos" and surfaced a ~year-old reddit thread recommending it [0]. Just needed something other than Terminal so I could Cmd-Tab between distinct command-line work (e.g. claude code and ipython tabs). Was nice to find something that just worked

[0] https://www.reddit.com/r/macapps/comments/1loiw2z/comment/n0...

Fwiw x the program alt-tab on Mac gives macOS a more sane alt-tab behavior.

Cmd+` is also a useful shortcut for switching between windows of the same application

Hey Mitchell, thanks for ghostty (happy user here for a month or two). Is there anywhere I can look to see the status of the next planned release?

I've been waiting for the vim feature to hit stable, and have just been checking to see if there's a new release every so often, but I couldn't find a discussion or anything to see when it was planned.

Nvm. Had another look, and I think I found it? Is it this: https://github.com/ghostty-org/ghostty/milestone/7

I use Ghostty as my main TUI at work and absolutely love it. Most of my day lives in terminals, and Ghostty just feels fast, clean, and out of the way in the best possible sense.

I was a long-time Kitty user, but switching to Ghostty has been a big upgrade for my workflow. Hard to go back now. Thank you

Genuine question: what are the ghostty features that make it a big upgrade coming from Kitty?

Seconding that question!

What's the current state of the art with using libghostty in a browser? There are a few community projects around that compile it down to wasm.

Essentially, I have a few features that have a TUI-first UI, and the obvious next step is to expose some of that to a browser.

Excited to see the further development of libghostty! It is an exciting project in this new world of being able to develop your own agentic development environments rather effortlessly. These things are possible because of projects like yours. Thank you!

Thanks for creating Ghostty! Is there a chance to have shorter release cycles? I switched to nightly because of the mem bug and search, but ideally would like to be on a more stable channel.

I just wanted to say "thank you". I switched to Ghostty over a year ago and it's been working out great. It's now my default terminal. My favorite features are responsiveness and ease of splitting panes.

Hi Mitchell, thanks for creating Ghostty. Been part of my workflow ever since I found it. Just a small question, when do you see Ghostty can fully replicate iTerm2 popular features like output copy/selection?

Is there any chance of a stable release that fixes the memory leak issue? I know I could run nightly but for something I spend all day every day using I'd much rather run a stable version.

New stable release in 1 to 2 weeks.

Fantastic thankyou.

Congrats on creating and helming such a cool project!

Out of curiosity, does ghostty do the Quake terminal thing - I use yakuake for this, but it feels a bit long in the tooth.

It does. See https://ghostty.org/docs/config/keybind/reference#toggle_qui...

This works on MacOS, and on Linux sometimes:

> On Linux, the quick terminal is only supported on Wayland and not X11, and only on Wayland compositors that support the wlr-layer-shell-v1 protocol. In practice, this means that only GNOME users would not be able to use this feature.

I use it on MacOS, but it doesn't support tabs.

I came to Ghostty for the icon, but stayed because of the experience, the philosophy and your dedication and enthusiasm. Thanks!

Thanks for your awesome work. Never thought I’d switch to a terminal without cmd-f, but ghostty made it worth it. Can’t wait for v1.3!

Cmd+F ! Thank goodness!

can you please make a Windows version!!

bro please update ur support for not gtk DE please

> front page

Nice! Looks like I should have rushed the interview. :D

Hi,

Big fan. Can I get a ride on your jet?

Recently tried multiple terminals because I am gradually migrating off of Macs and I liked Ghostty but the lack of searching the scrollback has turned me away from it. Opening another editor to do the same I tried but didn't like.

WezTerm has everything I need and is closest to iTerm2, minus being able to quit it and have it restore all windows and tabs on restart -- but oh well, it's not an important enough feature. It also renders my prompt perfectly; no small pixel divergences like all other terminals have.

Kitty I don't remember why I rejected.

Alacritty I like but the lack of tabs is not acceptable for the moment... and before you ask: I hate tmux. So much more key presses to achieve basic functionality, it boggles my mind why people love it. But, to each their own obviously.

It's also likely I'll settle for some Linux-exclusive terminal but as I'm not yet possessing a Linux workstation (just a laptop) I haven't put the requisite time to do this research.

Suggestions are welcome.

> Kitty I don't remember why I rejected.

Maybe worth another look at then? I'm far from a Kitty power user, but it does pretty much everything else I want it to, including working as a quake-style terminal[0]. And you can extend it with kittens[1] if you so desire. Also, the next release should presumably include smooth scrolling[2] which I'm quite looking forward to.

Maybe more than any one feature though, I appreciate the hard work that Kovid (the creator of Kitty) has done to tastefully add new VT standards and try to make terminals as useful as they can be in the 21st century.

Kitty is the best one. It has several features which have proven so useful I wasn't able to stay on anything else for more than a couple of hours (including the one this topic is about).

Ctrl+Shift+G wraps the output of the previous command into a pager (say, less). You often only know you needed a pager after that output is printed.

Ctrl+Shift+E highlights all links on the current screen and assigns short alphanumeric codes to them, so you can open links without using the mouse. For example, `Ctrl+Shift+E 1` opens the first link, `.. 2` the second one, etc.

Ctrl+Shift+U opens symbol search where you can find & insert symbols using their unicode names. Emoji, TUI blocks, rare accented characters you need once in a blue moon, CJK ideographs, whatever.

These small quality-of-life features make a big difference. In my terminal (TerminalNexus, Windows) I added per-tab session colors - click a palette icon, pick a color, and the terminal background and tab header change for that session. Simple but it's saved me from running commands in the wrong environment more than once.

Kitty is great, but its author has very strong opinions, strongly held; this keeps a number of popular requests summarily rejected. In particular, there is no way to color plain bold text, which is possible in basically any other emulator. This is a deal-breaker for me personally, it makes reading e.g. man pages unnecessarily hard.

WezTerm is a very good replacement.

> author has very strong opinions.

So true. To the point I have to maintain my own fork to make the command key my meta

Out of curiosity, what is the reason given to not color plain bold text ?

I'm not the GP, but I do remember why I rejected Kitty when I tried several terminal emulators last years: it broke quite a few of my workflows.

For instance, in vim the F3 key was broken[^1]. It was very surprising and weird, and a portable workaround required some arcane vim configuration.

Another important pain point was that the font rendering was different in Kitty to any other app, and very dependent on the screen DPI. IIRC, for a DPI around 100, I had to switch to "legacy rendering" because the default rendering was barely readable.

I also remember issues with SSH. And Kitty crashed at least once. And I wasn't a fan of Kitty's mix of C and Python. After a week or two of usage, my Kitty config file was big, with an extra hundred lines of Python for the tabbar. Despite some nice features (like the shortcut to put the output of the last command into a file), I got uneasy with all this mess. I tried Ghostty, which was as good as Kitty with much less oddities.

[^1]: https://github.com/vim/vim/issues/13328

Kitty is the GOAT terminal

I wouldn't say I love tmux, but I have a configuration file that I put on every computer I use regularly that is very comfortable for me. I basically live in the terminal across many different machines, and having the same interface for managing panes and tabs even when using ssh is invaluable.

I also use vim (well neovim) as my primary editor, and have set up tmux to integrate well with it, so that might contribute to my appreciation and continued usage of it.

If you spend any amount of time on remote machines with unreliable connections, local tmux is insta-reject because tmux inside tmux is very inconvenient. As with GP, it's also why I don't consider terminal emulators without tabs at all.

> because tmux inside tmux is very inconvenient.

Hitting c-b c-b isn't that inconvenient?

Agreed.

I hold Control and double-tap b for managing the remote session, then everything else is the same.

Granted, I'm not a power user, so there may be numbers that get frustrating. I could imagine complex splits getting confusing (I don't use splits at all).

C-b is less ergonomic than C-a that is the default on GNU screen. The first thing in tmux is to remap to C-a. (Triply so if you remap caps lock to ctrl.)

I switched to zellij, but I made more like my tmux was because I didn't want to learn new binding; C-q activates tmux mode. C-q + g locks so I can pass through comamnds to inner zellij. C-g unlocks. on super+enter for it opens a ghostty it and atached it to zellij session named $(hostname).

On reboot it remembers my tabs and panels and even commands that ran inside last (i.e there is popup in every panel that had something runing to run it again or just open a terminal)

Before my great wayland migration I ran patched st and it was great. Terminal job is render what terminal multi-plexer gives it and passes input to multiplexer.

I went with C-a for quite a long time, but then I discovered that C-a is a keymap for jumping the cursor to the beginning and f the line, so I remapped tmux prefix to C-Space.

Yep, I've been using tmux for almost 10 years. Its config has followed me across every terminal I've used in Windows with WSL 2, macOS (work laptop) and native Linux. It's a nice abstraction over getting split panes, windows (tabs), sessions, search, scroll back, consistent key binds and the overall theme to work the same across environments.

Yep same, I install ohmytmux and I'm ready to go.

Foot is worth a look. It’s the only terminal I’ve ever seen that starts up in sub-50ms cold, without a service already running.

But you do have to run a proper window manager so you don’t have to require tab support in every single app. ;)

What proper window manager shows tab group list at the top of the current app window and allows shortcuts/mouse to reorder the list and also allows moving a tab outside of this list to another tab group?

Sway and i3. But when a WM does it, you can mix different apps in the same tab group, and your tab key binds can be the same as your WM key binds. You don’t have to remember alt+h for tabs, win+h for windows, etc.

But I’m just busting your chops, don’t listen to me. I don’t even use i3/Sway, or use tabs at all. Everyone has their own workflow that works best for them.

Scrollback does exist on Ghostty! But you need to switch to “tip”. This can be done in the config file. The tip build is very stable and has many bugs fixed (like various memory leaks).

Tip is good but depending on your platform you might need to build it yourself and then you need a particular zig version.

Does it work all the time? I'm using tip and had scrollback stop working after a long ssh session.

there's scrollback search in the nightly build if that's an option for you (I've been using it a ton for a few months and haven't seen any bugs so far):

https://github.com/ghostty-org/ghostty/releases/tag/tip

I haven't seen anyone else mention Terminology yet. It uses an unconventional GUI framework (Enlightenment / EFL), but that aside, it's fast and has more or less all of the features you'd expect of a terminal:

https://github.com/borisfaure/terminology

Its "moment" as a new novel terminal was over a decade ago, but it still chugs on working just fine. Notably(?), gregkh uses it (or used to use it):

https://www.linuxfoundation.org/blog/blog/greg-kroah-hartman...

Back in 2018 I thought it felt kind of sluggish and consumed quite a bit of resources, but looked pretty. Have they improved on performance since then?

Are you sure you're thinking of the same terminal? Its standout feature has been performance. Granted, that was 10+ years ago, but I've never noticed it regressing.

Yeah, I'm sure, used it for work on a Ubuntu box over the summer 2018, didn't bring it with me home.

You can search scroll back on Ghostty nightly. I switched straight from iTerm2 (after 20 years of iTerm), but _do_ remember the reason I rejected Kitty: it has a ton of Python in it, which is usually indicative of software which is going to be a pain in the ass.

> Alacritty I like but the lack of tabs is not acceptable for the moment... and before you ask: I hate tmux.

Another option is to leave the tabbing to your window manager.

Cool, but I'm 100% clueless as to how. Haven't migrated to Linux yet and this one of the next important items for me to learn.

I like tmux because it does more than tabs in an emulator. I can detach from a session on a remote host to leave a process running after I disconnect, or to pick the session back up on another PC.

I do use tabs rather than repeatedly switching tmux sessions, but I do end up running tmux for splitting the GUI into side by side layouts.

Detaching is working just fine with `screen` as well.

I like the idea of tmux but as another poster suggested, I prefer to just get better at my window manager to achieve similar results. tmux requires way too many key presses for me.

> Alacritty I like but the lack of tabs is not acceptable for the moment... and before you ask: I hate tmux.

Surprised none of the other commenters have mentioned zellij. I work across windows (WSL) and linux so really like having the same set up for both, which means no Ghostty/Kitty since they don't support windows.

Zellij is a lot smoother and nicer looking out the box, and its key shortcuts are pretty intuitive. There's a lit of advantages to not having an extra layer, but zellij + alacritty is definitely worth having in your list of options!

https://zellij.dev/

Scroll back search is coming. You can try it in the nightly.

Very glad for that--it's what made me stop my evaluation the first time around. I looked for the feature in issues and just saw #9821 about memory use of the buffer which could be an issue if configuring very large scrollback as I do.

BTW is there feature parity between macOS and Linux, e.g. scrollback buffer searching on Linux?

I'll wait for the stable release and will retest it. Not in a rush and not the early adopter kind of guy.

Give it "a week or two"

SecureCRT is a paid program I’ve used for years and it’s just so comprehensive. It’s not cheap but the quality shows.

I built a Windows terminal emulator (TerminalNexus) and scrollback search was one of the first things I prioritized. Ctrl+F opens a search dialog with regex and case sensitivity, and the buffer size is configurable per shell profile. No tmux needed.

Personally kitty is the only one I keep coming back too. Mostly because it's very customisable, fast, lean, ligatures, separate font for italics, great macro support, and supports automatic tiling panes.

> Alacritty I like but the lack of tabs is not acceptable for the moment... and before you ask: I hate tmux. So much more key presses to achieve basic functionality, it boggles my mind why people love it. But, to each their own obviously.

Tabs usually mean mouse+click to switch which takes way more effort that a simple alt+number or similar keybinding used to switch "tabs" in tmux. I'd guess that some terminal emulator tabs allow keybindings to switch tabs as well but, modelling OP, I'm focusing on the expected default experience.

No, zero mouse usage, you can both address each tab by number and just moving between them. I wouldn't have any terminal emulator without the latter feature at least, and all I've tried support it.

I hate mixed mouse + keyboard workflows as well.

Just like zero mouse and same single keypress tabs w/ tmux... my point was that this is not a distinguishing characteristic of terminal tabs.

Been a long time since I last tried tmux but was not switching between panes something like Ctrl-B + Ctrl-<something_else>? I don't remember but if it was that it's still much more than Super-Left/Right.

Kitty has poor security

https://github.com/kovidgoyal/kitty/issues/2084

That's a bold claim not backed up by your source.

You can turn on a feature documented as allowing the terminal to be controlled by escape sequences, but then output of programs can control the terminal! Whoop-de-do.

These look like the major past threads (in reverse order) - have I missed any?

I love Ghostty, especially the UI is so much nicer than Kitty. However, for some reason ghostty sometimes has severe issues with dealing with SSH connections. The terminal is like broken and wrongly displayed and you can't properly type something. Therefore, I still use Kitty, especially for SSH connections. I don't know what `kitten ssh` does, but it makes my terminal work with SSH.

This is what kills it for me. Half the time I'm using a terminal I'm sshing and the fact that I need to copy over term-info on virtually every machine keeps me from using it more often. Even copying term-info doesn't always fix it. From what I've read it's not entirely ghostty's fault but as a user it's frustrating.

Have you seen the `ssh-terminfo` option for shell integration? https://ghostty.org/docs/config/reference#shell-integration-...

No I haven't seen that before. I used to just run the terminfo tic command that's recommended in the top searches and when that started failing I just swapped back to default terminal for SSH

you can always export TERM=xterm or some other value if that's causing you grief while distros catch up.

Same. On the tip of main, at least, I can open the command palette and choose reset to bring it back to life. I set a keybinding for reset to skip the command palette.

> I love Ghostty, especially the UI is so much nicer than Kitty.

What are you talking about? What UI does Kitty have?

He probably refers to the fact that Ghostty aims to use the native window decorations etc.. So for example on Ubuntu it uses gtk, on mac the native macOS tab bar etc. Same goes for the scrollbar and search window.

I really like this a lot.

Big one are the tabs. Kitty has tabs, but rendered in the text rows, so it's missing features that the native OS tabs provide (drag and drop, easy to move around and split into windows...)

The fetishization of tools is one of the things that mark a dilettante mindset.

You see it on all hobbies, e.g. when the someone sees a photograph and their first question is about what camera and optics were used. No question about composition, light, the moment, creativity... they only care for the tools.

The technique and knowledge is the important thing, not the tools. They forget the good practitioner can do a great photo with a $200 phone than they with the best Canon DSLR.

I have seen this in all hobbies I have practiced, be it musical instruments, kolinsky brushes on miniature painting, montain bikers, running apparell...

As I'm getting older I care less about editors, terminals, Linux distros... and after seeing what can be done with agentic coding tools less so.

I have no idea why I am responding to someone who flippantly uses a phrase like "dilittante mindset", but here we go

there is definitely a tendency for noobs and amateurs in any hobby or industry to obsess over expensive gear and things that don't matter (I love the term "buyhard" for it). you're out of your mind if you think the professionals in literally any industry do not discuss the specific technical tradeoffs of tools they are using among themselves.

I don't feel like this is a fair argument because different tools help different workflows. Since there is always a continuous growth of new people learning new things, it would make sense that tools change over time. Especially in a realm that is digital, not physical.

FWIW once I found my workflow (vim + tmux) I stopped caring so much about chasing "new" tools. Now have the luxury to wait 3-5 years and see what's worth adopting, most of it isn't only because I already found a workflow that works for me; but if you're new or still finding what works best, you'll always be experimenting.

Yes, and one of my favorite anecdotes like this: at one of the greatest jazz concert ever recorded, Charlie Parker played a cheap plastic saxophone because he hadn't brought his own.

https://jazzfuel.com/charlie-parker-the-plastic-saxophone-th...

It is cringe to buy niche gear and learn obscure in-group terminology because you are trying to short-cut through enjoying the hobby itself directly to enjoying the status and acceptance that non-hobbyists enjoy.

But "fake it until you make it" is part of life too and everyone wants to belong and to be taken seriously. You can't always just "do the hobby for fun" if you want to be social since anxious intermediates whose own output is still crap will gate-keep.

If you can, find hobbies that bring you joy and do them alone, free from the influence of too much right and wrong, at least in the first stages.

In the context of terminal emulators, idk, do something like learn AWK purely for personal enjoyment. You may not have the flashiest dotfiles or color schemes or whatever, but you'll be able to do arcane stuff in the terminal that will give you confidence you belong and others will be amazed by.

This is a very weird take. For people who spend their entire day in the terminal, having the right terminal is incredibly important. Like saying track athletes shouldn't spend money on running shoes if they own a pair of slippers.

Can relate well. In my early days I used to jump around linux distros and editors and terminals too, but with time as I have converged down to actually working a tech job.. Windows 10 LTSC and VSCode (with its inbuilt terminal) have become my staples.

This is not about it being a hobby, ghostty is the sanest terminal emulator currently available for MacOS where you can just install and start using it. Customising your terminal doesn't need to be your hobby anymore.

Composition, lighting and creativity are no more than tools either.

Some people fetishize tool curation over results. But also, the true high-efficiency creators prioritize their tools over everything. To be truly efficient and to get in the flow, you need tools that work with your particular style and approach. This is why there are lots of idiosyncratic tools and opinions about tools out there. Since not everyone works the same way or has the same preferences, there’s a natural market for unique tools that work differently to suit all those people. The “religious wars” over editors are really just people missing the point and arguing for no reason. Emacs is better for some people. Vim for others. Vscode for others. Notepad++ for others. Nano for others. This is a good thing.

If you don’t care about your craft or workflow enough to care about what tools you use, I wonder what level of quality you can achieve.

I agree to an extent that tools are not important.

But, for me, there is a certain threshold that a tool must pass to be useful. A tool that is below this level is only slowing you down or limiting your abilities.

You wouldn't use a knife to tighten screws if you have a perfectly good screwdriver lying around. And there's little to no advantage of buying a new expensive or over-engineered screwdriver.

I believe, plain vi is the lowest I can go for writing code. That doesn't mean that I can't use notepad or nano, but they fall under the level of being useful and only cripple and slow me down.

Ghostty passes this level of usability for me, but personally I'm fine with st - no gpu, no cpu spikes, uses barely any ram and still feels snappier. So, what's the point?

From one old man to another it's tough when you lose that spark.

When Ghostty was publicly announced, I used it for a few months and gave up on it due to the lack of support for the CMD+F feature that I use Terminal.app. This is a critical feature for me while tailing logs on my local. I tried the workaround of capturing the text into a text file and then searching it. It just didn't work for my workflow and dropped it. Ghostty is great otherwise. But, without the CMD+F, it's of no use to me.

The tip releases have had search support for a few months:

https://github.com/ghostty-org/ghostty/issues/189

https://x.com/mitchellh/status/1993728538344906978

As Mitchell stated above:

> Ghostty 1.3 is around the corner, literally a week or two away, and will bring some critically important features like search (cmd+f), scrollbars, and dozens more. In addition to GUI features it ships some big improvements to VT functionality, as always.

Same. Lack of search and lack of scrollbars make me wonder why this project got so much attention in the first place. iTerm2 seems way more capable.

I suspect it is "just" the very nice-looking default theme in Ghostty. I updated my iTerm2 colors with colors I picked from Tailwind‘s excellent color palette and iterm2 now feels fresh and has all the features I want.

Mitchell’s attempts at more correctness and better speed, plus the no-nonsense UX. iTerm2 is confusing and overwhelming and bloated for those of us who just want a terminal that works.

Sounds like that’s coming in the next release per Mitchell’s comments above, fwiw.

For anyone using this terminal that hates != (and others) being turned into a single character, I have the following to turn off ligatures:

    font-feature = -dlig
    font-feature = -liga
    font-feature = -calt

This can be updated in `$HOME/.config/ghostty/config`.

Note in Ghostty 1.3 we disable discretionary ligatures (I think dlig/calt) by default as recommended by font standards. We still enable liga though that usually contains far less controversial ligatures.

Maybe only dlig was disabled? On tip I had to add `font-feature=-calt` to disable ligatures like != for Berkeley Mono v2.

Or maybe you can solve it like I did -- by using a font that does the (IMHO) right thing with regards to ligatures

https://github.com/0xType/0xProto#4-ligatures-that-dont-defo...

I can't recommend 0xProto enough, the only thing I'm sorry about is that I didn't find it sooner :)

Going to give this one a try; I'm still partial to Atkinson hyper legible, but this one looks fun.

My only issue with ghostty is it isn’t immediately recognized by some programs through ssh (eg less) and they don’t operate properly. However there’s a one liner that solves the problem permanently on the remote machine[0] so it isn’t too bad. Hopefully in the near future ghostty’s terminfo will be shipped with common linux distros.

[0] https://ghostty.org/docs/help/terminfo

I find this docs page fairly hilarious. Complaining about how the rest of the world is in the stone ages, and that is why ghostty doesn’t work with it.

For me, a terminal program that requires me to muck with every machine I log into to get it to work is pretty horrible. I connect to a lot of different machines every work dat. Often they’re not machines I maintain. Making that harder is exactly the opposite of what I want from a key tool like a terminal program.

All of those terminals work for you now because someone went and added terminfo to ncurses which distributed it across all versions of linux.

Kitty needed to do it too back in 2018.

https://lists.gnu.org/archive/html/bug-ncurses/2018-09/msg00...

Note: Ghostty follows the same pattern as Kitty where they a) use their own terminfo, b) distribute it when ssh'ing (it gets pushed to the remote server) and c) added it to ncurses so that it will eventually go away.

Apparently changing $TERM from `screen-256color` to `tmux-256color` in tmux to try and get italics working in nvim totally mangled ghostty.

I looked into infocmp and other tricks to try and and figure out why the backspace key was throwing gibberish around, but I had no interest in debugging such an inscrutable thing through so many layers.

I don't fault ghostty for things like this, but at the same time it's hard not to scorn the tools you want to be invisible, even if making unreasonable demands of them on accident.

I haven't used ghostty but terminal having issues with ssh sounds like a major oversight.

I like the look of this terminal, but it doesn't work correctly with SSH (top, ncdu for example) unless you hack the $TERM variable. It feels a bit vibecoded even though it isn't.

To give a little productive criticism, one thing I really miss is when having tiled terminals, I want to be able to full screen one of them temporarily. Double click in iterm allows this, so does mod+f in i3wm. It really is the only thing stopping me from switching to this (and I admit it might be buried somewhere in the settings)

> To give a little productive criticism, one thing I really miss is when having tiled terminals, I want to be able to full screen one of them temporarily.

I think you're looking for the `toggle_split_zoom` binding which has existed since Ghostty 1.0 and is default bound to `cmd+shift+enter` on macOS which is the same binding as iTerm. It's also visible in the menu and command palette.

We recently added a kind of split title bar, making it double click to zoom is a good idea. I'll add an issue for that to the roadmap.

Can I take advantage of you being here and express some desiderata?

1. The quick terminal feature is ghostty's killer feature for me, I switched to ghostty because of it. Could we make it first-class feature? Like, i'd love to have tabs over there too (like in guake/yakuake).

2. I have a white on black theme (white text on black background) but when i split vertically/horizontally, the borders between one shell and the next are not really visible and I have an hard time resizing them... Can you do something about it? Setting the colors of borders would be an okay fix for me.

I could have sworn I checked every menu option but it is there, thank you

also, from not that long time ago, you can change the focus of panes and you can tell it to respect the zoom state if you want, which is super convenient

Using its own TERM is a deliberate design decision. I don't remember how to fix the terminal database, but it's pretty easy (your favorite search engine or LLM should be able to help you there).

Or the manual, which describes the features for automatically handling it.

https://ghostty.org/docs/help/terminfo#ssh

I definitely have had to poke at things a bit, even where they "should" work. I use salt in my homelab and eventually got the xterm-ghostty.terminfo file and I put it in my baseline salt config, then you run 'tic -x xterm-ghostty.terminfo'.

i had to do this for ssh

host * SetEnv TERM=xterm-256color

I don't know enough about these things to know why, but I have pretty much always had to hack $TERM to get things working smoothly with any remotely featureful terminal emulator. I have occasionally needed similar hacks for Kitty and urxvt, for example (though top and ncdu seem to work fine).

The way terminal applications handle different terminal emulators on Linux just seems to be a bit broken. I don't think it's a particular indictment of Ghostty or any one emulator.

I just checked Kitty and top fails on Debian 12, so I think I was unfair in just calling out Ghostty for this

I wish TERM would contain a list of terminal types in decreasing order of specificity, like 'ghostty:xterm-256color', so a system that doesn't know what ghostty is would fall back to xterm-256color, but that ship has sailed long ago.

You can in theory set TERMINFO with the terminfo definition, and you could skip faffing with terminfo files but it isn't passed or accepted by openssh by default.

I've personally given up on using the various "modern" terminals, they end up missing too many features (and then try to claim xterm compatibility), and especially if you use devices outside the standard linux systems (e.g. old/embedded hardware, switches), they have too many rendering issues.

I have tried every possible setting but SSH ends up breaking more often than not. As opposed to iTerm which just works.

Same here. I have a Ghostty often open but end up using iTerm2 for pretty much everything. It's not just having to hack the TERM (which I ended up doing), it's that sometimes something about the TERM internally breaks anyway and I'm back to seeing ESC codes when I press an arrow. Quit & restart fixes it but it's just enough friction to keep me away.

It sounds like you simply forgot to update your terminfo on your remote system.

You must do this if your chosen terminal requires settings that are not compatible with "xterm-256color".

Alacritty, kitty, and wezterm also require this, as they implement features that xterm doesn't (and most likely never will), if your terminfo DB is too old to already include them.

Using Alacritty as an example, you'd take a file that looks like this, https://github.com/alacritty/alacritty/blob/master/extra/ala... , and run `tic -x -o "~/.terminfo" "that.info"` on it.

Its been this way for like 30 years, and it'll never change.

If you have to configure the host to support the client rather than the client supporting unknown existing hosts, then what you have is a terminal, not a terminal emulator.

In 1970 all terminals were their own thing, tied to a single host somewhere in the same building by a dedicated serial cable. The terminal didn't move or connect to random other hosts, and the host had to be specially configured to work with any terminal connected to it.

Since then, a few terminal definitions have become standardized across all hosts for decades, and terminals are emulators that emulate one of those 40 year established standard definitions, because today terminals connect to countless unknown new random and varied hosts that the terminal user didn't install and configure before connecting, and may not even have the admin rights to do so after the fact either, and even if they do, it's wildly and inexcusably awful to require that.

It's entirely backwards for a terminal today to default to asserting it's own new $TERM, and to characterize the problems caused by this as "the user forgot to do this totally unreasonable thing" that no other terminal or terminal emulator has required for 40 years.

It's 100% a bug. The fact that it's intentional just means it's a design goal bug.

It might be a bug in remote handling and I might have unfairly called out GhostTTY for this, but "forgetting to update terminfo on my remote system" just doesn't hold with the way I work.

I work managing different systems for different clients and often login to systems for the first time. The servers aren't mine, and configuring something like Ansible to configure my home just seems like a waste of time for little benefit. It means that generally I end up using systems that are likely to be already instead - Bash not zsh, Perl, basic vim without any bindings. It might sound special but I'm sure I'm far from the only person working this way.

So given this, I'd always prefer a terminal that doesn't require me to change remote servers. In this particular case I can modify $TERM in my local .zshrc and it works fine so it's a moot point, but if I had to modify the remote system it would be a no go.

Bit of a shameless plug, but for those looking to configure Ghostty using an actual GUI, you can use this web tool I've been maintaining since the original closed beta of Ghostty https://github.com/zerebos/ghostty-config

Thank you for dropping this link. I opened ghostty for the first same, then when preferences dropped me into a TUI editor with no syntax highlighting I closed it and reopened iTerm.

I liked the idea of a fast new terminal, but not enough to RTFM before figuring out if it was worth switching.

I enjoy it, and it’s great to have another modern high performance terminal as an option for macOS and Linux.

For me, Kitty still has the edge:

https://sw.kovidgoyal.net/kitty/

WezTerm is also a strong contender:

https://wezterm.org/

When I tried Wezterm last year, you couldn't select more than 3-5 lines of text. I went to fix the 'bug', I found that it was intentional because it allocates a string and copies multiple times every time you click and drag.

Even if that's fixed, that design put me off the terminal forever.

Been using/abusing wezterm for years, my scrollback is set to 1000000 and text selection has never been a problem... copy mode however does make it even easier

I regularly select hundreds of lines in Wezterm. I have never had a problem.

Wezterms is certainly nice. I guess they haven't release another update? Currently stick to iTerm2.

I switched from iTerm2 because at the time (possibly still), iTerm2 had a performance bug where large amounts of underlined text would cause the terminal to slow down noticeably. Wezterm works perfectly, and I appreciate the .lua configuration over iTerm2's mess of menus.

How's the latency? I've had to keep using xterm even though it kind of sucks just because it's got the lowest latency by quite a bit.

According to this (at least 11 months old) benchmark, Ghostty has the worst input latency across all contenders: https://github.com/moktavizen/terminal-benchmark?tab=readme-...

More benchmarks from 4 months ago: https://news.ycombinator.com/item?id=45253927

14 months old discussion of input latency in Ghostty with comments from the author: https://github.com/ghostty-org/ghostty/discussions/4837

I have been using computers and terminal for a long time, and this kind of comment makes me think I must have missed a whole bunch of things which can be done with a terminal

Since people are mentioning latency I’ll mention throughput. Basically the idea is that you accidentally cat a large file to your terminal and we are measuring how much time it takes for the terminal to finish displaying it. This test generally favors GPU-accelerated terminals.

Ghostty performs very well on this regard, among the same league as Alacritty and Ptyxis.

It feels amazing on linux. I find it very noticably better than konsole.

Foot/Alacritty also feel amazing but they don't have some features of Ghostty.

My benchmark is opening neovim and scrolling with the mousewheel so not sure how represantative that is though

Have you tried kitty with more aggressive settings? It feels very responsive out of the box, but the defaults are balanced for sane energy use on portable machines.

  repaint_delay 5
  input_delay 1
  sync_to_monitor no

on my machine, noticeable. I seriously tried it, but went back because I could notice a small end-end latency, between keypress and action. But I'm also 240hz user.

Ghostty is fast and feels native, but WezTerm occupies a different niche: it's a terminal you program rather than configure.

The Lua config isn't just "dynamic" in the abstract sense. I built a tmuxinator-style workspace manager that spawns project-specific layouts - named tabs, splits, working directories, startup commands - from a fuzzy launcher. Session state auto-saves every 10 minutes with timestamped snapshots and crash recovery. Theme toggling between dark and light mode triggers a system-wide theme switch script. These are runtime behaviors, not static settings - try doing any of that in TOML.

The built-in multiplexer is the other major differentiator. Splits, directional navigation, pane zoom, pane selection with alphabet overlays, moving panes between tabs or windows, all without a tmux prefix key. It's not just "WezTerm has splits too, it's that the interaction model is fundamentally more fluid when there's no mode switching.

WezTerm isn't trying to be the fastest terminal. It's trying to be the most programmable one, and for people who want their terminal to work as a development environment rather than a PTY renderer, that tradeoff is worth it.

I have a terminal manager project[0] I'm currently using xterm for, but very curious to try libghostty. Have mainly been hesitant because it hasn't been promoted from an internal ghostty dependency (only awareness of the place was from this article by the creator[1]), but from the sounds of it here people are finding it stable enough. Gonna give it a whirl today.

[0]: https://github.com/ouijit/ouijit [1]: https://mitchellh.com/writing/libghostty-is-coming

Tried Ghostty several times and I really appreciate the font rendering, but I keep going back to iTerm2 and Terminal.app mostly because of lack of scroll back & CMD-F, etc. Looking forward to what is coming in the next release.

I've been following this before it was made public and I'm a big Zig fan so I would definitely switch to this, but I've tried and failed many times. Currently it just keeps crashing multiple times (on three different machines) each day on my mac and the quick terminal doesn't support full screen mode (it still shows the menu bar). I could live with the menu bar showing, but because of the constant crashing I'll wait for a bit and check back in a few months.

It’s a shame that version 1.2.x got abandoned and didn’t receive any important bug fixes. That has severely cut my trust into this project. It’s been over 4 months since the last 1.2.3 release, so the memory leak when using Claude is not addressed, my Ghostty crashes are not addressed (crash reporter doesn’t work), I don’t even bother looking at the issues anymore, as I know I am not getting the fixes for a long time.

And I’m not running a critical piece of productivity software on a nightlies channel!

I'm not doubting your personal experience, but I find the crashes you mentioned surprising; I have never once, since v1.0.1, had Ghostty crash. Tbf I use it with tmux, so I'm not exercising some of its capabilities. But with tmux, I have at any given time 5-7 sessions, each with 2-5 windows, some with panes.

you should try foot terminal, i have been using for the past couple of months and it is quite good

Ghostty's terminfo entry doesn't enable 24-bit color*, and as far as I can tell they don't provide a "ghostty-direct" entry that does. It just seemed odd that it's completely supported and working, yet not easily enabled. Maybe I just missed a trick, and didn't need to make a custom terminfo entry myself?

* "msgcat --color=test" is an easy test that shows the blending of 24-bit color, or blocky gradients otherwise.

Loving how well Ghostty works and looks. When running several Projects I need quite a few tabs as all these AI agents take sometime to complete. Overhead tabs get real messy very quickly. Multiple windows become a nightmare quickly. Side bar tabs have been my solution.

I love iTerms sidebar tabs - I add emojis to mine for my key projects and any subtask just lives under the master tab like a folder.

Would love to see sidebar tabs - or it sounds like I can code my own.

Ghostty with sidebars and more https://github.com/manaflow-ai/cmux

While I quite liked Ghostty to being with, the lack of a scripting API quickly drove me to WezTerm before long. See: https://github.com/ghostty-org/ghostty/discussions/2353

I hope they prioritize scriptability soon. It's quite important to my personal git worktree ergonomics.

i hope they implement something that can be used with tmux -CC mode.

If there wasn't kitty I'd definitely be using Ghostty, but I have no reason to switch.

I haven't tried Ghostty yet, but for a windows user the combo:

wt.exe https://apps.microsoft.com/detail/9n0dx20hk701?hl=en-US&gl=U...

pwsh.exe https://learn.microsoft.com/en-us/powershell/scripting/insta...

is really powerful, it has finally driven me away from conemu, which was really bad with claude (lots of fonts problems).

Feature request: renaming tabs! Helps keep tabs organized instead of 20 tabs with similar names. (See Zed for example)

Also! I'm considering Ghostty web (https://github.com/coder/ghostty-web) for my project Ink Web. It's awesome that Ghostty can work in the browser to replace xterm.js.

https://github.com/cjroth/ink-web/pull/1

Project: https://www.ink-web.dev/

I've used Ghostty in the past, but nowadays it's hard to use it since you have to take in count that running agents requires using tmux sessions which is something Ghostty does not support very well

Why is it in the main page? It's a super well-known project no?

Because someone thought it was interesting, and enough other people upvoted it.

It’s been posted many times, I think mostly due to it’s association to Mitchell Hashimoto. It’s left as an exercise the reader to determine why this is important.

Looking at the comments it seems like there are still people not using it

Just because you know about it doesn’t mean others can’t benefit from the mention.

https://xkcd.com/1053/

Does ghostty support single duplex ? I couldn’t find out.

Also, does it support visible control characters ? EXACT EMULATION ? 3270 ? VT-105 ? VT-220 ? VT-320 ? VT-420 ? SIXEL ? NAPLPS ?

What kind of features am I missing if I just use GNOME Terminal?

The biggest boon is that it's a development target for making TUIs etc. App developers get the most benefit out of it.

Funny, I was just configuring ghostty. I finally made the jump in order to get rid of tmux as a layer of indirection.

Here's what I landed on: This config tries to emulate as much of tmux with native ghostty features (splits and tabs).

https://codeberg.org/jfkimmes/dotfiles/src/branch/master/gho...

Add https://zmx.sh into the mix for detach/attach functionality. It uses libghostty for rehydrating session state and scrollback

Curious to hear some more recommendations, I settled on using lxterminal which works well enough. I couldn't get wezterm to recognize fonts on ALpine no matter what I did, kitty doesn't support tabs and ghosttty sounds like it has issues with ssh connections? I feel like I tried most at some point but if anyone has suggestions for a tabbed terminal emulator nicer than lxterminal, ideally with transparency, I'd love to hear them.

As a counterpoint to Ghostty ssh. I have literally never had an issue and I manage a large cluster of boxes that run everything from centos 7 to rocky 10. All from ghostty on a Mac.

I've never quite understood why terminal emulators nowadays have GPU acceleration. They've not been slow for a long time. What am I missing?

If you compare them side by side, you actually can see how slow some of them are. The way I compare is to open them all up tiled on my display joined to the same tmux session, then try doing heavy redraw operations, like maybe cmatrix. You can clearly see how some of them are quick at redrawing, and some are not.

Some people do not care about the difference, but it is definitely there.

I've commented on this before. Sign of the times. People like anything related to GPUs. In my personal coding projects I've even been tempted to ask the agent: "What features can I add that use the GPU?"

Bigger than ghostty is libghostty which enables things like: https://www.cmux.dev/

I tried it when it last had an HN post (a week ago?) and found it to be very buggy and went straight back to Ghostty.

Very happy after a few days switching from ghostty to cmux

Serious question here, not trolling.

Ghostty looks great; obviously a lot of hard work went into it.

My question is why? I am seriously curious about what motivated you to make this considering the space is already so crowded with reasonable solutions.

I see this kind of almost duplication of effort a lot, and I am really interested in what motivates people to undertake these kind of projects.

Why do you need a new search engine called Google when you have Yahoo Search, Ask Jeeves etc.

People do it because they care about some X factor, maybe they dont like that most existing terminals are slow and they want to build a better product.

Still curious

We often see Ghostty on the front page. What makes this project special? Is it solving a big problem with current terminal apps?

In my experience it actually is. I went through multiple terminals and they all had issues for me (missing key remapping functionality, slowness, not working across platforms, UI ugly...), but Ghostty is solving most of these.

Can't use it yet because I need cmd-f find.

It's a nice terminal but it cannot be configured to the same level as iTerm, e.g. in terms of colors, look and feel, how the menus work, how the tabs work, etc.

Also, in practice, I find it hard to detect any performance difference between iTerm and Ghostty even though I know in theory that Ghostty is more performant...

So for now I go with iTerm because I prefer the UI.

I used to use the iTerm programmable notification bell which would ring when a particular output was printed in the terminal. Don't think I can do that in Ghostty

I've only ever stuck with urxvt and more recently foot since moving to Wayland. On Mac the default terminal works for me, though I've been using Ghostty to follow a trend, but I seriously don't understand the benefits netted to me? (other than the cool icon)

I stayed with Terminal.app for quite awhile. Until very recently (not when Ghostty was released) it didn't have 24-bit colour support. It also didn't have shell integrations such as triple click to select all output of the last command. The configuration system is arse and is kind of a lock-in as it is in all plist form, so I had a hard time extracting the colours I used for my terminal and using them elsewhere.

Now that they've updated it recently, it is a better terminal, but otherwise Ghostty has a few bells and whistles that make the experience nicer.

I expected this to point to the 1.3.0 release since it’s expected in March. Hopefully we get that soon.

ghostty has extensive shader support and claude knows how to write shaders... i was tired of staring at boring black rectangles all day... so i built a shader that fills the background with slow-moving color gradients.

every window gets its own palette that drifts over an hour. i think it's beautiful without being distracting.

thank you mitchell and contributors for implementing and supporting animated shaders! thank you to the folks who have shared their shader code in public so i could build this! it was so much fun to make and i use it everywhere

stay gold, shine bright

Ghostty is awesome, ill echo the sentiment regarding lack of IPC/scripting API being my current hold back. Sticking with kitty til then. I still keep the ghostty binary on hand so I can +boo :^)

for libghostty consumers, favorite i've tried so far is neurosnap/zmx.

I can't find an alternative to Terminator, being able to drag and drop panels to create layouts is such a strong workflow that it's very hard to give up

I did give Ghostty a try, the turn off was Adwaita, the tablet UI for the tabs and context menu.. i just can't

For people that use it and have used kitty, how do you find it better? I don't want to be pedantic or anything I just want to know if I'm missing out, I installed some time ago but didn't find anything really interesting

I made a simple TUI Ghostty config manager called Ghofig. Try it out. https://github.com/intaek-h/ghofig

I keep trying it but keep coming back to alacritty on Linux and iterm2 on osx.

I tried this out after getting annoyed for the 100th time by a recent bug in kgx/console that will occasionally fail to launch windows leaving incomplete windows as tabs.

Console has long since become abandonware pushing people towards ptyxis which is now the default gnome terminal. A damn shame considering console is basically complete software (the quality of software in gnome is on a downhill).

I would have given ptyxis a chance if they didn't take a basic terminal and added some fluff (features related to distrobox) on top of other annoying things I can't be bothered to remember about because I ended up removing the software every time I gave it a spin.

In just a few days I've been able to replace console with ghostty-nightly and I don't miss anything.

What features related to distrobox? I use both ptyxis and distrobox and I don’t notice any integration between them. I do notice an integration between ptyxis and sudo however. It simply turns the title bar red.

Love the product. Have you considered implementing panes and windows that work with tmux’s CC mode? Any considerations specifically for claude code or agentic terminal users?

Why use this over iterm 2?

Ghostty is extremely performant. I had a bug in some concurrent software; when I added logging the bug would disappear because the threads acquiring the lock on STDERR was sufficient to make the bug go away. On Ghostty this happened fast enough that I was able to reproduce the bug.

Maybe I should have been writing everything to a file. ¯\_(ツ)_/¯ Anyway, I didn’t think of it at the time and Ghostty saved me.

Really nice terminal.

Unfortunately scrolling in terminal apps via mouse wheel seems to be broken (on release and main branch), which is currently a blocker for me. Hope this will be fixed soon.

I started using ghostty coz I needed different terminals for all those AI agents.

E.g. with MacOS terminal, I launch Claude, with Ghostty, I launch opencode, with Attyx I launch pi

Speaking of foot, are you going to do a client server architecture for instant terminal setup? Foot instances start up very fast due to this

The minimum-contrast feature is great, to help in those times when some color combination would have been unreadable otherwise.

I like how snappy Ghostty is. I do not like how it starts lagging after a few alt-tabs to Chrome and back on Linux.

just installed ghostty, looks cool. but my honest question is how it is significantly better than iterm2 to justify such a switch? I am aware of the fact that it is faster, uses less memory, various configurations is more straight forward. but is that all?

I have the feeling that I must be missing something big here.

I’ve been using iTerm2 for years. I’ve tried ghostty a few times and quickly went back to iterm each time for various reasons I can’t immediately recall. There is nothing I can think of lacking from iterm.

That said; if I was working more on Linux or Windows where iterm doesn’t exist it looks like ghostty would be a good option.

Same. As far as I can tell, Ghostty is still in active development and unfinished. For regular use iTerm 2 is a complete product that can be relied upon.

Damn I’m jealous that they figured out how to pay their contributors. I’ve been toiling away for free

How is it possible that this thing constantly gets so much hype? It's a terminal emulator.

Beats me. Its hype is all out of proportion to its features.

Maybe this is why the creator is touting the use of libghostty, the underlying library.

It helps a bit that it's written in Zig, but its primary differentiating feature in the sea of terminal emulators is that it's created by mitchellh, who is kind of a celebrity in some circles.

Is there a windows equivalent to what Ghostty is? Windows Terminal is really slow

This project makes me wish item were faster, because it’s way more useable.

why does everyone freak out about this terminal whenever it's posted?

> Ghostty is […] feature-rich […] uses platform-native UI

What goes through the head of a developer when writing such blatant lies in the introduction text? What does he think he accomplishes by doing so? Is he so deluded that he thinks behaviour like this is somehow socially acceptable and the readers just nod along and no one is going notice and criticise him for that? Really, it's like the mind of children in an adult body, no concept of reputational damage.

I just installed Ghostty and cannot help but conclude that the claims are wrong, abundantly so. Compare it with the incumbent Konsole. It is clear to anyone to see that Ghostty has about 0.3% of its features. If I were to enumerate everything that's missing, I would not be able to stop until tomorrow.

It suffices to point out that there is no menu bar, no icon toolbar, no l10n, no settings dialogue, no key-bindings dialogue, no scrollbar, no search, and it would go on and on and on. The sad thing is, if the developer actually used the platform-native UI like he claims, then he would instantly get the first five without lifting a finger!

How much of ghostty is written by Claude?

Mitchell Hashimoto doesn’t need LLM’s, LLM’s need Mitchell Hashimoto

On the new mac tahoe with rounded corners (which are really frustrating to me), ghostty should add small margin on the bottom, because the font is sometimes renedered on it and letters are cut (rarely but infuriating, when it happens)

Worth posting here: https://github.com/ghostty-org/ghostty/discussions

I use it but have people trier cmux?

Installed the snap on Ubuntu 24.04 and when I used it to look at /etc/sudoers.d/README, it emitted:

WARNING: terminal is not fully functional

Press RETURN to continue

...which I thought a little odd.

This is a test comment

Bro randomly decides to post a link to ghosty docs and gets 275 points

Yeah, i have been using foot so far as i found ghostty and warp terminals too much memory consuming

Submission upvotes don't count nearly as much as comment upvotes in terms of points.

Ive been using Ghostty after AI recommended it for lightweight claude sessions.

No complaints been happy using it for my claude swarms for about a month

Ghostty calls itself "feature rich" but only added cmd+F / find functionality a few months ago. Makes me wonder what other basic functions it's missing.

A config page. Reasonable padding defaults.

Probably more, but after dealing with unhelpful errors while trying to debug my config file, I figured I'd come back to ghostty another time.

I have Ghostty 1.2.3 and it STILL does not have cmd+F find.
