Ask HN: What underrated open source project deserves more recognition?

169 pointsnagstler141 comments

Are there any that you have come across that you think deserve more recognition?

Alternative to postman, that's fully local and syncs to git easily. Unlike hoppskotch and insomnia that are free, but offer paid sync, Bruno just works in git. Unlike others, it doesn't dump JSON that's hard to diff, but has its own easily diffable format. You can share your collections in your existing git, with your existing accounts and PRs.

Also has integrated CLI testing.

He plans to sell GRPC later for money. HTTP and GraphQL API works now. https://www.usebruno.com/pricing

Thanks for posting this! I did a lot of API work in Python last fall and I was just using curl because, as far as I could tell, none of the other clients (Postman, hoppskotch, insomnia etc) were fully offline.

Bruno looks fantastic and it is only $9 USD for a preorder license right now. That is a pretty good deal to support this work.

This does deserve more recognition but unfortunately we don’t talk about Bruno

Haha sick reference.

We recently stumbled upon Bruno and it's been great so far. Our team has been exploring alternatives to Postman, and Bruno's recent updates on Oauth2 made it an obvious choice. I hope that more people start using Bruno and contribute to its development.

> All open-source contributors of Bruno will receive a free license for the Golden Edition. I'm a fan of this idea. I hope we see more attempts to make open source sustainable while still keeping the product accessible like this project.

All these clients miss something I really want, Protobuf support for regular HTTP/S requests, they all pretty much have Protobuf stuff already from implementing GRPC support

What do you mean? Can you please explain more or raise a GH issue?

A regular HTTP request with protobuf as the body, load a .proto file, select a message and enter the values

isn't that just grpc?

Bruno doesn't have grpc.

I never said that it did?

But clearly they're planning to add it.

Cosmopolitan https://github.com/jart/cosmopolitan and https://justine.lol/cosmopolitan/index.html

Some genius realized that you can actually embed valid win32 programs inside valid posix shell scripts, and found a way to make a C cross-platform solution out of it, meaning that you can write C programs that compile to a single executable that will run on (quoting the site) Linux + Mac + Windows + FreeBSD + OpenBSD + NetBSD + BIOS

It all started from this post.

Missing post in previous comment, sorry. https://justine.lol/ape.html

A truly excellent project

Agreed. I'm trying to use it at https://github.com/wekan/wekanstudio . Contributions very welcome.

https://github.com/BespokeSynth/BespokeSynth

BespokeSynth takes the concept of a modular synthesizer and expands it so that the application is less just a synth and more a complete modular DAW. I've used it to create MIDI/audio workflows that I couldn't get exactly the way I wanted in Ableton or FL Studio. It also has a module for doing livecoded audio processing in Python that I'm just starting to scratch the surface of.

This has been posted a few times already, but I cannot tell you how life changing Paperless NGX is for organizing PDFs. As someone who wrangles all of the insurance and bills for my house, this open source software is so damn good.

https://docs.paperless-ngx.com/

I maintain Bash script to quickly set it up locally on Linux with Podman. Give it a spin if you want to kick the tires.

https://github.com/jdoss/ppngx

my script also has paperless-ngx included https://github.com/ei23com/diy-smart-home

pretty neat stack... I chose other projects in some cases (e.g. ntfy vs gotify) but all in all it's pretty complete. Thanks.

Did you consider watchtower to keep the dockers up to date?

thanks for the tip! Not tried watchtower yet since i just have to click an update button and a background task in "screen" will be start a docker pull of the full stack and also clean up. Also have that for the host. I don't now what watchtower is doing better, but since some project come with breaking changes i need to decide when to update... Anyway update notifications are nice to have.

Open streetmap

I'm so amazed by the amount of problems that can be solved by using this data.

Need to find out the nearest drinking water tap. They got you covered.

Need to know how you can enter a particular subway station as a blind person? The data should be there. Including traffic lights with audible feedback.

Want to charge your ebike at your destination? Find type of bicycle rack and the availability of power outlets.

Need to mail a letter? The collection time of the nearest post box is there.

Planning a trip? The access fee of an attraction is documented.

Need to find a gate at any airport. ...

I would also mention Street Complete, as the companion app to contribute all that data.

https://github.com/streetcomplete/StreetComplete

StreetComplete is fabulous, and another surveying app worth mentioning is Every Door [0] which is specifically focused on updating business and other POI details.

[0] https://every-door.app/

Quick plug for the OpenStreetMap community, too. Online or in-person, there are so many active mapping groups. I started one in my city last year and it's been an awesome way to meet with like-minded folks and feel like we're making an impact on others' lives. Check out the OSM Community Index [0], or the (multilingual) Discourse [1], or feel free to reach out to me if you want to learn more about engaging with OSM!

So i am hearing about Open street map for the first time. Can someone explain a bit more about it and how can i use it in day today life.

"OpenRefine is a powerful free, open source tool for working with messy data: cleaning it; transforming it from one format into another; and extending it with web services and external data." https://openrefine.org/

I like https://github.com/pyinfra-dev/pyinfra. "pyinfra automates infrastructure using Python"

Only played with it for a little but it seems well designed an simpler alternative to ansible, chef and other such things.

Thank you for posting this! Happy to answer any questions anyone has :)

Thank you for building it and sharing it!

I just found about this project from this comment, absolutely excited to try this out.

As someone who's never used any of the infrastructure tools, I'm thinking of pyinfra as a way to run shell commands + install dependencies on hosts (declaratively?) on a bunch of hosts via ssh.

Inventory is to sort of take a self-defined inventory on a bunch of hosts?

One final question on usage, would it be possible to sync or reference files from the machine running pyinfra on the remote hosts? Or would that have to be done indirectly via running shell commands to sync?

Missed this comment apologies!

- ops are (mostly) declarative, but some (server.shell) will always execute the command given

- inventory is just that, basically a list of hosts to target plus associated data, docs page: https://docs.pyinfra.com/en/2.x/inventory-data.html

- absolutely for syncing files, check out the files.put and files.template operations (and the files ops in general): https://docs.pyinfra.com/en/2.x/operations/files.html

I’ve used several different IaC tools; Puppet, Ansible, Terraform and Polumi to name a few.

What would you say are key differentiators of PyInfra from these existing projects?

Both Terraform and Pulumi differ slightly I think provisioning cloud resources - pyinfra can be used alongside to setup instances/etc, I’ve used the pyinfra/Terraform combo with great success.

For ansible/chef, etc the main reasons/benefits boil down to:

- instant feedback esp on errors, get the stdout/stderr of whatever command pyinfra was executing, there’s no agent or abstraction to hide it

- configure in python rather than yaml+jinja2 mess

- integrate with the whole python package ecosystem

- speed and small overhead as inventories scale

+1 on this! It's scales amazingly well too!

https://github.com/NightscoutFoundation/xDrip

xDrip+ is an unofficial and independent Android app which works as data hub and processor between many different devices.

It supports wireless connections to G4, G5, G6, G7, Medtrum A6, Libre via NFC and Bluetooth, 630G, 640G, 670G pumps, CareSens Air and Eversense CGM via companion apps. Bluetooth Glucose Meters such as the Contour Next One, AccuChek Guide, Verio Flex & Diamond Mini as well as devices like the Pendiq 2.0 Insulin Pen.

Heart-rate and step counter data is processed from Android Wear, Garmin, Fitbit and Pebble smart-watches and watch-faces for those that show glucose values and graphs.

On some Android Wear watches, it is possible for the G5 or G6 to talk directly to the watch so it can display values even when out of range of the phone.

The app contains sophisticated charting, customization and data entry features as well as a predictive simulation model.

I’ve posted this before but I love it so much I gotta do it again.

You plug in a piece of ASM from a video game ROM, and it gives you a first pass decompilation. On the left hand side you can edit this decompilation, and on the right there’s a side-by-side diff of the target ASM and what your source currently compiles to. It’s slightly gamified, looks great, is super easy to fork/share, and can be pretty addicting once you get into it. Super cool community.

I discovered these 3 amazing projects recently:

Cryptpad, essentially google docs/sheets/forms e2e encrypted. It does include collaboration. https://github.com/cryptpad/cryptpad

Immich, google photos self hostable, with share options https://github.com/immich-app/immich

Nginxproxymanager manages certificates and proxies to self hosted stuff through nginx https://github.com/NginxProxyManager/nginx-proxy-manager

Great self hosting stuff!

I've been using both Immich and Nginx Proxy Manager for a while now, it's the first time that I see Cryptpad, it looks like an awesome tool.

I recently tried the Collabora Online integration in Nextcloud, but was quite disappointed with it, the right-to-left button was greyed out for no apparent reason, and creating shapes and moving then around felt sluggish (clicking the rectangle tool directly added a rectangle in the middle of the slide, which I could then drag around and resize, but the transformation tools seemed buggy and didn't really work well).

I'll certainly try out Cryptpad

I have a bash script for self hosting (mostly docker services). https://github.com/ei23com/diy-smart-home

I can recommend traefik as proxy too

ImHex

“A Hex Editor for Reverse Engineers, Programmers and people who value their retinas when working at 3 AM.”

I actually used it not too long ago to inspect why a mp4 file wasn’t valid. The pattern language that they have is quite nice and having sections of the hex highlighted and being able to see what structures they represent and what data was on those structures was very useful!

https://github.com/WerWolv/ImHex

Can confirm. ImHex is an amazing tool for a cyber analyst because it also supports yara rulesets, so you can quickly iterate and try out whether the malware was or will be detected. And it even supports capstone to disassemble the binary, while you debug the code and edit the yara rule!

Combined with ghidra, these are pretty much the most valueable tools in my day job.

(with golang, vim, arch etc of course)

Postgraphile. Postgres + graphql. It really solves all the negative aspects of graphql. Also, incredibly performant. Their v5 release is also a pretty interesting piece of tech.

https://postgraphile.org/

Interesting, This project looks very versatile, Can experiment with quick a backend API on Postgres.

It’s one of the few big projects that still feels “open source” as opposed to corporate run open source.

I think Netflix is a big user / sponsor of the project.

I didn't see a v5 tag in order to know, and I have no idea what "utils/graphile" does for the project, but one will want to ensure they are aware of its licensing scheme https://github.com/graphile/crystal/blob/db8894c74eb0ec3fe96...

Its an optional command line utility that you may use with PostGraphile which does things like printing out your configuration in a pretty format and using TypeScript to figure out what options are available to you based on the plugins you are using. It is 100% non-essential because all the options are documented in each of the plugins (and also you can use TypeScript auto-complete in your editor), and you can just console.dir() your configuration. You can read about it here: https://postgraphile.org/postgraphile/next/config#viewing-th...

Graphile worker is also awesome. Wish celery was as good -- I've been thinking of implementing a compatible worker in Python

I played with this a bit years ago when it was still called PostgraphQL. My biggest issue with it was that there didn't seem to be a recommended (or even suggested) version control method for things like functions. Using a standard migration tool to update functions seems like hell, so I gave up on using it.

Looking through the docs, I still see no mention of version control or even migrations at all. Is this something that has been solved?

It’d be like any other database schema change. We commit all schema migrations to git and have cicd run them.

Is there any alternative that works with Python?

QCAD[1]

I Used it to create home improvement drawings. bit of a learning curve but very flexible and powerful

1 - https://www.qcad.org/

What I love about qcad is how keyboard-driven it is. Are there other cad programs that I can operate mostly by typing instead of clicking?

There's OpenSCAD, but I don't think it's exactly what you mean

https://openscad.org/

Symphytum https://github.com/giowck/symphytum

A small cross-platform personal GUI database app for desktop, with support for images. A modern riff on the idea of MS Access (for those old enough to remember). I think I saw someone claim it's a clone of some Mac app, but I'm not a Mac person so I have no idea if that's true. It's my go-to app when I want to do some shopping research/comparison and collect my results, and I'm not yet sure what fields I will need in the DB. I like it more for that purpose than a spreadsheet.

The repo is archived (unfortunately), but the binary releases work for me for now.

Judging by the screen shots Symphytum is patterned after Apple/Claris FileMaker https://en.m.wikipedia.org/wiki/FileMaker Which is one of Apple’s oldest products. (Maybe only the Macintosh itself has had a longer run, although the history is a little complicated)

For macOS/iOS there's a nice database app I use for different things called Collections https://collectionsdb.com

It's really good, I use it with Shortcuts and saves me a bunch of time on small things that I don't want to create an app for this.

Filestash [1] was born after the infamous FTP top answer on the Dropbox launch [2]. Trying to understand why we couldn't have nice things made on top of FTP, I came out with this interface:

  type IBackend interface {
    Ls(path string) ([]os.FileInfo, error)
    Cat(path string) (io.ReadCloser, error)
    Mkdir(path string) error
    Rm(path string) error
    Mv(from string, to string) error
    Save(path string, file io.Reader) error
    Touch(path string) error
  }

and once I had the UI working nice for FTP, I made it work for every possible file transfer protocol: S3, SFTP, NFS, SMB, WebDAV, Dropbox, Google Drive, .....

Phil Harvey’s exiftool [0]. Despite being a command-line tool, it is widely known and used by professional and advanced amateur photographers to extract or repair metadata in images. It does handle more than just still images.

It’s written in perl and the perl API for handling the metadata is documented, but I’ve never seen anyone use that directly.

I created an account here to say this: Exiftool doesn't only work with image files, either. I use it to extract metadata from audio files as part of a toolchain that creates playlists automatically from my music metadata.

It does lack a management GUI and that stuff is very much DIY.

I've been looking for a long time for a VPN solution that i can use without having to rely on third-party services for my home lab, and this is absolutely excellent. Sure it has no GUI but if you're already self-hosting stuff this is among the easiest thing i ever had to configure. Thanks!

Everyone hand-rolls their own dotfile management system, but YADM already does everything you need:

https://yadm.io/

I've never doubted that there are existing solutions for dot files that do everything I need, but I've yet to find one that doesn't take more work for me to swap to than continuing to just clone a git repo an symlink maybe half a dozen things the once or twice a year that I happen to set up a new machine.

You might want to have a look in stow. https://www.gnu.org/software/stow/

I just stumble across dotstow which adds a git layer on top of it https://github.com/clayrisser/dotstow

stow has worked really nicely for managing my dotfiles. Here are two blog posts that helped me get my workflow down:

https://alexpearce.me/2016/02/managing-dotfiles-with-stow/

https://bastian.rieck.me/blog/2019/dotfiles_stow/

I've looked at it before. Looking at the system I'm writing this comment on, my dotfiles from my repo are ~/.config/alacritty/alacritty.toml, ~/.config/nushell/{config.nu,env.nu}, ~/.tmux.conf, and ~/.gitconfig. I'm not sure if I just use far fewer dotfiles than average, and I know this is a matter of personal taste, but it's just not obvious to me why I'd want to add a tool to symlink five things once. Moreover, most of the jobs I've had give me a Macbook to work on rather than Linux, so that also would require me to either manually install `stow` or move getting homebrew set up to _before _setting_ up my dotfiles, which seems a bit backwards to me given that my my shell config is where I store any configuration for stuff like that.

I'm starting to wonder if I just have a very vanilla dotfile workflow compared to what some other people use. This would surprise me a bit, given how I tend to go overboard in custom configuration for most things, but it definitely feels like my experience isn't enough for me to understand why specialized tooling for dotfiles is needed.

I have a work mac, work linux, and home mac. I want the same terminal-based development environment on all of them, but each requires just a little bit of customization.

For example, the .gitconfig for work is different from home (e.g. my username/email). Ditto for my .ssh/config and my shell aliases.

I also use Nix to manage all my tools, and the home-manager configuration is slightly different between mac & linux due to platform support.

I've gone through a few iterations of home-built solutions, including extending homeshick[1], before discovering YADM which implemented everything I had done but better.

> the once or twice a year that I happen to set up a new machine

This was me for a long time - but then I started using ephemeral (EC2) hosts for remote development, and while I wasn't setting up a new machine frequently, knowing that I could do it with <5min of effort (and 15min of building Nix packages) eliminated a lot of anxiety.

You can just use git directly, no symlinking required. The home folder doesn't become a git repo itself, the dotfiles are just a checkout from a bare repo: https://www.atlassian.com/git/tutorials/dotfiles

https://httptoolkit.com - HTTP debugging proxy with really easy one-click launch to intercept android devices/browsers/docker containers/etc.

> docker containers

heh, that's neat: https://github.com/httptoolkit/docker-registry-facade (Apache 2) although the rest of their stuff seems to be AGPLv3 https://github.com/httptoolkit/httptoolkit-android/blob/v1.3...

I'm the maintainer of HTTP Toolkit.

In general the source for core components that can't really be used for anything else is AGPL, but all the generally reusable libraries are Apache 2 or similar. The goal is to share as much as possible, and let everybody access the source for everything, and fork for their own use or submit modifications or whatever, but without the risk that a proprietary product runs off with the core product in a different direction. Seems to be working reasonably so far!

Regarding Docker, you might also be interested in https://github.com/httptoolkit/docker-socks-tunnel (1MB Docker container that runs a socks proxy, for tunnelling traffic between networks) and this detailed breakdown of how the whole Docker interception setup works under the hood: https://httptoolkit.com/docs/guides/docker/#the-technical-de...

Small AutoIt utility scripts, such as WhyNotWin11 and other applets by similar users using AutoIt to make VB6-era -esq programs. These are always neither motivated by lofty architectural goals to “do things correctly” of many collaborative open source projects that forgot about laymen-ergonomics entirely, nor user-acquisition driven dark-pattern minefields of sluggish eye candy entirely focused on exploiting the aforementioned laymen-approachability, instead just being small-scope, pragmatic UX solutions to solve minuscule pain-/friction-points in interacting with Windows that are too fragmented to be part of some overarching software utility. They replace the typical SEO shovelware web app/adware that you get when searching on Google for “how do you do X on windows” that sends you to some factory-stamped installshield executable which does nothing more than passing command line arguments to some existing open-source CLI software that neglected laymen-usability.

https://www.autoitscript.com/site/autoit/ says "AutoIt v3 is a freeware BASIC-like scripting language" and https://www.autoitscript.com/site/code/ just has " Here are some C++ source code samples from various projects of mine. Most are free to use but check any license files that accompany the downloads for details."

qpdf[1], and, in particular, libqpdf, is possibly the most useful PDF tool I've ever used, because it was the first library I found that works at the proper level of abstraction for dealing with the PDF file format on its own terms.

In other words, the library directly exposes the essential PDF object structure (pages, dictionaries, strings, numbers, streams, etc.) for easy editing, while abstracting away as much of the incidental PDF file structure as possible (encryption, compression, object references, the page tree structure, etc.).

Among many other applications, I've used it to

• Automatically repair minor PDF file format problems (of the sort that would be fixed by Open + Save in Acrobat).

• Concatenate multiple PDFs into a single PDF, adding a bookmark to the first page of each, with the bookmark title derived from information not contained within the PDFs or their file names.

• Losslessly reduce the size of PDFs in not-entirely-trivial ways. For example, I was given a ~1 TB set of PDFs that stored 1-bit monochrome scanned images as losslessly-compressed (RLE, LZW, or flate) 24-bit color images with every pixel either 0x000000 or 0xFFFFFF, but also stored color and grayscale images in the same way, and included important non-image data. libqpdf made it easy to loop through each PDF file, extract and analyze the pixel data for each image, and replace relevant images with JBIG2-compressed "true" 1-bit equivalents without otherwise modifying the PDF.

• Lossily recompress large images embedded in PDFs, but only if they matched certain criteria. Specifically, I had a large number of PDFs that contained lots of lossless high-DPI 4K screenshots of a specific application, where even relatively high JPEG compression maintained legibility, interspersed with images where such recompression was undesirable (photos, document scans, 1080p screenshots).

• Create PDFs by overlaying plain text on PDF forms — "paper" forms defined by PDFs, not PDF forms — without duplicating form content for each page.

[In the above examples, JPEG and JBIG2 compression was performed with other libraries, as these are out-of-scope for libqpdf itself.]

Interesting.

I must check out qPDF.

Have you tried out muPDF?

I have not, yet, but it looks interesting too.

theres a github repo somewhere of open source equivalents to paid software - anyone know what im talking about? i havent been able to find it since i saw it

I see that you said github repo, but my life experience has been that those "awesome" style repos are committed to once and then ignore all pull requests or issues going forward. Thus, I think the audience would be better served by AlternativeTo or one of its ilk, which offers a licensing filter on their lists (e.g. https://alternativeto.net/software/github/?license=opensourc... )

But, a quick search for alternative coughed up a few results, which exhibit the behavior I described https://github.com/RunaCapital/awesome-oss-alternatives#awes... https://github.com/btw-so/open-source-alternatives?tab=readm...

I have been a happy user for years and have made a donation too.

It imposes limitations on how one can use it https://freefilesync.org/faq.php#commercial which I don't believe squares up with its GPLv3 license. Between that, and there being no obvious response to any of the submitted patches or bug reports in the forum, I'd guess this is "fork-only open source" ala sqlite

20 years ago i discovered a project by a university in germany that implemented a well thought through object storage with connections to all sorts of messaging protocols.

it was used as a platform to research collaboration models.

fortunately, at the time some german academic institution offered grants to universities for publishing their projects as Free Software or Open Source, and so this platform was released under the GPL.

what is interesting about the platform is that it not only stores objects like say mongodb, but it also implements user and group management, a hierarchical access control system down to the object level, and messaging. further messaging implements pretty much all communication protocols out there: IRC, XMPP, SMTP, IMAP, and of course HTTP, FTP and more. and no, to get these it does not require a bridge to independent implementations of those protocols, but they are implemented natively into the server, and SMTP or IMAP or the webinterface will all directly access the same stored object.

what's more, the platform allows you to upload your own modules to extend it, which are stored in its object object storage, and can be updated at runtime. it has been used by the university to host various courses for more than 10000 users all handing in assignments at the same time.

i have been using this platform for my own websites pretty much ever since.

the university stopped development on the project more than a decade ago, but i forked it, and eventually added a REST API and implemented multi domain hosting on it so that i could serve multiple websites from the same service.

the code is old, and needs updating. TLS support is outdated, which is something that needs to be fixed before the project can be recommended to anyone else. the built in web templating system is using XSLT, which should be replaced with easier to use alternatives (or simply ignored, as as i do, by building all websites as SPA using the REST API instead. the REST API too, should be updated or replaced by GraphQL.

but aside from these problems the platform is usable like Backend As A Service. ever since adding the REST API, i have not done any custom backend coding, as the platform already provides any features i have ever needed.

the challenge throughout all this time has been to get other developers interested in using such a platform, instead of building yet another CRUD backend from scratch.

i don't currently have time to do any work on it (even its website is down), as i need to focus on paid engagements, but i have not given up hope to be able to revive it and make it popular some day.

Pushing the code to github might be a good starting point?

it's there (and on gitlab, where i prefer to work), but there are so many projects on there, that doesn't really help discovery.

link please

please email me. see profile.

So you think this does not get enough attention, but you keep it secret? Makes zero sense.

if you are interested, you can contact me. otherwise i'd like to avoid de-anonymizing my hackernews account.

I hear you, but for your consideration people create throwaway HN accounts all the time for commenting on sensitive topics, and thus one created to submit a link to GitLab for sure wouldn't stand out as belonging to you

yes, i could have done that. but to late now.

I may be able to contribute, what language is it written in?

glibc. Stop this and the world will come to a halt real quick.

x-cmd is a great CLI that I've been using lately. It's very lightweight (not exceeding 1.1MB), yet packed with numerous features. It provides a range of interactive CLI tools, currently boasting over 100 modules and close to 500 packages.

nice recommendation ~

It's quite a pleasant surprise to see other x-cmd users here. Indeed, x-cmd has proven its worth. I've successfully replaced my previous setup, including the oh-my-zsh theme and various version managers like pyenv and nvm, with x-cmd on my machine. It's streamlined my workflow considerably.

A awesome project !!!

55 stars only in Github. I am wondering what's wrong with it.

Shameless plug. My own one of course :)

So many great projects!

which of these are underrated and deserve more recognition?

I think only some are underrated, such as PiperTTS, Immich, HeidiSQL, and ShotCut. Also small tools like rsync are widely used, but their maintainers often don't receive much appreciation, as these tools are as common as hammers and screwdrivers. They need some love, thats why i have this list.
