Show HN: Booste – Run apps in EC2, synced to your own text editor

I'm not trying to be snarky, but I genuinely feel like this could be implemented in less than 50 lines of code, maybe even 0 lines of code. You could just use bare ssh and rsync. Or you could use a remote volume mount. Or you could configure your docker client to connect to a remote docker server. There's a million different ways to do this and none of them are difficult, especially since this is targeted at engineers. I feel like I'm missing the point.

Hi Erik. I don't have the "it works on my machine" problem often, because I mostly work on my own or with very few other people, so I may not be your target audience.

I do have the "my laptop's hardware is not enough" problem, and my current approach is simply spinning up an EC2 instance with the desired resources and ssh into it and then cloning the git repo I'm working on.

Normally, I set up the instance once (I have to add the ssh keys to my github account), and (if it's an expensive instance) start/stop it so I don't leave it running over night. Not a big pain point as of how I currently work.

I could see myself using Booste if it allowed me to, with a single command, spin up and sync bigger instances that would run for a short period of time (eg, for ML model training) and then intelligently stopping/terminating it. Also, if you integrate more than one cloud provider, I could switch to the cloud provider best fit for my needs (cost, spin up time, latency, cpu/gpu, etc).

A couple thoughts on the current implementation (you might be already addressing): - I generally have more than one ongoing project at a time. Having everything in ~/Booste sync'ed with every box doesn't work for me (aside from the fact I'd use a different location) - I sometimes do need to work with big data files, and even if I don't want them syncing all the time, I do want a way to retrieve them easily. - I also often work with jupyter notebooks, so I'd need a way to tunnel (like I do with ssh)

Hope this helps and good luck!

What does this have over vim in mosh?

For years the ssh type lag made a remote editor too painful. Now we have things like mosh (with local echo) or syncthing or even native vim scp url support. What makes this better? I can’t tell from the website.

Hey HN, my name is Erik. This is my second Show HN for Booste – looking forward to your thoughts.

Booste is a command-line interface (CLI) that takes code written on your local editor/IDE and executes it in EC2. It runs remotely, in a pre-configured environment, but works with your local tools thanks to a background filesync process.

I want to fix the “it works on my machine” issue by bypassing personal machines entirely. As if Docker and Heroku had a lovechild.

How I came to building Booste:

Being a mechanical engineer turned software dev, there were countless times where my laptop (glorified tablet) couldn’t handle the workload needed, so I made Booste v1: a tool to host full desktop apps on AWS and stream it over RDP (remote desktop protocol) to clients. Some may recall the Show HN of Booste v1 six months ago.

Booste v1 sucked. Unusable latency, crap unit economics, and an infrequent pain point.

Through it all, the most common customer request was for a hosted VS Code. Prospective users wanted the perks of a cloud IDE (namely no-setup environments) but wanted to use their own tools. Diving deeper, it seems that most large companies build out their own (usually buggy) version of remote “devboxes”. The need seemed consistent and clear.

After the first Show HN and a failed W20 interview, I pivoted. I gutted the graphical desktop component, zoomed in on developers, and rebuilt as a CLI: Booste v2.

Running any shell command proceeded by the world ‘booste’ will trigger the CLI. The CLI tunnels that command through SSH to EC2, executes it there, and streams the stdout back down to your command line. Filesync makes sure EC2 is ready with your code.

Where “npm start” would run an app on localhost, “booste npm start” runs the same app in the cloud, visible to your team by URL. You can edit the code locally (VS Code, Sublime, Vim) and the save is synced and hot-swapped on the live URL within a second.

How the environment sharing works:

- The creator of a “Codebox” (EC2 instance) gets a barebones Ubuntu VM, on which they can set environment variables, install interpreters and packages, or set up databases. (pre-built env templates coming soon).

- Team members join the codebox by ID and password with a single “booste join” command.

- Codebox members get repos placed next to each other on the directory tree, so code doesn’t clash.

- There is “booste clone” feature in the works, where you can clone someone’s config without actually entering and messing with their codebox.

Under the hood:

-The CLI is built in Python using the Click library

-Codebox infrastructure is automated with the AWS SDK.

---Currently, they are EC2 instances, for the sake of getting the beta live. I plan to migrate to a more flexible containerized setup in the near future. Containers make much more sense.

-I built a Dropbox-like filesync, inspired by the rsync.

---It monitors a chosen directory on your local machine and syncs it with the codebox.

---When files in that directory are added, modified, or removed, the codebox reflects this within a second. Only differentials are sent.

---All communication is encrypted with frequently cycled keys, unlike rsync.

---Bulky files (ML data, dependency packages), which would otherwise slow rsync to a crawl are ignored by a customizable .boosteignore file.

-Since files sync asynchronously (on edit), the only latency is from ssh. There’s a 0.5 - 1 second delay on booste commands.

I’ve moving from closed to open beta. Fueled by covid and the now mandatory remote development teams, I made a free tier for you. Give it a try! Let me know what you like. Let me know what you hate.
