Show HN: Devbox – Containers for better dev environments
61 comments TheRealBadDev ar0.eu
I've been frustrated with dependency hell and clutter on my VPS from dev, so I built Devbox: a lightweight, open-source CLI tool that spins up isolated development environments using Docker. Each project runs in its own container, but your code stays in simple flat folders on the host machine—no messing with volumes or sync issues. Environments are disposable, so you can nuke and recreate them without losing your work. Key features: - Instant setup: `devbox init my-project` and you're in a fresh env with `devbox shell`.

- Configurable via JSON: Define packages, services, and more in a `devbox.json` file. Share it in your repo for reproducible setups—teammates just run `devbox up`.

- Docker-in-Docker by default: Build and run containers inside your env without extra config.

- Host-friendly: Edit code directly on your machine; the container handles the runtime.

- Templates for quick starts: Built-ins for Python, Node.js, Go, web dev, etc.

- Advanced options: Port mapping, env vars, resource limits, and even mounting your dotfiles.

It's FOSS (MIT license), Linux-focused (Debian/Ubuntu, or WSL2 on Windows), and super easy to install: `curl -fsSL https://devbox.ar0.eu/install.sh | bash`.

Check out the launch page and docs at https://devbox.ar0.eu, or the repo at https://github.com/itzCozi/devbox. I'd love some feedback, stars, or contributions to help grow this into a solid community tool!

FYI there's a well-starred, corporate-backed, similar functionality, Nix-based product with the same name:

https://github.com/jetify-com/devbox https://www.jetify.com/devbox

I usually don't take name clashes as seriously as some people here do, but when it's even in the same general niche, then that's not really a good look. It means the author failed to check the prior art - which is still fine for a (n+1)th hobby project, but not really for something more serious.

I thought that OP linked this devbox since so many subcommands from the cli are almost identical
TheRealBadDev OP
Again another oversight i also didnt relise i was mirroring docker commands and npm.
dbunskoek
Looks like a really fun project. You might want to reconsider the name though, since there is this other devbox from Jetify https://www.jetify.com/devbox that also received quite some attention on HN a while ago https://www.hackerneue.com/item?id=32600821

Yep, also Microsoft Dev Box: https://azure.microsoft.com/en-us/products/dev-box

I am not affiliated with Microsoft and I anal but I think dev box is fine. What we want to avoid is the term dev containers.

> I anal

There has to be a better way to phrase this

dp-hackernews
Yes, one would think it should have been presented as ANAL - which I think is the preferred way to present an acronym.
HatchedLake721
I think it’s reasonable. What’s another way, “I’m into backdoor stuff”?
swiftcoder
hey, I mean, buttplug.io could always use the contributors

The overlap with Jetpack's devbox name is not fine. Not morally, given the massive overlap in functionality between the two implementations. At the very least, their existence will prevent you from getting a trademark.

Both projects even use devbox.json for their definitions, for crying out loud. If your usage is not compatible with Jetpack's devbox.json, please switch to a different filename ASAP.

TheRealBadDev OP
I didn't realize our similarities until after i designed like all of it, i didnt do any research before hand sadly causing a lot of issues like this
gdotdesign
Also, DevBox (https://www.dev-box.app/) which is a collection of small tools for multiple platforms which I've been building since 2021.
FireInsight
Good point. I remember testing out Jetify's version a while back and switching away from it due to some issue I was having. I 100% thought this project was the same, just with a new website, as I did not remember much of the implementation details. Both of them even use `devbox.json` as the configuration file...
TheRealBadDev OP
Well its not the same programming wise so your problem might be fixed on ours but as i said in another reply i wasnt aware of the existing project and our overlaps i did no research before hand sadly

We've been using devcontainers for this, as it's already got good support in vscode. Could you perhaps "elevator pitch" the main differences between devbox and devcontainers?
whinvik
Yes, it feels very similar to Devcontainers.

But having tried Devcontainers a lot, it feels like its probably a complex specification since outside of VSCode every implementation has issues.

The CLI on Mac has weird user permission issues. Cursor's implementation is very flaky. Zed doesn't implement it yet.

So maybe there's space for more solutions in the same space but Devcontainers are very feature rich. And not to mention they have a huge user base via VSCode.

NitpickLawyer
The killer combo for us is remote+devcontainers. We use this for GPU access, so you can run a project on one or more GPUs that are on a remote server. You can spin up LLM stuff from a mac air and get the best of both worlds.
runelk
Nice! Do you have any tips or recommendations for a decent setup?
phrotoma
This has been my experience. I don't use VSCode and every time I've attempted to play with devcontainers I've just given up and gone back to a docker compose file. I love that they tried to extract the feature out into a stand alone thing, but the juice doesn't seem to be worth the squeeze yet.
immutology
Devcontainers work nicely with docker compose. It's the only way I use it... Really nice to have it all run containers.

https://code.visualstudio.com/docs/devcontainers/create-dev-...

phrotoma
Cool! I haven't seen this feature. Does it add some nice features beyond what a compose file could offer?
zeroq
Very good question, and even if your product is better it seems like an uphill battle. devcontainers are backed by MS/VS and they have good incentive to make them work.

Why you think your solution will succeed in long run and win over devcontainers?

globular-toast
I don't get how containers address "dependency hell". Is there some language that only supports installing libraries system wide? I've used a lot of different languages and yet to come across one.

I've worked on projects where the original dev has used containers for everything. It's super clunky and annoying. I don't want to use a different bash config just for working on that project. I've set my own up for a reason. All it makes me wonder is what are you afraid of? Why do you feel the need to isolate dev projects to this extent?

wiether
Isolation works both ways. By isolating your dev project, you don't expose your host to the mess the project can create... and you don't expose your project to the mess that can exist on your host.

With dev containers, you can define your ENV VAR, your aliases... independently from what exists on your host. And it will exists straight out the box: you checkout the project, launch the dev container and you're ready to go. As soon as you're done with this project, you delete the container and not a single trace of the project exists on your host. No matter how many custom things the project required to run.

neves
And since you have everything in a configuration file, it is breeze to transform your dev container in a production one.

C libraries are easiest to install system wide. The situation with multiple versions of libc is tricky to work with.

Not impossible, just not easy to comprehend by an average dev.

globular-toast
I'm kinda horrified to think there might be people writing C who don't know how to handle library versions. Somehow I don't think that is the target audience here, by I might be wrong.
Gabrys1
You might need to install libxml2 in order to use XML parsing library for your high level programming language.

You don't need to be writing C code to be affected by the dependency hell.

darkvertex
So this reinvents devcontainers? https://containers.dev

Why should we use yours? What does it do better or differently?

hk1337
While this is true, this project seems to wrap it up in a CLI package for starting and stopping projects. Whereas starting devcontainers, at least as far as I have seen, is always done via VSCode or IDE, so while it technically could be called CLI too, would be a lot more complicated than this project.
nickzelei
The devcontainers cli has existed for a while. Definitely not as smooth as using with vscode but it has all the main points.

https://github.com/devcontainers/cli

hk1337
TIL.

I'm not proponent of installing nodejs apps globally, npm install -g or yarn install -g

bartalama
There is also a CLI for dev containers. I use it for unattended builds.
exasperaited
I am afraid that despite all these options for containers, I still use my Vagrant scripts that build whole VMs based on my own schemes, use an apt package cache on the host and manage .ssh/config for me to make VSC remotes more seamless.

Almost all my stuff still runs on simple VMs because I cannot rely on my clients to take on more complex cloud infrastructure and I don't want to be stuck managing all of the things forever, so my life involves building customer VMs from build scripts that are adequately similar to my Vagrant boxes.

I use the VMs a lot for simple tests (e.g. of wordpress plugins and themes) so I have gone to the trouble of setting up Avahi with alias support, adding options for mailhog, different databases, different webserver setups I use for WP or Laravel or node.js, setting up an automated WP install etc.; so there are two or three starting configurations. I even had one for Magento before I realised I could be a lot happier without Magento in my life.

I guess it looks a fair bit like devcontainers now, and I should consider migrating over to that. But it's solid and under my control and that counts for a lot.

How does this compare to toolbx? (https://containertoolbx.org/)
Vinnl
And Distrobox: https://distrobox.it

One obvious one is that Toolbx and Distrobox are based on Podman, for one.

bogwog
> One obvious one is that Toolbx and Distrobox are based on Podman, for one.

And as a result, the containers are rootless.

kekqqq
I had a very strong personal opinion that, unless you expect frequent migrations or horizontal scaling, Docker is overkill and could be considered as bloat in many instances. After I joined my new company, I found out about devbox, and I love it. Now I use it for almost every personal project. It helps you to make the environment reproducible without sacrificing performance.

However, I use https://www.jetify.com/devbox.

TheRealBadDev OP
Yeah... i didn't realize this was a project before hand, do they use their own container framework? seems like too much for my small project but i can apricate your input.
evertheylen
I always like to see new projects using containers. Two questions:

- how is your devbox.json file different from a Dockerfile/Containerfile?

- does your project attempt to provide any isolation security-wise?

dns_snek
> does your project attempt to provide any isolation security-wise?

Considering that they provide Docker-in-Docker by default, this would have to be a "no" right now. Having the ability to launch Docker containers is equivalent to having root access on the Docker host by default.

erm, that name is already taken. https://jetify-com.vercel.app/docs/devbox/

Plugging my own tool. I use it for development and running semi-trusted or temporary tools, mounts the current/project dir for isolation, and shuts down automatically when it can.

TheRealBadDev OP
Hello!! All of your concerns have been addressed in a new commit of mine which is available to all of you now.

Added GPU pass‑through, engine‑agnostic containers (DEVBOX_ENGINE for Podman/rootless), and alternate config filenames to avoid Jetify collisions—while keeping a tiny, CLI‑first flow that works outside VS Code.

I thought you are talking about https://github.com/jetify-com/devbox :D

There is also Devpod with a nice UI.

I've been using Docker containers for quite some time to do web dev work. The one thing I haven't yet set up is doing mobile dev in a docker environment.

Does devbox support mobile development - Flutter or ReactNative?

TheRealBadDev OP
Yes hypothetically i haven't tested it but i am not sure why it wouldnt aside from machine constraints
jonotime
Would love to use something like this for NixOS as an escape hatch, but its debian only. DistroBox always gives me trouble.
tomas789
OP should consider changing their alias.
TheRealBadDev OP
Too deep in and i also make projects for a week then abandon them for a while so its not very much worth it i dont think
yakshaving_jgt
Anything to do with "dependency hell", I can't see a better solution than Nix.
parham
I’ve been doing a version of this using bash scripts for a long time! Thanks for making it

There are already dev containers

It's good that we get more options. I like ddev, will try this as well.

how does it compare to testcontainers? https://www.npmjs.com/package/testcontainers

Amazing amazing project, thank you for sharing this
TheRealBadDev OP
Oh! thank you for your appreciation means a lot.
