devenv 2.1: Nix with native suppor for zsh, fish, and nushell via libghostty devenv.sh/blog/2026/05...

👀👀👀 I really like devenv, this update looks great, updating now! devenv.sh/blog/2026/03... hopefully the mcp makes the experience a little smoother with claude too

#Devenv 2 is out and it is impressive! 😁 Great work team. Going to ride through in some personal projects to test out. I been moving to flake parts all my things, but still. Would like these dev shell benefits. 😎

tasks now show correct hierarchy in new tui

I've really been enjoying the `devenv` tools for `nix` environments. I've also made it so that AI agents for projects by default must use the `devenv` environment. It's not hardened or anything, but it is nice to be able to destroy environments safely on demand.

We've open-sourced oauth-kit, batteries-included OAuth/OIDC client library for Rust with normalized user profiles and plug-and-play axum integration. github.com/cachix/oauth...

Looking to do some devenv bug cleaning, anything that's top priority for you?

devenv 1.11 is here. - module changelogs for communicating breaking changes - profile configuration in devenv.yaml - secretspec 0.4.0 with multiple provider support and file-based secrets devenv.sh/blog/2025/11...

"devenv is objectively good, even if nix is cursed" - my colleague

Typically, cross-project sharing of best practices is done using scaffolding. It doesn't have to be that way - you can keep those in sync across monorepo or polyrepo setup by extending our modules. New guide: devenv.sh/extending/

devenv 1.9 is out and adds profiles A way to organize and selectively activate parts of your development environment. Create team modules with shared defaults, then use profiles to activate specific components. devenv.sh/blog/2025/09...

Absolutely packed room for @domenkozar.bsky.social talk on the future of CI with @nixos-org.bsky.social, @devenv_nix and others. Watch live at www.youtube.com/live/gdoYNYY...

We are happy to inform you that your proposal “What if GitHub Actions was local-first and built using Nix?” to NixCon 2025 has been accepted.

Now that I finally started using #devenv instead of flakes. I get it. It's way nicer that way.

Tuc tuc, anyone out here?

Stop fighting your ROS 2 environment! Tired of "works on my machine" nightmares, Ubuntu version lock-in, and Docker workarounds? Here's how to build faster, reproducibly, anywhere using Nix. Read my blog post: mykhailo.link/ros-devenv

Using elm2nix 😍

Coming in devenv 1.7: execute a task if certain files were modified

New devenv release is out, 1.6 brings quite a few significant bug fixes and a way to override developer environments using CLI options! devenv.sh/blog/2025/04...

Wrote a guide on how to use profiles with devenv.sh to provide different subsets of environments: github.com/cachix/deven...

Coming soon with devenv.sh 1.6

This day has come, what's the next hot thing?

Anyone tried Niri yet? Tempted to switch from i3 :)

Great to see all that interest for #Nix at yesterday’s Valencia Codes Level Up meetup. Many thanks to Deutsche Telekom IT for hosting the event. #vlccodes #devenv #linux #osx

pretty wild turnout for a technology that felt so niche just 3 years ago. and I really enjoyed watching someone else present about devenv for a change! thanks @jm2dev.bsky.social

We've reached 5k stars, thanks everyone for helping making developer environments somewhat easier ✨

Announcing Snix https://lobste.rs/s/s5p1ng ##nix

Finally made it work, local overlays in devenv 🎉

Our team is hiring. If Nix, NixOS and AWS sounds like fun check it out. grnh.se/7bba27744us

There's a lot of unchanneled anger in our society at these times

✨ devenv 1.4: Generating Nix Developer Environments Using AI devenv.sh/blog/2025/02...

I was very proud to present at this #FOSDEM #Nix & #NixOS track, and as every year it was great to see all the enthusiasm and amazing things the community is doing. My slides and recorded video about devenv.sh is available after the jump fosdem.org/2025/schedul...

Turns out we can do better than Nix flakes: gitlab.com/fluidattacks...

If I'm counting correctly, this is the fourth time curl has broken netrc support t.co/VuKt0l3iYO

Anyone looking for a full-time Haskell job? Asking for a friend. Someone that enjoys a calm environment and isn't looking for a crypto salary. DM

Reminder that you can get unfree+redistributable binaries (eg: CUDA, ZeroTier or MongoDB) from the nix-community.cachix.org cache. I noticed today that this knowledge is not widely available. hydra.nix-community.org/project/nixp...

When you google for Nix question and get your own answer from 2016

For companies looking to give back, Oceansprint is great ROI in terms of amount of dollar spent to positive outcomes. * github.com/nix-communit... * github.com/NixOS/nixpkg... * noogle.dev * ... And so many human connections that contribute to a more healthy ecosystem.

We just sent out confirmation for oceansprint.org to 27 sprinters and it wouldn't be possible without these sponsors. Thank you all!

I'm happy to announce Shopify as a gold sponsor of oceansprint.org!

I really really like Elm, but having no way to long-poll or use websockets is really frustrating.

A few more days to apply to oceansprint.org! A bunch of us with be hacking on tvix.dev 😎

Happy to announce clan.lol and secunet.com have joined as gold sponsor for oceansprint.org Considering applying to participate, still a few days left!

NixOS is literally a game changer. Managing the state of your entire OS in Git feels like a superpower. The only downside was dev environments (e.g. python venv), which is solved by devenv.sh. I made a very simple template I use every day w/ optional CUDA support: github.com/clementpoire...

Happy to announce Mercury as 🏆 sponsor of oceansprint.org! We're still looking for more sponsors to cover catering, so that we can hack all day on Nix :)

If you're not using devenv.sh, what is the main reason? Especially if you already gave it a try. Looking into what to hack on next.
