PackagingCon is back in smaller format as a Devroom at FOSDEM 2026! We would love to see you there - and hear a lot of interesting talks. blog.ecosyste.ms/2025/11/06/f...

Missed us at @europython? Here is the recording: www.youtube.com/watch?v=HOq...

Learn how you can use Pixi with #ROS! We've put together some videos to showcase some Pixi features that are helpful for ROS development. YouTube Playlist: www.youtube.com/playlist?li... #ROSCon #ROSCon2025

What ROS at an Airport Apple Store?! Pixi makes installation so easy, we can install ROS anywhere now. #ROSCon2025 #ROSCon #ROS

What!? Multiple #ROS distros on one machine 🤯. No Docker, No VM, No dual-boot needed! www.youtube.com/watch?v=oiX... #ROSCon #ROSCon2025

Get your hands on stickers from @baszalmstra and @rarts_ruby at #ROSCon! Plus, catch a sneak peek of our latest development work!

In our little deep dive series we're now exploring how cross-compilation in the Conda ecosystem works: prefix.dev/blog/cross-c.... Back in the days, @conda-forge.org rolled this out widely to support osx-arm64 early on, and now for linux-aarch64/ppc64le.

I just tried Pixi from @prefix.dev for the first time.

I have submitted by first draft PEP! 📦 PEP 804 complements PEP 725 ([external] dependency metadata) with a mapping mechanism to translate ecosystem-agnostic identifiers to your favourite package manager. More info: - PEP 725: discuss.python.org/t/103890 - PEP 804: discuss.python.org/t/103891

Our server has recently delivered more than 1.000.000 packages for the first time. We've hit that mark a few more times since. Seeing this constant growth is fascinating and we are confident that our infrastructure will scale well beyond this number!

It's always a pleasure to get invoices from Azure. Why? Because it means our @condaforge.org sponsorship is being used! We have been sponsoring a big Windows machine through CirunHQ for the past year to build PyTorch, libmagma, and other hard-to-build software for Windows.

We're continuing our little deep dive series into Conda packaging. Mutex packages are useful to guide the SAT solver into specific parts of the dependency tree, and globally select either a GPU or CPU variant or similar features for an environment. prefix.dev/blog/what-a...

Package building with Pixi is being rolled out! Dive into our latest blog post on crafting C++ packages. And guess what? It’s not just for C++; Pixi plays nice with Python, Rust, ROS, Mojo, and beyond! prefix.dev/blog/pixi-b...

Today we're unveiling new Software Supply Chain features for the Conda ecosystem: the integration of Sigstore is in public beta on prefix! You can now create Sigstore attestations on Github Actions and cryptographically secure your supply chain with trusted publishing.

Another deep dive in the technology behind Conda package managers: file linking! Did you know that there are symlinks, hardlinks and reflinks? Reflinks are the best – copy on write is space efficient and isolates the cache. Learn more: prefix.dev/blog/what-l...

The documentation of @conda-forge.org is improving with example recipes for Go and Rust packages – providing useful starting points to get MORE packages into our ecosystem!

“Raise your hand if you were able to install everything with pixi and run the simulation-based inference tutorial notebook.” github.com/cranmer/sbi-...

Making it this easy to run complex robot simulations took >4 years. But the investment into Pixi and @RoboStack pays off - now you can start the new @GazeboSim / Turtlesim on macOS with a simple `pixi run start`. 🚀 #ROS #ROS2 #Gazebo @OpenRoboticsOrg

Ever wondered how Conda and Pixi "know" to install CUDA packages only on GPU machines? 🤔 Meet virtual packages - a clever solution to inject system compatibility information to the SAT solver to ensure compatibility. prefix.dev/blog/virtua...

Interested in Software Supply Chain Security? We are! That's why we helped to get `cosign` on conda-forge: `cosign` can be used to sign container images or other artifacts with `sigstore`, and you can now easily install it with `pixi global install cosign` 🎉

Thanks to a big internal Pixi refactor to support recursive source dependencies, we have much improved snapshot tests. Now we can observe all the actions Pixi takes to resolve, instantiate and build packages from source:

How do you make compiled software with hardcoded paths work anywhere? 255-character placeholders, $ORIGIN rpaths, and platform-specific binary patching. We explain how Conda packages achieve relocatability: prefix.dev/blog/what-i...

You might have already heard that Pixi is written in Rust, but did you know that Pixi is also useful when creating Rust programs? Watch Julian's talk "Pixi: the missing companion to cargo" to find out more: www.youtube.com/watch?v=Hso...

You should have told me when we had beers yesterday!

It all "just worked" from 1 command ... yes, that is the point!

Learning something new everyday by building cross-platform tools. The @condaforge m2-git behaved a bit weird when asking for `ref^{commit}` to get the latest commit. It's because MSYS does some glob-expansion and strips `{` and `}` when not using `set MSYS=noglob`...

These days you can easily use S3 buckets to host your Conda packages. @quantcotech folks have implemented support across pixi, rattler and rattler-build. We're excited because we want Conda packages to be used everywhere without vendor lock-in! prefix.dev/blog/s3-sup...

Amazing blog post about using Pixi for ROS 2 on Windows. We're happy about the shoutout – that's the kind of complex setup that we want to make extremely easy with Pixi.

New release on @npmjs - the rattler WASM/JS bindings are now published under "@conda-org/rattler". Why would you want Conda packages in the browser? – to install WASM modules for Python, R, Lua, C/C++ and more, or build your own WASM powered applications. www.npmjs.com/package/@co...

I know LuaJIT quite well from Love2d. It is indeed, quite speedy.

One of the fastest JIT in the world is now easy to install with `pixi` on Windows. If you always wanted to try LuaJIT then you can just `pixi add luajit` – on Windows, macOS and Linux.

We recently celebrated 10 years of @condaforge on our Zulip. I'd love to hear your story if you are involved with conda-forge. The project has grown to over 30'000 packages, and still grows at a crazy rate.

🌟 Spotlight on @julianhofer.eu! marimo + pixi: launch your notebooks in seconds. This starter template pairs marimo with pixi for instant env setup, built‑in testing, linting & CI/CD — so you can dive straight into interactive notebooks. Repo: github.com/Hofer-Julia...

Pixi support in PyCharm? Let's make it happen! Show your support by upvoting: youtrack.jetbrains.com/issue/PY-79...

Want to know how we made Pixi tasks even more powerful? Then check out @prsabahrami's new blog post! 🚀 prefix.dev/blog/less-b...

NumFOCUS is seeking our next Executive Director. We're looking for a strategic leader with a passion for open source and a commitment to equity. Learn more at bit.ly/42lraGZ

We wrote a blogpost about four exciting Conda Enhancement Proposals that we are working on in 2025. We are continuing to push the boundaries of what's possible with Conda packages. Read more: prefix.dev/blog/ceps_2025

NVIDIA's RAPIDS has turbocharged their @NVIDIA CUDA enabled package building by moving from conda-build to rattler-build, unlocking incredible speedups. 🚀 Source: github.com/rapidsai/bu... #nvidia #rapids #rapidsai #packagemanagement #conda #rattler

And much faster, too!

Watch Wolf explain the open CEPs we've written to advance the Conda ecosystem even further! 🎥 Livestream recording: www.youtube.com/live/zxquAg... 🪄 Tip: Use the chapters to find the CEP you're interested in! #conda #packagemanagement #pixi

We're happy to announce the support for the new (v1) recipe format on conda-forge: conda-forge.org/blog/2025/02... It was a long journey from coming up with a new, community approved spec to the first v1 recipe on conda-forge 🎉 – more details in the blog post.

It's pretty useful - especially when you want to port something over from brew to conda.

Come work with us!

On my way to @fosdem.bsky.social for the first time. Looking forward!
