The official @NVIDIA cuda-python project now also uses Pixi! #pixi #CUDA #NVIDIA

How to tell Pixi it can use CUDA? System requirements are the way to do this! #pixi #cuda #packagemanagement #software

Did you know the channels have a priority to them? This can be important when you mix multiple channels in your Pixi workspace.

Pinning a dependency in Pixi is defaulting to semantic versioning, but there are more styles that you can use!

Library developers, watch this! Pixi can help you test your dependency ranges using a different solve strategy!

Did you know there is more detail than just a version that you can give to a dependency?

Did you know that Pixi directly supports PyPI dependencies? Here are some tips on how to use them.

The official Python source code now includes Pixi manifests! This means you can install Python from source using Pixi.🥳 Special thanks to Lucas Colley and @MissingClara

We worked with AWS Deadline Cloud to build a simplified "publish to channel" workflow in rattler-build. All our tools now support native authentication to Amazon S3 (incl. the recently launched `aws login` and OIDC)! Read more in the blog post: prefix.dev/blog/aws-s3...

Anaconda.org and conda adopt sharded repodata! 🚀 CEP 16, introduced by @prefix.dev, splits the massive repodata files into per-project shards. This allows clients to only fetch what they need, resulting in significant speedups! Instructions to opt-in and benchmarks at buff.ly/XUSXp9h

Congratulations to our friends at Anaconda for shipping CEP-16 (sharded repodata). If you use conda-forge from anaconda.org servers, pixi & rattler-build got magically a lot faster! conda.org/blog/sharde...

A conda package from GIT SOURCE? How?! 🤯 We might have been hinting at "pixi-build", but now we're unveiling what makes it work: pixi build backends. A build backend basically produces a "recipe" from language-specific metadata, and pixi build orchestrates the build.

Our ESOC (the European version of GSOC) student Swastik Patel blogged about his experience with prefix this summer. Thanks for pushing `pixi` and `pixi-extensions` forward, Swastik 🚀 prefix.dev/blog/esoc-i...

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

While I was at @pydataparis.bsky.social , I did not spend much time on @conda-forge.org, but in that week, at least some important milestones happened for the Python 3.14 migration, e.g. unblocking everything that depends on pandas. More details can be found in my report: uwekorn.com/2025/10/16/w...

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.

We're launching our new identity today! Do you like it? Read all about it: prefix.dev/blog/new-lo...

The amazing @catppuccintheme has chosen the magic wand as the icon for a Pixi manifest. Should we make it the official Pixi logo? Don't worry, Paxton (our mascot) will stay!

Interested in how Pixi will enhance the lives of ROS developers? Join our talk at #ROSCon2025! Or come visit @rarts_ruby and @baszalmstra at the Startup Alley! #ROSCON #Robotics @OpenRoboticsOrg

Pixi Global is known as a tool to manage CLI applications, but did you know that you can also install shell completions and even graphical user interfaces with it? Learn more by reading Lucas' and Julian's blog post: prefix.dev/blog/using-...

Ever wondered where all my GitHub contributions come from? I have document a week's worth of @conda-forge.org contributions: uwekorn.com/2025/09/18/w... I plan to do this for 2-3 more weeks to get an overview where I spent my time. I hope there is also content in there that helps others.

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...

🔒 We're dogfooding sigstore attestations for our nightly releases of build backends. Really nice to see it in action! We will blog more about pixi-build and pixi-build-cmake soon.

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.

Exciting news! Pixi just hit 5k stars on GitHub! 🌟 Big thanks to all our incredible contributors for making Pixi better every day! github.com/prefix-dev/... #stars #github #packagemanagement #softwareengineering

The FreeCAD project has pioneered the use of Conda packages to build AppImages, DMGs and Windows executables. Recently they made the switch to Pixi with great success. Read more in the guest blog post by Jackson Oursland: prefix.dev/blog/how-fr...

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...

Sneak peek of the content of the presentation we'll give tomorrow @SciPyConf We'll tell you about Game Changing features that are starting to be released in Pixi. Join us in the Ballroom at 15:00 cfp.scipy.org/scipy2025/t...

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-...

I'm really looking forward to getting to teach this tutorial with @ruben-arts.bsky.social and John next week at #SciPy2025! This has been fun to collaborate with them on to create. I hope tutorial participants enjoy it and come away feeling they have a whole new toolkit to empower themselves with!

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` 🎉
