Pixi v0.75.0 now ships with an --offline mode. Install your environments directly from the shared cache, even on the train or plane! 🛫 Find out more here: pixi.prefix.dev/latest/refe...
The rattler-build playground got a bit fancier! Now also generates recipes for PyPI, CRAN, and CPAN upstream sources. Try it out under playground.rattler.build
Very cool to see `uv` adopting our @sigstore Rust crates to generate publish attestations for @pypi automatically. Pixi publish has it already, and it's nice. github.com/astral-sh/u...

Wolf Vollprecht, founder of Prefix.dev, creator of mamba & pixi, and conda-forge core maintainer, is keynoting Compute! Paris 2026! Hear his vision for the future of open-source tooling, performance, and data science infrastructure.
The latest version of Pixi comes with a new lockfile "v7"! It locks down build dependencies for the first time, making your builds even more reproducible. And of course fixes a number of issues. Read more in our blog post: prefix.dev/blog/lock-f...
Whats New with Lockfile Version 7
We have a new lock file, lets go over the changes.

Want to understand why more and more Scientific Python projects are addopting Pixi? We'll give an overview during our talk at #SciPy2026 !
Are you dreaming of your own specialized *-forge? Our new build tool "rattler-build" makes it simple. Check out our new docs on how to create a custom "r-forge", "rust-forge", "ruby-forge", ... rattler-build.prefix.dev/latest/tips...
RISC-V in Europe and China has real momentum. Pixi actually has supported this new hardware architecture since a while, but the @openKylin project has made it real. In this blog post we explore how Pixi support RISC-V! prefix.dev/blog/pixi-o... #RISCV #EuroHPC
Pixi supports RISC-V
As the RISC-V ecosystem matures from silicon to software, one piece has been missing: a modern, cross-platform package manager that makes it as easy to develop on RISC-V as on x86 or ARM. That changes today. Pixi now natively supports RISC-V (riscv64), bringing the full power of the conda ecosystem to open hardware.

Bioconda now recommends Pixi ahead of conda and mamba as the way to get started. This means a lot to us. We're all-in on making Pixi the best tool for scientific package management.
"Building From Source Shouldn't Be This Hard" That's our motto, read our latest blogpost to understand what we're building and how Pixi already helps you with today! 🗞️ Read it here: prefix.dev/blog/buildi... #pacakgemanagement #pixi #ROS #condaforge
Building From Source Shouldn't Be This Hard
Pixi-build is being designed to make package building easy, reproducible and maybe even fun!

No more duplicate dependencies in pyproject.toml! Pixi Python packages can now set `ignore-pypi-mapping = false` to automatically convert `pyproject.toml` dependencies into conda package requirements. The goal is no configuration, this is a step in that direction!
The notebook.link team is building "serverless scientific computing" on top of the modern Conda ecosystem & the prefix.dev package server. Read the guest blog on how they shipped interactive WASM for Python, R, C++, Fortran and more: prefix.dev/blog/server...
How notebook.link Scales Without Backends
Notebook.link combines WebAssembly and the conda ecosystem to deliver scalable, serverless computing environments that run entirely in the browser. No backend. No scaling headaches. Just instant, collaborative scientific computing for everyone.

Seeing the amazing FreeCAD 1.1 update makes me really proud that development of FreeCAD is supported by Pixi: www.youtube.com/watch?v=bYd... - great stuff!
FreeCAD 1.1 is Finally HERE — It’s a GAME CHANGER ! (Major Updates you missed)

Don’t like writing recipes? With Pixi packages, it’s a lot less work to package up remote projects! This is all the configuration needed to build the ruff project into a conda package with Pixi. 🤯
Pixi can now natively build R packages - for your own packages or thirdparty packages from CRAN or Github. The new `pixi-build-r` build backend makes it possible. pixi-build-r will install compilers, system-level dependencies and R / r-packages from @condaforge.
More Pixi stakeholders! Thanks Pavel and @quantco.com for being true Pixi & @conda-forge.org supporters.
Exciting news! We're thrilled to welcome Pavel as our first Pixi core maintainer from outside Prefix! With his extensive contributions, we have full confidence in his stewardship of the project. Thank you for your past work, and here’s to an even stronger collaboration ahead!
The RFC period has started on the "staging cache" CEP for the v1 recipe format. This might sound like gibberish but is a powerful feature that will allow us to convert more (complicated!) packages on @condaforge to the V1 recipe format!
You can now install the Open-Source physics engine, Newton, with Pixi! 🤖 Getting a full humanoid robot simulator has never been easier, just run one command! Check out the original announcement: github.com/newton-phys... #robotics #NVIDIA #warp #newton
We improved our package builder Rattler-Build a lot over the past months, so we wrote a blog post about it! prefix.dev/blog/whats-...
You thought Pixi was only for data science and Python?! Nope! Pixi is the perfect tool to manage your Kubernetes deployments, turbocharged by the github-releases channel we can offer many of the most used packages! No more curl-pipe-to-bash. Read more: prefix.dev/blog/kubern...

If you've ever spent 20 minutes debugging CI because helm was the wrong version, this post is for you.

Europe and China are both investing heavily in RISC-V chips. Thanks to the OpenKylin project the @conda-forge.org project is making progress as well. Today I ran Pixi on RISC-V for the first time. If you're investing in RISC-V infrastructure and want the package tooling to match — let's talk.

The latest Pixi releases and installer on Windows are properly signed with a Microsoft Certificate. Would it be useful to integrate signing for macOS and Windows into rattler-build?
Everyone loves shell completions, right? With carapace, you get amazing shell completions for most CLI tools, including Pixi since the latest release. This works on all platforms and shells.
Pixi skills are kinda cool. A couple extremely useful ones already hosted on prefix – such as the `conda-forge` skill, or the `rattler-build` skill. It's useful because it contains a bunch of expert knowledge, digestible for agents.
The @condaproject is moving forward with formalizing the current implemented standards! Strengthening the whole ecosystem and promoting collaboration.
rattler-build handles thousands of real world packages, and they often come with small patches. Historically, we used a mix of `git apply` and `patch`, but both have issues for cross-platform compatibility with a wide range of real-world patches. Now, we have our own Rust library
Last weekend I made `reportlab` a noarch package on @condaforge and added `pycairo` to emscripten-forge. Now you can easily generate PDFs in notebook.link! This is critical for a lot of agentic "business use cases".
