Building bridges between open-source projects is a big part of why I joined @marimo.io. I got to know the @prefix.dev folks through @scipyconf.bsky.social, and worked together to make computational research easier to reproduce and share. Special thanks to @julianhofer.eu and Ruben Arts!

The Pixi team is at ROSCON in Toronto - come find the yellow backpacks if you want to chat! We keep spotting Pixi in so many cool robotics projects and it's making us proud. To get a glimpse of what we're working on, join the talk about the EU CRA this afternoon!

We made it easy to install Isaac ROS! The new `isaac-forge` repository contains many upstream NVIDIA Isaac ROS packages to make them installable with Pixi. You can test it today on your #NIVIDA #Jetson! No docker needed! github.com/wolfv/isaac...

Congratulations to the Mojo 1.0 release @Modular! So glad to have you in our community, and seeing @clattner_llvm on stage with `pixi` in the background was definitely a highlight for us.

playground.rattler.build got a redesign and a recipe generator for PyPI, CRAN and CPAN. Paste a package name, get a recipe.yaml back.

rattler-build now builds for iOS and Android. Conda packages on mobile. Yes, really.

pixi update --offline now resolves against only what you already have: the package cache and local file:// channels. Air-gapped machines, planes, CI without egress.

Prefix.dev - the Pixi company @prefix.dev · 31/08/2026
Pixi now fully supports archspec, so you can create CPU-optimized environments and let Pixi handle the installation logic. Read more about it in the blogpost we updated: prefix.dev/blog/buildi...

Any Rust, C++ or Python project on GitHub can become a global tool on your machine. No recipe, no manifest in the repo. Just name the backend.
081
Prefix.dev - the Pixi company @prefix.dev · 25/08/2026
Building a git repo that never heard of Pixi used to mean forking it. Now you declare the build backend inline and Pixi builds it from source.

Conda packages have extras now. Optional dependency groups you declare and then consume, via v3 repodata. Plus when conditions and variant flags.

[system-requirements] is deprecated. Platforms now carry the requirements themselves. CUDA and glibc constraints inline, and you can name a target what you actually call it: jetson-nano.

Lastly, I'm a contributor to the `pixi-build-mojo` backend, which is what @prefix.dev can use to build Mojo projects: pixi.prefix.dev/latest/build... And allows you to install dependencies directly from GitHub, which is really cool!

PEP 723 only covers Python and PyPI, so Pixi reads tool.pixi for the rest. Which means conda dependencies in a standalone script. gdal from a single file, no build step.
051
Prefix.dev - the Pixi company @prefix.dev · 12/08/2026
A single Python file can now carry its own environment. pixi run --script hello.py Pixi reads PEP 723 inline metadata. No pixi.toml, no .pixi folder, no lock file unless you ask for one.

Simple and reproducible NVIDIA CUDA development with Pixi is easier than ever, thanks to the new capabilities of `pixi-build`. In our blogpost we build a simple kernel to run Mandelbrot on the GPU! Learn more: prefix.dev/blog/cuda-pixi

More and more multi-output recipes are now building through conda-forge's new rattler-build based staging. Fast, modern, Rust-powered builds are landing in conda-forge, one recipe at a time.

pixi 0.76 can now run standalone python scripts in isolated, on-demand environments. dependencies live inline via PEP 723, like uv supports, but pixi can layer on conda and system dependencies too. fun to build this with @prefix.dev folks. coming to a @marimo.io notebook near you SOON.
Screenshot of a standalone Python script declaring Rich and the system package FFmpeg as inline dependencies, then running in an isolated environment with pixi run --script.

Security tip for conda package authors: prefer environment-variable JSON files over activation scripts. Activation scripts run arbitrary shell code on every activation. Plain env-var JSON does the same job in most cases, with none of the code-execution risk.

mise, the popular dev-tool version manager, just adopted sigstore-rust, one of our open-source Rust libraries, to verify signed artifacts. Always good to see our building blocks powering other tools in the ecosystem. That is what open source is for.

As our server grows (600+ channels!) we had to redesign our channel page. It offers you an easier way to find your own or other interesting channels to fetch packages from!

GLIM, the real-time 3D LiDAR SLAM framework, is now available on conda-forge. One-line install with pixi or conda instead of building from source. Good news for the robotics crowd. See it in action: www.youtube.com/watch?v=CIf...

Using bioconda usually means also configuring conda-forge and a few other channels by hand. Cumbersome, and easy to get wrong. Our new channel-relations CEP moves that info into repodata, so the solver just knows which channels belong together.

Pixi now supports relative `exclude-newer` definitions. This allows users to set a cooldown period before using packages from the internet. This helps avoid pulling in vulnerabilities discovered shortly after release.

We're thrilled to announce our second non-prefix core maintainer of Pixi! Welcome Lucas Colley! He's been an ESOC 2025 student and since then kept being active, both in the Pixi repo, our Discord community and by adding Pixi to Open-source projects like CPython, SciPy & Numpy!

Supply Chain Security is a hot topic! Pixi already has a "exclude-newer" feature to use a dependency cooldown for an extra layer of security. But we need to go further. As a first step, prefix will start quarantining packages on our mirror immediately when vulnerabilities occur.
