We just made it really easy to switch from conda to pixi. You can now use the pixi init - - import environment.yml to quickly port a conda project. You automatically get a pixi.toml, lockfiles and a powerful task system.

Our not-too-secret project allows Pixi to depend on packages built from source. Build graphs, multi-language support and more are handled transparently. Sounds great, doesn't it? Then let us finally introduce it officially! prefix.dev/blog/pixi-build

📣 Thank you to our Gold Sponsor @prefix_dev for supporting #SciPy2026! Your work on Python packaging makes the entire open-source ecosystem faster and more reliable. 🐍 🔗 scipy2026.scipy.org

@marktyrkba @rustrover @wolfvollprecht Do you mean Pixi? 😱?

@rustrover @wolfvollprecht @prefix_dev Instead of meeting up you should at least try to make your Software usable

Last Friday's Rust meetup in Berlin felt different 🦀Around 50 Rust developers joined us for an evening of talks, discussions, and community connections. @wolfvollprecht, founder and CEO of @prefix_dev, shared lessons learned building open-source software supply chain infrastructure for the Conda ecosystem, including Pixi and rattler. @FlorianGilcher, co-founder of @FerrousSystems and former Rust Core Team member, spoke about Ferrocene and safety-critical Rust. The best part was seeing the community shape the evening as it unfolded, with spontaneous lightning talks and thoughtful questions. Thanks to everyone who came, shared ideas, and made the evening what it was 🙏

@iuliaferoli This exact experience is what gets me out of bed in the morning! We, @prefix_dev, are working everyday to make this problem less of an issue! Please give Pixi another try and hit me up where you're blocked, we need to show the world what the experience could be!

Our #ROS Meetup will be on Tuesday, June 2nd, from 6-9pm local time in Vienna. Beer and wine will be free thanks to our friends and colleagues over at @foxglove, @prefix_dev, and @nomadicai. Please RSVP to attend: luma.com/xayz5tru

Scoped Trusted Publishers are also actually renamed to "Repository Access" because it's not just publishing. You can give any workflow on @github or @gitlab access to pull from your private channel easily with OIDC workload identity now.

Increasing the security of our users and the ecosystem is a top priority for us. That's why we've added OAuth2 login flow with scoped tokens for a better `pixi auth login` experience, and scoped "Trusted Publishers" & API Keys Read more: prefix.dev/blog/pixi-auth…

Thanks, Rubén Arts, for the opportunity of participate in the Pixi blog 🤓 prefix.dev/blog/pixi-at-i…

Guest blog post by @fmrico! See how Pixi and RoboStack improve his workflow at Universidad Rey Juan Carlos, improving teaching and robotics projects. prefix.dev/blog/pixi-at-i… #ROS #robotics #opensource

Did you know our dependency resolution library can solve Sudokus? Ben Moss just proved it by adding this example: github.com/prefix-dev/res…

Want to understand why more and more Scientific Python projects are addopting Pixi? We'll give an overview during our talk at #SciPy2026 !

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-file…

Hand-eye calibration on a Franka with RealSense cameras can be surprisingly brittle. After stitching together franka_ros2 + MoveIt Calibration a few times, I got tired of the setup overhead and built a unified repo for it. No Docker. No system ROS 2 install. One repo. Clone it, run pixi install, and start calibrating eye-in-hand or eye-to-hand. Thanks to @prefix_dev 's pixi-build preview feature, franka_ros2 + moveit_calibration can be built together in one shot. 🙌 Hope it saves someone a few hours: github.com/XingxinHE/fran…

Really fun blogpost by @kamathsblog about using Pixi to develop for a LeKiwi robot and controlling it with a Steam Deck! #ROS #HuggingFace #robots foxglove.dev/blog/teleopera…

Ever want to just quickly send some files? sendme by iroh is a very simple clean tool to get it done. No ssh or networking required, just a simple send-receive command. Quickly install it with Pixi 🚀

Pixi is gaining traction fast in robotics, so we built a dedicated landing page to help roboticists get up and running quickly. pixi.prefix.dev/latest/robotic… #ROS #robotics

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.

Database update completed! ✅ We feel that our website is now even snappier - thanks to the latest @PostgreSQL & @TimescaleDB updates.

This work was generously funded by @Anaconda for a workshop we held recently. You can find the book here: prefix-dev.github.io/rattler-book/

Our @tldejager wrote a "rattler book" that teaches the reader on how to write their own package manager, on top of our composable Rust libraries and the Conda ecosystem. Read all about it here prefix.dev/blog/the-rattl…
