Scientific Python's nightly upload action is adopting pixi + grype: reproducible envs plus built-in vulnerability scanning in the release pipeline. Supply-chain security showing up right where maintainers already work. github.com/scientific-...
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!
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...
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...
Embeddable #CommonLisp running in #Python via passagemath-ecl, compiled to #WebAssembly using @emscripten.org, packaged in the @prefix.dev emscripten-forge-4x channel, running serverless in the browser in a @jupyter.org JupyterLite session via Notebook.link. notebook.link/github/passa...
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
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.
We've been driving one of the biggest changes to the conda ecosystem since its inception: repodata v3. Extras, conditional dependencies, and variant flags, expressed directly in the repodata. Now in beta 👇 prefix.dev/blog/repoda...

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-b...

📣 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
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-a...
A New Pixi Login Flow
Increasing the security of our users is a top priority these days. That’s why we’ve added OAuth 2.0 support to prefix.dev. You now have a fancy login-flow for Pixi and other tools.

Did you know our dependency resolution library can solve Sudokus? Ben Moss just proved it by adding this example: github.com/prefix-dev/...
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-f...
Whats New with Lockfile Version 7
We have a new lock file, lets go over the changes.

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/robo... #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.
Our Tim de Jager 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-ra...
The Rattler Book: Build your own package manager in Rust
To explain our core library, rattler, we recently wrote a book that walks you through building a fully working package manager from scratch.

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.
Over the past years, our platform has grown from just a few small channels to over 600 Conda channels storing more than 20TB of data. To help scale it further, today we are launching a fair pricing model based on your usage and needs. prefix.dev/blog/welcom...
Do you want to control your Spot robot dog from a Pixi environment? You can now easily install the spot-cpp-sdk from @condaforge! github.com/boston-dyna...
Pixi has a new subcommand: `publish`! It is now one step to build and upload a new package. Shortens your CI and improves the `pixi build` experience. Enjoy!
conda-mirror has a config file that let's you select what subset you want to mirror by familiar matchspecs. Did you know that conda-mirror was rewritten in Rust and uses the rattler libraries?
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...
