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...

Looking forward to this

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...

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

Pytorch + Ultralytics + ROS2 Humble on a Nvidia Jetson Nano with no Docker! Pixi, together with @condaforge and @RoboStack, makes this possible! #ROS #nvidia #opencv

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

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

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...

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!

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.

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...

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.

A brain in a conda package. What!? Read our latest blogpost on how to ship AI/ML models with conda packages! prefix.dev/blog/packag...

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".

Today was a good day for the Gnome ecosystem on @conda-forge.org! Two PRs merged to get more low level libraries: libadwaita, sassc, appstream, libshumate and json-glibc by Dan Yeaw and Felix Häcker.

We're taking supply chain security seriously for the Conda ecosystem. That's why we integrate deeply with the @projectsigstore ecosystem for attestation – soon coming to recipes as well to validate source code (sdist, github release) attestations.

Many RISC-V experts at the @condaforge meeting today. This is going to move quickly! Pixi also just finished building for RISC-V, exciting stuff.

We're excited to announce Pixi GUI, developed by our working student Felix Häcker! With the goal to make Pixi accessible to a wider audience while also empowering expert users. Find out more in Felix's blog post: prefix.dev/blog/introd...

🧪 Live experiment using notebook.link from @quantstack.bsky.social A notebook with DataLab-Kernel (github.com/DataLab-Plat...), a Xeus-Python JupyterLite-compatible kernel, connects automatically to a running local DataLab app (datalab-platform.com). No config. Auto-discovery. It simply works.

Should @OpenRoboticsOrg support #Pixi as an co-official installation tool on Linux? Join the converstation in the discource linked thread 🧵

We are thrilled to introduce notebook.link, a platform that lets you create, share, and run Jupyter notebooks instantly in your browser. Powered by JupyterLite and WebAssembly, it supports Python, R, C++, and a full in-browser terminal experience. 📖 Read the full story: medium.com/@QuantStack/...

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

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

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

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.

PackagingCon is back in smaller format as a Devroom at FOSDEM 2026! We would love to see you there - and hear a lot of interesting talks. blog.ecosyste.ms/2025/11/06/f...

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.

I just tried Pixi from @prefix.dev for the first time.

I have submitted by first draft PEP! 📦 PEP 804 complements PEP 725 ([external] dependency metadata) with a mapping mechanism to translate ecosystem-agnostic identifiers to your favourite package manager. More info: - PEP 725: discuss.python.org/t/103890 - PEP 804: discuss.python.org/t/103891

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...
