conda-forge

We “conda” believe it! In collaboration with 7ASecurity and @sovereign.tech, we carried out an audit of conda-forge. Read the details at our blog: ostif.org/conda-forge-...

@conda-forge.org and @conda.org are essential components of our stack. Thus, it is natural for us to work with the community there to make it ready for upcoming cyber(security) regulations. Read about our efforts at tech.quantco.com/blog/conda-r...

Reach out, if you would like to collaborate!

The documentation of @conda-forge.org is improving with example recipes for Go and Rust packages – providing useful starting points to get MORE packages into our ecosystem!

I'm really looking forward to getting to teach this tutorial with @ruben-arts.bsky.social and John next week at #SciPy2025! This has been fun to collaborate with them on to create. I hope tutorial participants enjoy it and come away feeling they have a whole new toolkit to empower themselves with!

Virtual Packages in the Conda ecosystem Virtual packages are a neat trick to inject system requirements into the SAT solver and resolve for compatible packages automatically. In this blog post we talk about how they are used in the Conda ecosystem to support complex cross-platform package distributions.

Ever wondered how Conda and Pixi "know" to install CUDA packages only on GPU machines? 🤔

Meet virtual packages - a clever solution to inject system compatibility information to the SAT solver to ensure compatibility.

Demystifying conda packages!

Celebrating 4 incredible years with ‪@rjai.me‬! 🌟 As a conda steering committee member and conda-forge core team member, Jaime helps coordinate efforts that enable scientific breakthroughs. Here's to more years of community-driven innovation! 🙌 #CommunityImpact #OpenSource

S3 support in Pixi and rattler-build We're excited to announce S3 support across our entire toolchain – rattler, pixi, and rattler-build now support the most common cloud storage standard, thanks to contributions from our friends at QuantCo. This vendor-agnostic approach to distributing Conda packages represents a major step forward for the ecosystem, offering teams the flexibility to host packages on any S3-compatible provider (AWS, Cloudflare R2, Backblaze B2, Hetzner, and more) with built-in authentication and minimal vendor lock-in.

These days you can easily use S3 buckets to host your Conda packages. @quantcotech folks have implemented support across pixi, rattler and rattler-build.

We're excited because we want Conda packages to be used everywhere without vendor lock-in!

🚀Last week, the #ScientificPython Developer Summit brought together 32 package maintainers from across the ecosystem at eScience UW in Seattle!

✨It was a great opportunity to collaborate on improving the tools that power scientific Python research.🧑🏽‍💻

Thanks to everyone that joined! 🧡

npm: @conda-org/rattler Javascript bindings to the rattler library. Latest version: 0.3.0, last published: 10 minutes ago. Start using @conda-org/rattler in your project by running `npm i @conda-org/rattler`. There are no other projects in the npm registry using @conda-org/rattler.

New release on @npmjs - the rattler WASM/JS bindings are now published under "@conda-org/rattler". Why would you want Conda packages in the browser? – to install WASM modules for Python, R, Lua, C/C++ and more, or build your own WASM powered applications.

Amazing blog post about using Pixi for ROS 2 on Windows. We're happy about the shoutout – that's the kind of complex setup that we want to make extremely easy with Pixi.

One of the fastest JIT in the world is now easy to install with `pixi` on Windows.

If you always wanted to try LuaJIT then you can just `pixi add luajit` – on Windows, macOS and Linux.

We recently celebrated 10 years of @condaforge on our Zulip. I'd love to hear your story if you are involved with conda-forge. The project has grown to over 30'000 packages, and still grows at a crazy rate.

New architecture dropping on @conda-forge.org – we're excited to help the effort of building Windows ARM64 packages!

Today we celebrate the 10th anniversary of conda-forge!

Our beloved Github organization was created around this time on Apr 11th, 2015.

uv-secure is now on conda-forge. If you're a conda fan too, I suggest installing as a @prefix.dev pixi global tool.

I'd like to expand the scope of uv-secure to scan pixi.lock files too... unfortunately @conda-forge.org has no API for listing known package vulnerabilities like PyPi that I know of.
