Someone releases a great tool with perfectly working pre-built binaries on Github, but there's no Conda package. Octoconda helps out: It takes the release artifact and re-packages it for use in the Conda eco-system.

TL;DR - we have extended the Rust crate diffy to be able to patch real-world source code with real-world patches, which is surprisingly hard! In the process we renamed it to flickzeug.

At the University of Washington Scientific Software Engineering Center (SSEC), our mission is to enhance our partners software development capabilities to bolster their research. In scientific research, reproducibility is the gold standard. The ability for another researcher to take your code, data, and environment to arrive at the exact same results is essential.

Hi, I’m Felix. I’m excited to share what I’ve been building over the past few months! Since last year I work as a working student at prefix.dev. As part of my bachelor's thesis, I designed and implemented a graphical user interface for the package manager Pixi, named Pixi GUI.

We worked together with AWS Deadline Cloud to improve S3 support in our tools! Pixi and rattler-build now seamlessly authenticate using default credentials on your system, making it simple to upload, download and index packages on S3 buckets.

Normally, development tooling and package publishing live in separate worlds: you use one workflow to build and test your software locally, and a completely different one to publish it. Wouldn't it be great to use the same manifest that describes your project environment to also define how the package is built, versioned, and released?

Hey there! I'm Swastik. I completed a 3-month internship at prefix.dev under the ESoC'25 (European Summer of Code) program, and this blog is all about my internship experience.

Developing Robots is hard; Pixi makes it easier by creating reproducible, cross-platform ROS development environments without Docker or Ubuntu lock-in.

Cross compiling is a fundamental capability in modern software development, allowing developers to build packages for different architectures without needing access to the target hardware.

Since 2021 we've used the same identity and the website was mostly consistent, today we are transitioning to a new identity.

Pixi Global can be used for much more than just downloading and exposing CLI tools. In this blog post, we demonstrate two capabilities of pixi global which are core to making it a featureful and powerful system package manager: shortcuts, and (auto-)completions.

Mutex packages are a useful mechanism to guide the solver towards certain dependencies, mutually excluding other dependency trees.

Painless dependency management (including shared libraries), monorepos and CI/CD is here for C++/CMake projects with Pixi.

We're pleased to announce that sigstore support is now in public beta on prefix.dev! The Conda ecosystem can now use Sigstore to enhance the Software Supply Chain Security with cryptographic attestations.

This is a guest blog post by Jackson Oursland - a FreeCAD maintainer and esteemed member of the conda-forge and Pixi community! FreeCAD uses Conda packages to build AppImages, DMG and Windows artifacts. Pixi greatly simplifies the developer workflow.

Package managers face a fundamental challenge: how to efficiently place files from a package cache into multiple environments without excessive disk usage or compromising isolation.

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.

At its core, a conda package really is just a "glorified" tarball—a compressed archive of files with some metadata attached.

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.
