Introducing a New Identity for Prefix.dev
Since 2021 we've used the same identity and the website was mostly consistent, today we are transitioning to a new identity.

The Missing Piece to Software Package Management
Replace Brew, apt-get and Chocolatey with a single tool
Pixi — one package manager for Windows, macOS, and Linux. Fast. Declarative. Reproducible.
36k+ packages
Multi-language
Pin versions
GPU & SIMD support
To install, run the following command in your terminal:
curl -fsSL https://pixi.sh/install.sh | bash
Or find alternative installation methods in our documentation.
Pixi is Fast
Pixi is up to 10x faster than other tools (such as Conda or Mamba). It is written in Rust and downloads and installs packages in parallel.
Simple
Running a Pixi project is very simple, thanks to the integrated task system. Just clone a project, and run `pixi run start` to get going!
Open-Source
Pixi is licensed under the permissive BSD3-License. By default, Pixi uses packages from conda-forge which are free, and contain over 25'000 open source packages to choose from!
Reproducible
We use lockfiles to capture your environment perfectly. You run the same software locally as in the CI or your coworkers machine. No more: works on my machine!
Trusted by Engineers at
Use Pixi Everywhere
Reproducible Environments
Data Science
Spin up your data science environment in seconds—complete with Jupyter, pandas, SciPy and more. Reproducible across your team, on any machine (Windows, macOS, Linux).
Deploy with Ease
Robotics
Use pixi with RoboStack to set up, build, and deploy your ROS/ROS 2 workspaces—on your dev machine, in CI, and directly on your robot.
First-class support
Machine Learning
pixi has first-class support for PyTorch, CUDA, SciKit-Learn, Transformers and more. Set up multiple environments to control what GPU's and optimizations make sense for your project.
What Do People Think?
Fast Dependency Resolution for Everyone
Pixi has made managing build tool dependencies an absolute breeze. We use it daily at Lange Studios for building Godot from source!
CEO @ Lange Studios
I use pixi as my go-to for development environment and project management. It's easy to specify requirements make software that 'just works' and demos as simple as 'git clone && pixi run'.
Possibly the most boring package manager you'll ever use, in the best way possible.
prefix.dev has helped us provide tooling to manage dependencies at scale with unparalleled speed. It enables us to confidently introduce the latest software into regulated environments and ensure compliance at every step.
CTO QuantCo
Possibly the most boring package manager you'll ever use, in the best way possible.
Pixi is a fantastic tool to create reproducible environments for Python and beyond. Scientific computing requires fine version control of both source and binary packages, and Pixi by Prefix.dev offers a complete solution.
Janelia Research Campus, Howard Hughes Medical Institute
Pixi takes everything that's great about conda, and everything that's great about Cargo and combines it into one killer system.
As a long time conda user I've always wanted certain workflow enhancements. Pixi has delivered the workflow I've been looking for. The fact that I've seen it perform up to 40x faster is icing on top! I now reach for Pixi every time!
UC Berkeley
I use pixi as my go-to for development environment and project management. It's easy to specify requirements make software that 'just works' and demos as simple as 'git clone && pixi run'.
I simply won't use conda packages with any tool other than Pixi. I can't give up the incredible UX, and it's such an easy transition for teammates to make that I hesitate to even use the word "transition."

Other Tools We've Made
rattler-build
·Open Source Package Builder
Build standards-compliant Conda packages
rattler-build enables you to write simple recipes to build complex software into easy-to-install packages.
rattler
·Rust Crates for Conda Environments
Build your own conda tooling using Rust or Python
Rattler is a collection of Rust libraries with Python Bindings that makes it easy to create your tool based on the conda ecosystem. Used in production by pixi itself.
Dev Blog
Where we talk about software package and environment management as well as some of the puzzles we solved recently and in the near future.

Using Pixi as a System Package Manager with Shortcuts and Completions
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.

Building the Missing Piece Together
When we created Prefix.dev, our goal was simple: to solve the challenges developers face every day by providing a seamless, efficient, and intuitive platform. We believe in empowering developers to focus on what matters—building and innovating—while we handle the complexities behind the scenes.
