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

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!

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
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'.
It turns out there is a silver bullet for cross-platform dependency management and distribution: Pixi by prefix.dev. Seriously, delete everything else and try it out.
StereoLabs
Possibly the most boring package manager you'll ever use, in the best way possible.
Pixi takes everything that's great about conda, and everything that's great about Cargo and combines it into one killer system.

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
In scientific work, zealous dependency management is required to ensure repeatability. Pixi brings all the benefits of it without the headaches or overhead it often requires, and it's blazing fast on top of it.

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.
