Package management, finally solved
Stop debugging your environment. Start shipping.
Pixi gives you reproducible, cross-platform environments. No more 'works on my machine.' No more broken CI. Just one command to running code.
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.
10× faster installs
Parallel downloads, a Rust-native solver, and smart caching make Pixi up to 10× faster than conda or mamba.
One command to run code
Clone any Pixi project and run it instantly. Built-in task system included.
36,000+ open source packages.
Access conda-forge's full ecosystem: Python, R, C++, CUDA, Fortran, and more. Plus GPU & SIMD support out of the box. BSD-3 licensed.
No more "works on my machine"
One lockfile captures your entire environment. Your laptop, CI, and your coworker's machine all run identical software. Every time.

Introducing Pixi GUI
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.

From Dev Machine to Robot
Robotics
Set up, build, and deploy ROS 1 & 2 workspaces with Pixi and RoboStack - the same environment on your laptop, in CI, and on the robot itself. No Docker required.
GPU-Ready Environments
Machine Learning
PyTorch, CUDA, scikit-learn, and Transformers — resolved correctly the first time. Define separate environments for different GPUs or optimization targets, all in a single project.
Trusted by Default
Supply Chain Security
Publish packages from GitHub Actions without API keys using trusted publishing. Attach Sigstore attestations to every release. We're building security into the conda ecosystem from the ground up.

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.
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.
