pixi - powerful development environments on Windows, macOS and Linux
pixi is a fast software package manager built on top of the existing conda ecosystem. Spins up development environments quickly on Windows, macOS and Linux.
Automatic lockfiles produce reproducible environments across operating systems (without Docker!).
pixi supports Python, R, C/C++, Rust, Ruby, and many other languages.
Install pixi
To install, run the following command in your terminal:
curl -fsSL https://pixi.sh/install.sh | bashOr find alternative installation methods in our documentation.
rattler-build - the revolutionary build tool for the conda ecosystem now (almost) available in conda-forge.
Install your favorite tools system-wide and declaratively with the revamped pixi global!
Pixi is conda-compatible and comes with more speed, lockfiles and tasks. It is the next-gen package manager for Python and R and more.
Get started quickly
Our mission is to make pixi as simple as possible to use.
Getting a complex project running is as simple as pixi run start
- Reproducible: Work in dedicated, isolated environments that can still be recreated in a 100 years.
- Tasks: Simplify complex tasks by utilizing command shortcuts.
- CI: Replicate environments in CI with ease.

We are building on top of the Conda packaging ecosystem, which already provides thousands of packages for Python and other languages. We are looking at ways to unify this with the existing PyPI ecosystem. Learn more about the Conda ecosystem and its channels in our documentation.
