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.
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!
