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 | bash

7 Reasons to Switch from Conda to Pixi

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.

SEE PIXI IN ACTION


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.


Terminal
➜ pixi init project
✔ Initialized project in /home/user/project

➜ cd project
~/project
➜ pixi add python numpy cmake
✔ Added python 3.11.4.*
✔ Added numpy 1.25.2.*
✔ Added cmake 3.26.4.*

~/project
➜ pixi run python --version
Python 3.11.4

~/project
➜ pixi add python==3.10
✔ Added python ==3.10.0.*

~/project
➜ pixi run python --version
Python 3.10.0


COLLABORATE WITH DEVELOPERS

Great projects are the fruit of collective effort. Pixi makes onboarding and
collaboration simple and seamless.

 * Reproducibility: Always maintain updated lockfiles.
 * Multi-platform: Ensure compatibility across Windows, MacOS, and Linux.
 * Version Control: Leverage Git to keep track of your environment changes.


Terminal
~/project
➜ cat pixi.toml
[project]
name = "project"
version = "0.1.0"
description = "Example project"
authors = ["Pixi <hi@prefix.dev>"]
channels = ["conda-forge"]
platforms = ["linux-64", "win-64", "osx-arm64", "osx-64"]

[tasks]

POWERED BY OPEN-SOURCE CHANNELS:CONDA-FORGE, BIOCONDA, ROBOSTACK, AND MORE!

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.
