Pixi gives you reproducible, cross-platform environments. No more 'works on my machine.' No more broken CI. Just one command to running code.
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.
Parallel downloads, a Rust-native solver, and smart caching make Pixi up to 10× faster than conda or mamba.
Clone any Pixi project and run it instantly. Built-in task system included.
Access conda-forge's full ecosystem: Python, R, C++, CUDA, Fortran, and more. Plus GPU & SIMD support out of the box. BSD-3 licensed.
One lockfile captures your entire environment. Your laptop, CI, and your coworker's machine all run identical software. Every time.
ML & Data Science | Robotics | Scientific Computing | HPC & Simulation | Embedded Systems
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).

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.
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.
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.
Fast Dependency Resolution for Everyone
rattler-build enables you to write simple recipes to build complex software into easy-to-install packages.
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.
Where we talk about software package and environment management as well as some of the puzzles we solved recently and in the near future.

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.

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

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.
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.
