pixi and uv

pixi and uv are part of a new generation of environment management tools that are fast, ergonomic, and featureful.

Note

This is a note! Callout docs

Fast

pixi and uv are written in Rust as alternatives to slower Python-based tools conda and pip.

Ergonomic

pixi and uv implement commands and behaviors which replace frequently-manual work like initializing a project, installing dependencies, maintaining an environment spec file, and generating a lock file.

Featureful

pixi and uv include features that are often cobbled together from multiple tools under one roof.

uv supports creating a new environment (venv), installing dependencies (pip), managing a lockfile (pipenv), running tasks (invoke, nox, tox), and more.

pixi similarly supports creating new environments and installing dependencies (conda, mamba, micromamba), managing a lockfile (conda-lock), running tasks (same as above), and more.

Conclusion

Installing uv or pixi is quick and easy.

To install uv:

curl -LsSf https://astral.sh/uv/install.sh | sh

To install pixi:

curl -fsSL https://pixi.sh/install.sh | bash
