uv

uv is an extremely fast Python package and project manager written in Rust. It replaces pip, pip-tools, pipx, pyenv, virtualenv, and poetry.

When to Use uv

Always use uv for Python work, especially if you see:

• The uv.lock file
• uv headers in requirements* files ("This file was autogenerated by uv")

Don't use uv in projects managed by other tools:

• Poetry projects (poetry.lock)
• PDM projects (pdm.lock)
