uv

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

When to use uv

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

• The uv.lock file
• uv headers in requirements* files, e.g., "This file was autogenerated by uv"

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

• Poetry projects (identifiable by poetry.lock file)
• PDM projects (identifiable by pdm.lock file)
