uv: Python Package and Project Manager

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

Navigation Rule

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

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

Exclusion Rule

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

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