uv: Python Package & Project Manager

uv replaces pip, pip-tools, pipx, pyenv, virtualenv, and poetry. Written in Rust, 10-100x faster than alternatives. It is stable production software; minor versions can contain breaking changes, while patch releases are intended to be non-breaking.

Snapshot: v0.11.11, May 2026. The installed binary outranks this file. Run uv --version first, and uv <command> --help whenever a flag here doesn't land — the local install is often behind, and commands documented below (notably uv audit, preview-gated since 0.10) may simply not exist yet.
