## What it is
uv is an extremely fast Python package and project manager written in Rust by Astral. It replaces pip, pip-tools, pipx, poetry, pyenv, virtualenv, and twine with a single tool that handles dependency resolution, lockfiles, Python version management, script execution, and package publishing.

## Use cases
- install python packages faster than pip
- manage python project dependencies with a lockfile
- replace poetry and pip-tools with one tool
- install and manage python versions
- run python scripts with inline dependencies
- run cli tools from pypi without installing globally
- create and manage virtual environments
- build and publish python packages

## When to choose
- you want a single fast tool for Python packaging, environments, and Python version management
- you need reproducible installs with a universal lockfile
- you want a drop-in pip-compatible interface with better performance
- you manage many projects or monorepo-style workspaces

## When to avoid
- you rely on tooling deeply integrated with pip or poetry workflows that uv does not support
- you need features still marked as preview or experimental
- your environment requires a pure-Python package manager

## Facets
- artifact type: cli-tool
- maturity: stable
- function: package-manager, build-tool, cli, developer-tools
- domain: developer-tools
- platform: windows, cli, cross-platform
- tags: python-packaging, dependency-resolution, virtualenv, lockfile, pip-replacement, rust, command-line, python, automation, macos, linux
