uv Package and Project Manager

Overview

uv is a fast Python package and project manager written in Rust. It serves as a single tool replacing pip, pip-tools, pipx, pyenv, virtualenv, and poetry. Use uv for dependency resolution, virtual environment management, Python version management, and project scaffolding.

Key characteristics:

• 10-100x faster than pip for dependency resolution and installation
• Built-in virtual environment management (automatic .venv creation)
• Lockfile support for reproducible builds
• Python version management without pyenv
• Cross-platform with no Python prerequisite for installation
