Overview
uv is a blazingly fast Python package and project manager written in Rust, designed to replace tools like pip, pip-tools, pipx, poetry, pyenv, twine, and virtualenv. It offers 10-100x faster performance than pip, thanks to its Rust-based architecture and efficient dependency resolution algorithms. uv provides comprehensive project management with a universal lockfile, supports inline dependency metadata for scripts, and manages Python versions. Its pip-compatible interface allows for a seamless transition. It includes a global cache for dependency deduplication, optimizing disk space. Key use cases include managing project dependencies, running single-file scripts with isolated environments, installing command-line tools from Python packages, and quickly switching between Python versions. uv also supports Cargo-style workspaces for scalable projects and can be installed without Rust or Python.
