uv is an innovative Python package and project manager developed by Astral, the creators of Ruff. Built in Rust, it offers remarkable speed improvements—10 to 100 times faster than traditional pip—while consolidating functionalities from multiple tools such as pip, pip-tools, pipx, poetry, pyenv, twine, and virtualenv into a single, efficient solution.
Key Features:
- Blazing Fast: Leveraging Rust's performance, uv dramatically reduces package resolution and installation times.
- Unified Toolset: Replaces several Python tools with a single, comprehensive manager.
- Project Management: Supports universal lockfiles, Cargo-style workspaces, and script execution with inline dependency metadata.
- Python Version Management: Installs and manages multiple Python versions seamlessly.
- Tool Execution: Runs and installs command-line tools from Python packages, similar to pipx.
- Disk Efficiency: Uses a global cache for dependency deduplication, saving disk space.
- Cross-Platform: Works on macOS, Linux, and Windows, with standalone installers available.
- Pip Compatibility: Offers a pip-compatible interface for familiar usage with enhanced performance.
Installation: uv can be installed via standalone installers or PyPI: ```bash
