Python uv
Overview
uv is an extremely fast Python package and project manager written in Rust, designed to replace pip, pip-tools, pipx, poetry, pyenv, and virtualenv. It provides unified project management, dependency resolution, Python version management, and tool execution with 10-100x speed improvements over traditional tools.
Key capabilities: Project initialization, dependency locking and syncing, Python version management, PEP 723 inline script dependencies, ephemeral tool execution via uvx, monorepo workspaces with shared lockfiles, and package building/publishing.
When to use: Python project initialization, dependency management, virtual environments, Python version pinning, running scripts with inline dependencies, monorepo workspaces, tool execution, publishing packages.
When NOT to use: Non-Python projects, conda-managed scientific computing environments with system-level binary dependencies, projects locked to legacy setup.py-only workflows.
