UV is a fast Python project tool for managing environments, dependencies, scripts, and releases with a clean command-line workflow.

Download uv python to streamline modern Python projects with a fast, reliable workflow for environments, dependencies, scripts, and releases. Built for developers who want one simple command-line hub, uv package manager keeps setup consistent from first clone to live production.

UV is built for developers who want a practical uv package manager that handles common project work without slow setup cycles. Whether you are trying uv install for the first time, replacing older uv pip habits, or organizing a uv virtual environment for a team project, the tool focuses on speed, repeatability, and clear command-line behavior.

In daily Python work, uv python, uv venv, uv sync, and uv lock help keep local development aligned with shared dependency rules. A repository can use uv add to introduce packages, uv run to execute scripts in the managed environment, and uv tool for command-line utilities that should stay isolated from project dependencies.

For teams that care about predictable onboarding, uv python package manager workflows make a repository easier to clone, configure, and run. Developers can document uv python install steps, use uv dependency management for consistent package resolution, and keep the same uv package installer behavior across laptops, CI runners, and production build systems.

1. Click the blue button above to open the official UV repository or project page.
2. Install UV using the recommended uv install method for your operating system and Python setup.
3. Create or enter a project, then use uv venv to prepare a clean uv virtual environment for dependencies.
4. Add packages with uv add, refresh dependencies with uv sync, and keep versions repeatable with uv lock.
5. Run commands through uv run, manage helper utilities with uv tool, and document uv python install notes for contributors.

• UV command not found? Recheck the uv install step, restart the terminal, and confirm the install location is included in your PATH.
• Wrong Python version selected? Use uv python commands to inspect available versions and align the project with its documented interpreter.
• Dependencies not matching teammates? Run uv sync from the repository root and confirm the uv lock file is committed and current.
• Package missing after install? Add it with uv add, then use uv run to execute the script inside the managed environment.
• Environment feels inconsistent? Recreate the uv venv and let uv package manager commands rebuild dependencies from project configuration.
• Unsure where to report issues? Check astral uv and uv github resources for release notes, discussions, and known behavior.
