Python Build Standalone is maintained by Astral, the team behind uv, ruff, and ty.
The most common way to use these distributions is with uv. Run a managed Python installation with:
uvx --managed-python python
Choose a specific Python version or a free-threaded build:
uvx --managed-python [email protected] uvx --managed-python [email protected]+freethreaded
See the documentation for more, including running distributions and behavior quirks.
Prebuilt distributions are available on
GitHub Releases.
Choose an archive for your Python version, operating system, and architecture.
Most users should choose an install_only archive; full archives also contain
build artifacts for creating custom Python distributions.
See distribution archives for details on the available formats.
