cibuildwheel

cibuildwheel is a tool from the Python Packaging Authority that builds Python wheels across macOS, Linux, and Windows and across multiple Python versions. Doing this by hand is tedious, and cibuildwheel handles the matrix on your CI server. It is released under the BSD-2-Clause license.

It currently supports GitHub Actions, Azure Pipelines, CircleCI, and GitLab CI. Targets include macOS on Intel and Apple Silicon, Windows 64-bit, 32-bit, and Arm64, and Linux wheels for manylinux and musllinux on architectures such as x86-64, i686, aarch64, and ppc64le. It builds the wheels and also runs tests against them. The tool itself needs a recent Python, supporting the last three releases.

The documentation lives at cibuildwheel.pypa.io, and configuration is kept minimal, often a few lines in the CI file or project settings. It suits maintainers of Python packages with compiled extensions who need reliable binary distributions on PyPI without managing build machines for every platform.
