<!--intro-start-->
Python wheels are great. Building them across **Mac, Linux, Windows**, on **multiple versions of Python**, is not.
`cibuildwheel` is here to help. `cibuildwheel` runs on your CI server - currently it supports GitHub Actions, Azure Pipelines, Travis CI, AppVeyor, CircleCI, and GitLab CI - and it builds and tests your wheels across all of your platforms.
What does it do?
----------------
| | macOS Intel | macOS Apple Silicon | Windows 64bit | Windows 32bit | manylinux x86_64 | manylinux i686 | manylinux aarch64 | manylinux ppc64le | manylinux s390x |
|---------------|----|-----|-----|-----|----|-----|----|-----|-----|
| CPython 3.6 | ✅ | N/A | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
| CPython 3.7 | ✅ | N/A | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
| CPython 3.8 | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
| CPython 3.9 | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
| CPython 3.10¹ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
| PyPy 3.7 v7.3 | ✅ | N/A | ✅ | N/A | ✅ | ✅ | ✅ | N/A | N/A |
<sup>¹ Available as a prerelease under a [flag](https://cibuildwheel.readthedocs.io/en/stable/options/#prerelease-pythons)</sup><br>
- Builds manylinux, macOS 10.9+, and Windows wheels for CPython and PyPy
- Works on GitHub Actions, Azure Pipelines, Travis CI, AppVeyor, CircleCI, and GitLab CI
- Bundles shared library dependencies on Linux and macOS through [auditwheel](https://github.com/pypa/auditwheel) and [delocate](https://github.com/matthew-brett/delocate)
- Runs your library's tests against the wheel-installed version of your library
See the [cibuildwheel 1 documentation](https://cibuildwheel.readthedocs.io/en/1.x/) if you need to build unsupported versions of Python, such as Python 2.
Usage
-----
`cibuildwheel` runs inside a CI service. Supported platforms depend on which service you're using:
| | Linux | macOS | Windows | Linux ARM |
|-----------------|-------|-------|---------|--------------|
| GitHub Actions | ✅ | ✅ | ✅ | ✅¹ |
| Azure Pipelines | ✅ | ✅ | ✅ | |
| Travis CI | ✅ | | ✅ | ✅ |
| AppVeyor | ✅ | ✅ | ✅ | |
| CircleCI | ✅ | ✅ | | |
| Gitlab CI | ✅ | | | |
<sup>¹ [Requires emulation](https://cibuildwheel.readthedocs.io/en/stable/faq/#emulation), distributed separately. Other services may also support Linux ARM through emulation or third-party build hosts, but these are not tested in our CI.</sup><br>
`cibuildwheel` is not intended to run on your development machine. Because it uses system Python from Python.org on macOS and Windows, it will try to install packages globally - not what you expect from a build tool! Instead, isolated CI services like those mentioned above are ideal. For Linux builds, it uses manylinux docker images, so those can be done locally for testing in a pinch.
<!--intro-end-->
Example setup
-------------
To build manylinux, macOS, and Windows wheels on GitHub Actions, you could use this `.github/workflows/wheels.yml`:
```yaml
name: Build
on: [push, pull_request]
jobs:
build_wheels:
name: Build wheels on ${{ matrix.os }}
runs-on: ${{ matrix.os }}
strategy:
matrix:
os: [ubuntu-20.04, windows-2019, macOS-10.15]
steps:
- uses: actions/checkout@v2
# Used to host cibuildwheel
- uses: actions/setup-python@v2
- name: Install cibuildwheel
run: python -m pip install cibuildwheel==2.0.0
- name: Build wheels
run: python -m cibuildwheel --output-dir wheelhouse
# to supply options, put them in 'env', like:
# env:
# CIBW_SOME_OPTION: value
- uses: actions/upload-artifact@v2
with:
path: ./wheelhouse/*.whl
```
For more information, including PyPI deployment, and the use of other CI services or the dedicated GitHub Action, check out the [documentation](https://cibuildwheel.readthedocs.org) and the [examples](https://github.com/pypa/cibuildwheel/tree/main/examples).

Legal note
----------
Since `cibuildwheel` repairs the wheel with `delocate` or `auditwheel`, it might automatically bundle dynamically linked libraries from the build machine.
It helps ensure that the library can run without any dependencies outside of the pip toolchain.
This is similar to static linking, so it might have some licence implications. Check the license for any code you're pulling in to make sure that's allowed.

### v2.0.0 🎉
_16 July 2021_
- 🌟 You can now configure cibuildwheel options inside your project's `pyproject.toml`! Environment variables still work of course. Check out the [documentation](https://cibuildwheel.readthedocs.io/en/stable/options/#setting-options) for more info.
- 🌟 Added support for building wheels with [build](https://github.com/pypa/build), as well as pip. This feature is controlled with the [`CIBW_BUILD_FRONTEND`](https://cibuildwheel.readthedocs.io/en/stable/options/#build-frontend) option.
- 🌟 Added the ability to test building wheels on CPython 3.10! Because CPython 3.10 is in beta, these wheels should not be distributed, because they might not be compatible with the final release, but it's available to build for testing purposes. Use the flag [`--prerelease-pythons` or `CIBW_PRERELEASE_PYTHONS`](https://cibuildwheel.readthedocs.io/en/stable/options/#prerelease-pythons) to test. (#675) This version of cibuildwheel includes CPython 3.10.0b4.
- ⚠️ **Removed support for building Python 2.7 and Python 3.5 wheels**, for both CPython and PyPy. If you still need to build on these versions, please use the latest v1.x version. (#596)
- ✨ Added the ability to build CPython 3.8 wheels for Apple Silicon. (#704)
- 🛠 Update to the latest build dependencies, including Auditwheel 4. (#633)
- 🛠 Use the unified pypa/manylinux images to build PyPy (#671)
- 🐛 Numerous bug fixes & docs improvements
### v1.12.0
_22 June 2021_
- ✨ Adds support building macOS universal2/arm64 wheels on Python 3.8.
### v1.11.1
_28 May 2021_
- ✨ cibuildwheel is now part of the PyPA!
- 📚 Minor docs changes, fixing links related to the above transition
- 🛠 Update manylinux pins to the last version containing Python 2.7 and 3.5. (#674)
### v1.11.0
_1 May 2021_
- 📚 Lots of docs improvements! (#650, #623, #616, #609, #606)
- 🐛 Fix nuget "Package is not found" error on Windows. (#653)
- ⚠️ cibuildwheel will no longer build Windows 2.7 wheels, unless you specify a custom toolchain using `DISTUTILS_USE_SDK=1` and `MSSdk=1`. This is because Microsoft have stopped distributing Visual C++ Compiler for Python 2.7. See [this FAQ entry](https://cibuildwheel.readthedocs.io/en/stable/faq/#windows-and-python-27) for more details. (#649)
- 🐛 Fix crash on Windows due to missing `which` command (#641).
### v1.10.0
_22 Feb 2021_
- ✨ Added `manylinux_2_24` support. To use these new Debian-based manylinux
images, set your [manylinux image](https://cibuildwheel.readthedocs.io/en/stable/options/#manylinux-image)
options to `manylinux_2_24`.
- 🛠 On macOS, we now set `MACOSX_DEPLOYMENT_TARGET` in before running
`CIBW_BEFORE_ALL`. This is useful when using `CIBW_BEFORE_ALL` to build a
shared library.
- 🛠 An empty `CIBW_BUILD` option is now the same as being unset i.e, `*`.
This makes some build matrix configuration easier. (#588)
- 📚 Neatened up documentation - added tabs to a few places (#576), fixed some
formatting issues.

========
If you'd like to keep wheel building separate from the package itself, check out [astrofrog/autowheel](https://github.com/astrofrog/autowheel). It builds packages using cibuildwheel from source distributions on PyPI.
Another very similar tool to consider is [matthew-brett/multibuild](http://github.com/matthew-brett/multibuild). `multibuild` is a shell script toolbox for building a wheel on various platforms. It is used as a basis to build some of the big data science tools, like SciPy.
