<!--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, CircleCI, and GitLab CI - and it builds and tests your wheels across all of your platforms.


What does it do?
----------------

While cibuildwheel itself requires a recent Python version to run (we support the last three releases), it can target the following versions to build wheels:

|                    | macOS Intel | macOS Apple Silicon | Windows 64bit | Windows 32bit | Windows Arm64 | manylinux<br/>musllinux x86_64 | manylinux<br/>musllinux i686 | manylinux<br/>musllinux aarch64 | manylinux<br/>musllinux ppc64le | manylinux<br/>musllinux s390x | manylinux<br/>musllinux armv7l | iOS | Pyodide |

<sup>¹ PyPy & GraalPy are only supported for manylinux wheels.</sup><br>
<sup>² Windows arm64 support is experimental.</sup><br>
<sup>³ Free-threaded mode requires opt-in using [`CIBW_ENABLE`](https://cibuildwheel.pypa.io/en/stable/options/#enable).</sup><br>
<sup>⁴ Experimental, not yet supported on PyPI, but can be used directly in web deployment. Use `--platform pyodide` to build.</sup><br>
<sup>⁵ manylinux armv7l support is experimental. As there are no RHEL based image for this architecture, it's using an Ubuntu based image instead.</sup><br>

- Builds manylinux, musllinux, macOS 10.9+ (10.13+ for Python 3.12+), and Windows wheels for CPython, PyPy, and GraalPy
- Works on GitHub Actions, Azure Pipelines, Travis CI, CircleCI, GitLab CI, and Cirrus 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.pypa.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 | macOS ARM | Windows ARM | iOS |
|-----------------|-------|-------|---------|-----------|-----------|-------------|-----|
| GitHub Actions  | ✅    | ✅    | ✅       | ✅        | ✅        | ✅          | ✅³  |
| Azure Pipelines | ✅    | ✅    | ✅       |           | ✅        | ✅²         | ✅³  |
| Travis CI       | ✅    |       | ✅      | ✅        |           |             |     |
| CircleCI        | ✅    | ✅    |         | ✅        | ✅        |             | ✅³  |
| Gitlab CI       | ✅    | ✅    | ✅      | ✅¹       | ✅        |             | ✅³  |
| Cirrus CI       | ✅    | ✅    | ✅      | ✅        | ✅        |             | ✅³  |

<sup>¹ [Requires emulation](https://cibuildwheel.pypa.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>
<sup>² [Uses cross-compilation](https://cibuildwheel.pypa.io/en/stable/faq/#windows-arm64). It is not possible to test `arm64` on this CI platform.</sup><br>
<sup>³ Requires a macOS runner; runs tests on the simulator for the runner's architecture.</sup>

<!--intro-end-->

Example setup
-------------

To build manylinux, musllinux, macOS, and Windows wheels on GitHub Actions, you could use this `.github/workflows/wheels.yml`:

<!--generic-github-start-->
```yaml
name: Build

on: [push, pull_request]

jobs:
  build_wheels:
    name: Build wheels on ${{ matrix.os }}
    runs-on: ${{ matrix.os }}
    strategy:
      matrix:
        os: [ubuntu-latest, ubuntu-24.04-arm, windows-latest, macos-13, macos-latest]

    steps:
      - uses: actions/checkout@v4

      # Used to host cibuildwheel
      - uses: actions/setup-python@v5

      - name: Install cibuildwheel
        run: python -m pip install cibuildwheel==3.0.0b3

      - 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@v4
        with:
          name: cibw-wheels-${{ matrix.os }}-${{ strategy.job-index }}
          path: ./wheelhouse/*.whl
```
<!--generic-github-end-->

For more information, including PyPI deployment, and the use of other CI services or the dedicated GitHub Action, check out the [documentation](https://cibuildwheel.pypa.io) 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 license implications. Check the license for any code you're pulling in to make sure that's allowed.

Changelog
=========

<!-- START bin/update_readme_changelog.py -->

<!-- this section was generated by bin/update_readme_changelog.py -- do not edit manually -->

### v3.0.0

Not yet released, but available for testing.

Note - when using a beta version, be sure to check the [latest docs](https://cibuildwheel.pypa.io/en/latest/), rather than the stable version, which is still on v2.X.

If you've used previous versions of the beta:
- ⚠️ Previous betas of v3.0 changed the working directory for tests. This has been rolled back to the v2.x behaviour, so you might need to change configs if you adapted to the beta 1 or 2 behaviour. See [issue #2406](https://github.com/pypa/cibuildwheel/issues/2406) for more information.
- ⚠️ GraalPy shipped with the identifier `gp242-*` in previous betas, this has been changed to `gp311_242-*` to be consistent with other interpreters, and to fix a bug with GraalPy and project requires-python detection. If you were using GraalPy, you might need to update your config to use the new identifier.

#### v3.0.0b3

_28 May 2025_

- 🛠 Reverts the test working dir (when test-sources isn't set) to a temporary dir, rather than the project. (#2420)
- 📚 Docs now primarily use the pyproject.toml name of options, rather than the environment variable name. (#2389)

#### v3.0.0b2

_25 May 2025_

- ✨ Adds the [`CIBW_TEST_ENVIRONMENT`](https://cibuildwheel.pypa.io/en/latest/options/#test-environment) option, which allows you to set environment variables for the test command. cibuildwheel now sets `PYTHONSAFEPATH=1` in test environments by default, to avoid picking up package imports from the local directory - we want to test the installed wheel, not the source tree! You can change that, or any other environment variable in the test environment using this option. (#2388)
- ✨ Improves support for Pyodide builds and adds the [`CIBW_PYODIDE_VERSION`](https://cibuildwheel.pypa.io/en/latest/options/#pyodide-version) option, which allows you to specify the version of Pyodide to use for builds. (#2002)

#### v3.0.0b1

_19 May 2025_

- 🌟 Adds the ability to [build wheels for iOS](https://cibuildwheel.pypa.io/en/latest/platforms/#ios)! Set the [`platform` option](https://cibuildwheel.pypa.io/en/latest/options/#platform) to `ios` on a Mac with the iOS toolchain to try it out!
- 🌟 Adds support for the GraalPy interpreter! Enable for your project using the [`enable` option](https://cibuildwheel.pypa.io/en/latest/options/#enable). (#1538)
- ✨ Adds CPython 3.14 support, under the [`enable` option](https://cibuildwheel.pypa.io/en/latest/options/#enable) `cpython-prerelease`. This version of cibuildwheel uses 3.14.0b1.

    _While CPython is in beta, the ABI can change, so your wheels might not be compatible with the final release. For this reason, we don't recommend distributing wheels until RC1, at which point 3.14 will be available in cibuildwheel without the flag._ (#2390)
- ✨ Adds the [test-sources option](https://cibuildwheel.pypa.io/en/latest/options/#test-sources), and changes the working directory for tests.

    - If this option is set, cibuildwheel will copy the files and folders specified in `test-sources` into a temporary directory, and run the tests from there. This is required for iOS builds, but also useful for other platforms, as it allows you to test the installed wheel without any chance of accidentally importing from the source tree.
    - ~If this option is not set, cibuildwheel will run the tests in the source tree. This is a change from the previous behavior, where cibuildwheel would run the tests from a temporary directory. We're still investigating what's best here, so if you encounter any issues with this, please let us know in [issue #2406](https://github.com/pypa/cibuildwheel/issues/2406).~
    - If this option is not set, behaviour matches v2.x - cibuildwheel will run the tests from a temporary directory, and you can use the `{project}` placeholder in the `test-command` to refer to the project directory.

- ✨ Added `dependency-versions` inline syntax (#2123)
- 🛠 EOL manylinux options can no longer be specified by their shortname. Full OCI URL can still be used for these images, if you wish (#2316)
- 🛠 Build environments no longer have setuptools and wheel preinstalled. (#2329)
- ⚠️ PyPy wheels no longer built by default, due to a change to our options system. To continue building PyPy wheels, you'll now need to set the [`enable` option](https://cibuildwheel.pypa.io/en/latest/options/#enable) to `pypy` or `pypy-eol`.
- ⚠️ Dropped official support for Appveyor. If it was working for you before, it will probably continue to do so, but we can't be sure, because our CI doesn't run there anymore. (#2386)
- 📚 A reorganisation of the docs, and numerous updates (#2280)

### v2.23.3

_26 April 2025_

- 🛠 Dependency updates, including Python 3.13.3 (#2371)

<!-- END bin/update_readme_changelog.py -->

========

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.

If you are building Rust wheels, you can get by without some of the tricks required to make GLIBC work via manylinux; this is especially relevant for cross-compiling, which is easy with Rust. See [maturin-action](https://github.com/PyO3/maturin-action) for a tool that is optimized for building Rust wheels and cross-compiling.
