Being built on cargo and rustc, maturin is limited by rust's platform support.
On GitHub actions, windows, macOS and linux are tested, all on 64-bit x86. FreeBSD is also tested though Cirrus CI, but might get removed at some point. Since CI is very time intensive to maintain, I'd like to stick to GitHub action and these three platforms.
The following targets are built into wheels and downloadable binaries:
- Windows: 32-bit and 64-bit x86 as well as arm64
- Linux: x86, x86_64, armv7, aarch64 and ppc64le (musl), as well as s390x (gnu)
- macOS: x86_64 and aarch64
Other Operating Systems
It should be possible to build maturin and for maturin to build wheels on other platforms supported by rust.
To add a new os, add it in target.rs and, if it doesn't behave like the other unixes, in
PythonInterpreter::get_tag. Please also submit the output of
python -m sysconfig as a file in the
It's ok to edit setup.py to deactivate default features so
pip install works, but new platforms should not

All architectures included in manylinux (aarch64, armv7l, ppc64le, ppc64, i686, x86_64, s390x) are supported. I'm not sure whether it makes sense to allow architectures that aren't even supported by manylinux.
CPython 3.7 to 3.10 are supported and tested on CI, though the entire 3.x series should work. This will be changed as new python versions are released and others have their end of life.
PyPy 3.6 and later also works.
manylinux2014 and its newer versions as well as
musllinux_1_1 and its newer versions
Since Rust and the manylinux project drop support for old manylinux/musllinux versions sometimes, after maturin 1.0 manylinux version bumps will be minor versions rather than major versions.
