## What it is
Maturin is a Rust-based CLI tool that builds and publishes Python wheels for crates with pyo3, cffi, or uniffi bindings, as well as Rust binaries packaged as Python packages. It requires minimal configuration and supports CPython 3.8+, PyPy, and GraalPy across Windows, Linux, macOS, and FreeBSD.

## Use cases
- build python wheels from rust crates
- publish a pyo3 extension module to pypi
- compile rust code as a python package
- cross-compile rust wheels for manylinux
- develop rust python extensions in a virtualenv
- package rust binaries as pip-installable packages

## When to choose
- you're writing Python extensions in Rust with pyo3, cffi, or uniffi
- you want minimal-config wheel building and PyPI publishing
- you need cross-compilation or manylinux-compliant wheels
- you target CPython, PyPy, or GraalPy across multiple OSes

## When to avoid
- you're building pure-Python packages with no Rust code
- your extension is written in C/C++ (use setuptools or scikit-build instead)
- you need deep integration with setuptools-rust-based build pipelines

## Facets
- artifact type: cli-tool
- maturity: active
- function: build-tool, package-manager, compiler, cli
