The uv build backend is now stable, and considered ready for production use.
An alternative to setuptools, hatchling, etc. for pure Python projects, with a focus on good defaults, user-friendly error messages, and performance.
When used with uv, it's 10-35x faster.
Jul 3, 2025 01:55Try it out by setting your project's build system, or running `uv init --build-backend uv`:
```toml
[build-system]
requires = ["uv_build>=0.7.19,<0.8.0"]
build-backend = "uv_build"
```
(In a future release, we'll make this the default.)
One underrated implication here: we can now build and publish your package without running or even installing Python.
In pure Rust, we can build your Python package, install it, publish it to a registry, etc.
