# Projects

There are over 600 projects using scikit-build-core on PyPI (as of May 2025).
This is a selection of some of the projects. Feel free to add your own project
to `docs/data/projects.toml`. The following selection was primarily constructed
by looking at the [top 15,000](https://hugovk.github.io/top-pypi-packages/) most
downloaded projects on PyPI for top-level pyproject.toml's in SDists that use
scikit-build-core.

In addition, most of the [RAPIDSAI](https://github.com/rapidsai) projects use
scikit-build-core, but they are not published on PyPI. A few of them are:

- CuDF
  ([source](https://github.com/rapidsai/cudf/blob/HEAD/python/cudf/pyproject.toml))
- CuGraph
  ([source](https://github.com/rapidsai/cugraph/blob/HEAD/python/cugraph/pyproject.toml))
- CuML
  ([source](https://github.com/rapidsai/cuml/blob/HEAD/python/cuml/pyproject.toml))
- CuSpatial
  ([source](https://github.com/rapidsai/cuspatial/blob/HEAD/python/cuspatial/pyproject.toml))
- RMM
  ([source](https://github.com/rapidsai/rmm/blob/HEAD/python/rmm/pyproject.toml))
- Raft
  ([source](https://github.com/rapidsai/raft/blob/HEAD/python/pylibraft/pyproject.toml))

The [Insight Toolkit (ITK)](https://docs.itk.org), the initial target project
for scikit-build classic, has
[transitioned to sckit-build-core](https://github.com/InsightSoftwareConsortium/ITKPythonPackage/blob/master/scripts/pyproject.toml.in).
ITK currently provides one example of a production SWIG-based deployment. In
addition, dozens of
[ITK-based extension packages are configured with scikit-build-core](https://github.com/topics/itk-module).
