What is PEP 517?
PEP 517 defines a
standard interface between build frontends such as pip
and uv, and build backends such as Setuptools, Flit,
Hatchling, and PDM.
It allows projects to declare their build dependencies in the
[build-system] table of pyproject.toml.
Legend
- Green projects (288; 80.0%): declares a PEP 517 build backend
- Yellow projects (66; 18.3%): no PEP 517 backend, but a universal wheel
- Orange projects (2; 0.6%): no PEP 517 backend and no universal wheel
- Gray projects (4; 1.1%): no source distribution
The package ranking comes from Hugo van Kemenade. The complete build-system dataset is available as csv.
