About Free-threaded Python Library Compatibility Checker

Project Overview

This project checks compatibility of top PyPI libraries with CPython 3.13t and 3.14t, helping developers understand how the Python ecosystem adapts to upcoming Python versions.

The Python Compatibility Checker runs daily tests on the popular PyPI libraries, attempting to build and test each library with development versions of Python 3.13t and 3.14t. The results are stored and presented in an easy-to-navigate format, helping developers and library maintainers prepare for upcoming Python transitions.
