I think you might mean PyMuPDF (https://github.com/pymupdf/PyMuPDF https://github.com/pymupdf/PyMuPDF), a Python library built on top of the MuPDF C library (https://mupdf.com/ https://mupdf.com/). PyMuPDF and MuPDF are both available under dual open source AGPL and commercial licenses. They have been around for many years and are under continual development. [Disclaimer, i work for Artifex, who wrote MuPDF and recently acquired PyMuPDF.]
