Affiliated Projects

Affiliated Projects are focused on open source data science and make meaningful use of NumFOCUS-sponsored tools. Unlike Sponsored Projects, Affiliated Projects are not fiscally sponsored by NumFOCUS. We highlight affiliated projects to encourage the community to contribute to, promote, and support these open source tools!

Information on Fiscal Sponsorship

NumFOCUS provides a stable, independent, and professional home for projects in the open source scientific data stack through our fiscal sponsorship program. Learn about the benefits and requirements of project sponsorship through NumFOCUS and how to apply for fiscal sponsorship for your open source scientific computing project.


I use the tools supported by NumFOCUS almost exclusively, and it is difficult to imagine that something this meaningful can be both free and open!
