Open source technology matters. So does your support.

Your contribution during our Year-End Fundraiser strengthens the open-source foundations of cutting-edge technological advancement. In addition to bolstering critical infrastructure and operational services, NumFOCUS also uses funds from donations and sponsorships to support our projects’ user and developer communities. These programs include our Small Development Grants and our community engagement efforts through PyData and our Contributor Diversification and Retention research.
