Supporting maintainers and protecting the Open Source ecosystem
How the OSI supports maintainers
OSI Approved Licenses
We provide a venue for the community to discuss Open Source licenses and we maintain the OSI Approved Licenses database.
Policy & Standards
We defend maintainers by educating legislators and policy makers about the Open Source ecosystem, its role in innovation and its value for an open future. We have engaged with NTIA, CISA, and policy makers of the EU Cyber Resilience Act, the EU AI Act, and the US Securing Open Source Software Act.
Advocacy & Research
We lead global conversations with maintainers, developers, non-profits, and lawyers to improve the understanding of Open Source. OSI investigates the impacts of ongoing debates from artificial intelligence to security.
