The open license commons

Open source licensing, clearly documented.

OpenSource.ngo collects, organizes, and explains open source licenses while developing new licensing frameworks for software, AI, data, and emerging technology.

Why licensing matters

Licenses turn the principle of openness into durable permissions that developers, organizations, and communities can rely on.
