Blue Oak Council

Permissive licenses are the bread and butter of software development: simple, effective, and on just about everyone’s “go” list. But most information about free and open source software focuses on other, more complex licenses. The Council publishes this list to identify permissive licenses, so that everyone can recognize, rely on, and use them without expensive legal help.
