Starting points
What are you building?
Pick the closest match. Each link opens the catalog with a search already set for permissive licenses and projects active in the last 12 months, and you can loosen either filter. They are starting points, not endorsements: check the signals and the license text of every candidate you shortlist. Discovery only, not legal advice.
The catalog is for signed-in users, so these links ask you to sign in first. Sign up free or sign in.
