Discover open-source AI tools.

1,004 apps, agents and plugins from GitHub, ranked on how actively they are maintained rather than on stars. Security review is in progress and every project shows exactly what has and has not been checked.

A library for the tools of a new age. After the Library of Alexandria, which copied every scroll that reached its harbour before it went on the shelf.
AI searches are sent to OpenAI.

Review is in progress. 1,004 projects are queued and none has been approved yet. Everything unreviewed is discovery metadata imported from GitHub — listed, not vetted.
