Every work in the library, top first

Free to explore · curated by OneWave AI

1,407 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.

tech·an·dri·a/tɛkˈændriə/n.
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. 1,407 projects are queued and none has been approved yet. Everything unreviewed is discovery metadata imported from GitHub — listed, not vetted.

Ranked by total stars at the last daily refresh. This is not stars earned during the selected period. Star counts in the AI category are known to be inflated by fake-star campaigns, so activity and license are shown first.
