    How a project gets listed

    1. Found

      Every day, new repositories, npm packages and reported projects are collected. Nothing is copied from another list.

    2. Proven

      The source archive is read file by file. A call to api.typesafe.ai, an SDK import, a pinned jev model or a declared dependency counts. A README sentence, a comment, a test or a server imitating the API does not.

    3. Listed

      The project exists because of Jev, the proof sits in product code, and at least five people starred it. 1,786 more pass the proof but not the rest yet; they are in the JSON.

    Repositories that were read but not listed are published with the reason in not-listed.json. Missing a project? Open an issue with the file that makes the call.
