What this index tells you
We collect selected public repository metadata through GitHub’s official API and store it on our server. This is not a complete index of GitHub. Categories come from discovery queries and topics; a “skills” or “plugins” result is not a verified installation format. We do not run or audit the projects listed here.
Check the original repository’s licence, installation instructions and maintenance history before using it. Stars do not establish security, and a recent push does not prove that a project works. GitHub may have newer information than our last indexed record.
Search is lexical, not an AI answer engine. Short words and spelling differences can affect matches. This site is independent of GitHub. Report a wrong category, stale result or removal request.
