About DeepWiki
DeepWiki turns public GitHub repositories into a browsable wiki with architecture diagrams, source-linked documentation, semantic search, and context-grounded Q&A inside the codebase. It’s the free public version of Devin Wiki + Devin Search and supports programmatic access via a no-auth Model Context Protocol (MCP) server for reading wiki structure/content and asking questions. Private repositories are supported through a Devin account.
