Langhuan is an open-source knowledge-processing and retrieval service for teams that need to share knowledge capabilities across multiple apps over REST or MCP.
It doesn't generate final answers or take on agent orchestration; it turns documents into retrievable, traceable evidence and provides clear workspace isolation boundaries.
Product capabilities, source code, and technical documentation live in the the GitHub repository. If you spot a content error, an inaccurate technical description, or want to contribute material, reach us through repository Issues.
This site records the problems, trade-offs, and lessons from building enterprise agents and knowledge systems. Anything touching Langhuan capabilities or technical implementation comes with references for further reading, and significant updates to posts are noted in time.
