langchain-ai/openwiki

OpenWiki runs as a CLI and uses an agent to read a codebase, write structured documentation, and keep that documentation updated as the code changes. The problem it is solving is real: codebase wikis rot the moment someone stops manually maintaining them. The agent-maintained angle is the differentiator — instead of a one-shot doc generator, it is designed to be re-run and to update incrementally. Honest reservation: this is an early-stage project from the LangChain team, which means the underlying agent will occasionally hallucinate relationships between modules, and the output quality will vary heavily with codebase structure. Also, the LangChain association means the dependency footprint is not small. Worth a Saturday test on a medium-sized repo to see if the output is useful enough to check in. -> Best for: technical PM or solo founder maintaining a codebase where onboarding docs are perpetually out of date
