## Best for

Teams whose coding agents keep rediscovering the same repository context on every task.

## Why it deserves attention

OpenWiki builds a navigable wiki from your repository and keeps it current by grounding each claim in source evidence, so later updates focus on what changed. It runs inside the coding agent you already use, borrowing its authenticated model session instead of asking for another API key, and supports Claude Code, Codex, OpenCode, Copilot, Cursor, Kiro, and others. Wikis can be linked into workspaces and searched over MCP, and the CLI supports scheduled updates. It is MIT-licensed with more than 17,000 GitHub stars and active development; wiki quality still depends on the chosen model, and large repositories take time to document.
