OpenWiki

What is OpenWiki?

OpenWiki is an open-source command-line tool from LangChain that reads a repository and writes a linked Markdown wiki into an openwiki folder you control. Coding agents such as Claude Code, Codex, OpenCode, Cursor and GitHub Copilot CLI can search and read those pages through MCP tools, so they find context without crawling raw files. People can open the same pages or explore them as an interactive node graph with the visualize command. Each wiki page records the source evidence behind its claims, so later updates concentrate on code that changed, and interrupted runs resume page by page. You can start from inside your coding agent, which uses its own model session, or run the standalone CLI with one of fourteen model providers, a personal-knowledge mode and scheduled CI updates. The workspace feature links several repositories so one search covers all their wikis. OpenWiki itself is free to install from npm; the only cost is whatever your model provider charges for the generation run.

Use cases

• Generate a documentation wiki for a repository
• Give coding agents searchable repo context
• Search across several related repositories
• Refresh docs automatically from CI on a schedule
• Explore a codebase as an interactive graph
• Build a personal knowledge wiki from sources

Who it's for

• Software developers
• Engineering teams
• Coding agent users
• Platform teams

Why use OpenWiki

• Agents answer questions from a maintained wiki, which saves them from re-reading the whole repository for every task.
• Updates target changed code and stale claims, so documentation keeps up without a full rewrite each time.
• The wiki is plain Markdown stored in your repo, so you own it and can review it in a normal pull request.
• Linked workspaces let one search span a control plane, data plane and infrastructure repo together.
• No separate model setup is needed when you run it inside a coding agent you already use.

How to get started with OpenWiki

1. Install the package with npm install -g openwiki (Node.js 22.22.0 or newer is required).
2. Connect your coding agent with an openwiki integrations install command, or run openwiki --init to choose a model provider.
3. Ask the agent to initialize the wiki; it plans the pages and writes each one into the openwiki folder with source evidence.
4. Search and read the pages through MCP, link related repositories with openwiki link, or open the graph with openwiki visualize.
5. After code changes, run an update, or add one of the example CI jobs so a docs pull request opens on a schedule.

OpenWiki limitations

• Needs Node.js 22.22.0 or newer
• Coding-agent integrations support repository code wikis, not personal brains
• Connector-sourced context such as LangSmith is not yet supported in host-driven runs
• The graph viewer loads libraries from a public CDN, so it needs an internet connection

OpenWiki pricing
