Your codebase, documented in minutes.
Stop writing docs. Start shipping them.
Connect a GitHub repo. doc0 maps your code into a knowledge graph, then generates a full wiki — with API reference, AI chat, and changelog. Push code, docs update automatically. No writing required.
Free forever for public repos. No credit card required.

Real docs from real repos
Every wiki below was generated by doc0. Click any project to browse its live documentation.
Simple workflow.
From repo to docs in three steps
No config files, no manual writing. Connect a repo and doc0 handles the rest.

Connect your repo
Point doc0 at any GitHub repository — public or private. Choose your branch. That's it.

doc0 analyzes and generates
doc0 parses your code with tree-sitter, builds a knowledge graph of symbols and call relationships, detects API endpoints, extracts git history — then generates structured documentation from that deep understanding. Not just a README summary.
Ship

Publish and share
Your docs are live instantly. Push code and doc0 regenerates only affected pages — tracked through provenance records linking every page to its source files. Edit any page; your changes survive regeneration.
Two modes, one codebase.
Technical docs and user guides
Both generated from the same repo. Both always current. No one has to write or maintain them.
Built for your engineering team
Architecture, APIs, execution flows. Built on a knowledge graph — symbols, call chains, community detection — not just file summaries. doc0 understands how your code actually works.
- Auto-detected API reference (OpenAPI + code analysis)
- "How It Works" pages from cross-module execution flows
- Architecture diagrams with Mermaid
- Changelog generated from git history and PRs
See what doc0 generates for open-source projects like Next.js, Supabase, and Tailwind CSS — then try it on your own repo.
Always current.
Docs that update when your code does
No more stale documentation. Push code, docs update. Edit a page, your changes stick.
Automatic updates
Push to GitHub. doc0 diffs your files, traces provenance to find affected pages, and regenerates only those. Full docs in minutes — incremental updates in seconds.
Editable pages
Edit any generated page with the built-in WYSIWYG editor. Your changes are preserved — regeneration won't overwrite them.
Version history
See what changed and when. Restore previous versions if needed. Full audit trail of your documentation.
AI-native.
Give your AI tools direct access to your docs
Your documentation isn't just for humans. It's structured for AI coding tools — Claude Code, Cursor, Windsurf, and any LLM-powered workflow.
MCP Server
AI tools query your docs directly. Search, list pages, read content — all through the Model Context Protocol.
llms.txt
Standard format for LLM consumption. Your docs are ready for any AI tool that supports the llms.txt specification.
Copy as Markdown
One-click copy for any page. Paste directly into your AI chat, PR description, or knowledge base.
Enterprise-ready security.
Your source code stays yours
Built for teams that care about security. Your code is processed, not stored.
Source code never stored
Code is analyzed in memory during generation, then deleted. It never touches our database. Never used for training.
Access controls
Private projects, publish/unpublish per doc mode, team member management with role-based permissions.
API key management
Generate and revoke MCP access keys. You control exactly who and what can query your documentation.
Audit logging
Every action is logged — project creation, generation runs, team changes, API key rotations. Full audit trail for your records.
