What 0docs is
0docs is an open-source, self-hosted documentation platform released under the MIT License. Its editor organizes documentation into pages, sections, and blocks, with options such as callouts, steps, code tabs, cards, accordions, and API endpoints. Users can customize colors, fonts, the sidebar, and block styles, then snapshot documentation as versions, publish it, and use a custom domain. An “Ask docs” feature answers questions using published documentation and requires an OpenAI API key; a compatible base URL override is also documented. AI clients can use its built-in MCP endpoint to read and edit documentation, with per-project tokens or anonymous read-only access. 0docs requires PostgreSQL, with uploaded media stored there by default or in S3-compatible storage. Local installation requires Node.js 20+ and pnpm, plus Docker Compose or PostgreSQL 14+. SMTP is optional, but without it password-reset and invitation links are printed to server logs. The default upload maximum is 20 MB per upload. The self-hosting guide recommends HTTPS, database backups, and production configuration.
