The record

Product: 0docs is an open-source, self-hostable documentation platform with a block-based editor, theming, versioning, and an AI “Ask docs” feature.
License: The project is released under the MIT License.
Block editor: The editor supports blocks including callouts, steps, code tabs, cards, accordions, and API endpoints.
Publishing: Users can snapshot documentation as versions, publish it, and use a custom domain.
AI feature: The “Ask docs” feature is enabled by setting an OpenAI API key, and the repository also documents an OpenAI-compatible base URL override.
Agent integration: 0docs provides a built-in MCP endpoint that AI clients can use to read and edit documentation, with per-project tokens or anonymous read-only access.
Deployment: The project documents deployment on Railway and local installation using Docker and pnpm.
Database: A PostgreSQL database is required, and uploaded media is stored in PostgreSQL by default or can use S3-compatible storage.
Authentication: 0docs includes email and password authentication with server-side sessions, and public signup can be disabled after initial setup.
Upload limit: The documented default maximum upload size is 20 MB per upload.
Email setup: SMTP is optional for password-reset and invite emails; without SMTP, reset and invite links are printed to server logs.
Security operations: The self-hosting guide recommends production HTTPS, PostgreSQL backups, and setting NODE_ENV=production to enable the Secure cookie flag.
Editor: The editor organizes documentation into pages, sections, and blocks, including code, callouts, tabs, cards, steps, and API endpoints.
Theming: Users can customize colors, fonts, the sidebar, and per-block styles.
