0docs vs Mintlify

0docs is a free, open-source documentation platform that teams can self-host to create, style, version, and publish documentation. Its MIT-licensed editor arranges content into pages, sections, and blocks such as callouts, steps, code tabs, cards, accordions, and API endpoints. Users can change colors, fonts, sidebar presentation, and individual block styles, then publish documentation snapshots using a custom domain. The “Ask docs” feature answers questions from published documentation and requires an OpenAI API key; an OpenAI-compatible base URL override is documented. AI clients can use a built-in MCP endpoint to read and edit documentation with project tokens or anonymous read-only access. The platform requires PostgreSQL, storing uploaded media there by default or in optional S3-compatible storage. Local installation calls for Node.js 20+ and pnpm, plus Docker Compose or PostgreSQL 14+. The default upload maximum is 20 MB per upload. SMTP is optional, but without it password-reset and invitation links appear in server logs. The self-hosting guide recommends HTTPS, database backups, and production configuration.

Mintlify is a documentation and knowledge platform built for developers and AI agents. Its GitHub App deploys documentation when repository changes are pushed, and its API playground can be generated from OpenAPI or AsyncAPI schemas. Mintlify also generates a search MCP server that lets AI clients such as Claude, Cursor, Goose, and ChatGPT search and retrieve site content. Documentation sites can embed Intercom or Front support widgets through the integrations field in docs.json. The collaborative editor is intended for contributors across engineering, product, customer support, marketing, and writing. Starter costs nothing and includes five editor seats, a custom domain, web editor, authentication, MCP server, and API playground. Pro costs $450 a month, billed monthly, and includes unlimited editor seats, 10,000 credits per month, and $0.01 per credit in overages. Mintlify Desktop is in beta for macOS, Windows, and Linux, with stated minimum operating-system requirements. Mintlify says sensitive organizational and user data is encrypted at rest with AES256-GCM and that it responds to support requests within two business days.
