Docusaurus
React-based documentation site generator by Meta (Facebook). Docusaurus builds feature-rich documentation sites from Markdown/MDX files with versioning, internationalization (i18n), full-text search (Algolia), and plugin system. Powers hundreds of major open-source projects including React, Jest, Babel, Redux, Prettier. Strong on versioned documentation, blog functionality, and multi-language docs.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
MIT open source from Meta. Static site with minimal attack surface. React's XSS protection applies to MDX. No server-side execution in production.
⚡ Reliability
Best When
You're building versioned, multi-language documentation for a developer product with React expertise in the team — especially for open-source projects.
Avoid When
Your team uses Vue, you have simple documentation needs (use VitePress), or you want managed hosting with minimal setup (use Mintlify or GitBook).
Use Cases
- • Build versioned agent API documentation that maintains separate docs for each SDK version with migration guides
- • Create multi-language documentation sites using Docusaurus's built-in i18n support for international agent SDK docs
- • Generate documentation with interactive code blocks (live MDX) that execute agent SDK examples in the browser
- • Build open-source project documentation with Docusaurus's blog + docs combination site structure
- • Integrate Algolia DocSearch for full-text search across large agent documentation with faceted filtering
Not For
- • Teams preferring Vue or non-React stacks — VitePress or Nuxt Content are better for Vue teams
- • Simple small documentation needs — VitePress or Mintlify are simpler for small documentation sites
- • Marketing sites or complex applications — Docusaurus is documentation-specific; use Next.js for general-purpose sites
Interface
Authentication
No built-in auth — static site. Private docs require hosting-level auth (Netlify password, Cloudflare Access, etc.).
Pricing
MIT open source from Meta. Free forever.
Agent Metadata
Known Gotchas
- ⚠ Docusaurus uses webpack for builds (not Vite) — build times are slower than VitePress for large documentation; hot reload is slower in development
- ⚠ MDX in Docusaurus 3.x uses MDX 3 — older MDX 1.x syntax may not work; JSX expressions directly in Markdown may need adjustment for MDX 3 compatibility
- ⚠ Versioned docs require careful management — version snapshots are stored in versioned_docs/ directory; agents managing documentation versions must follow Docusaurus's versioning workflow
- ⚠ Docusaurus plugins execute in a Node.js build environment — plugins using browser APIs require SSR handling or must be wrapped in BrowserOnly components
- ⚠ Algolia DocSearch requires crawler configuration and separate Algolia account — built-in search is local-only; production search requires Algolia setup
- ⚠ i18n translation requires maintaining separate locale folders — agents adding internationalization must generate translation files and maintain them in sync with source docs
