Docusaurus

Static site generator optimized for documentation websites. Builds a single-page application with fast client-side navigation, using React and MDX to turn Markdown files into static HTML ready for deployment.

Created by Meta Open Source and trusted by projects like Redux, React Native, Supabase, and Temporal for their official docs. Unlike Gatsby or Next.js, Docusaurus focuses narrowly on documentation and ships versioning, internationalization, and search out of the box. Many open-source projects moved from GitBook to Docusaurus for full control and no vendor lock-in.

Key capabilities:

• MDX-powered content with React components embedded in Markdown
• Document versioning to support multiple release streams
• Built-in internationalization with Crowdin or git-based workflows
• Algolia-powered documentation search
• One-command deploy to GitHub Pages, Netlify, or Vercel

Teams use Docusaurus for API reference sites, product documentation, open-source project wikis, and technical blogs. Developers author content in plain Markdown, benefit from incremental builds and hot reloading, and can extend layouts with custom React components.
