Docusaurus
by Meta Open Source / React team · Framework
React-based static site generator from Meta for documentation sites with MDX content, versioning, localization and a plugin architecture
Overview
Docusaurus is a static site generator maintained by Meta Open Source and released under the MIT license. It is built on React and renders documentation written in Markdown or MDX, which allows React components to be embedded in pages. The default preset includes a documentation section with sidebars, a blog, a landing page, client-side search integration, dark mode and a theme that can be swizzled (overridden component by component).
Two features distinguish it from Markdown-only generators: documentation versioning, which snapshots the docs for each release, and internationalization, which produces one site per locale from translated files. Docusaurus is widely used for open-source project sites and developer portals, and deploys as static files to GitHub Pages, Vercel, Netlify or any web server. The trade-offs are those of a JavaScript framework: it requires Node.js and a build step, build times grow with large sites, and customizing beyond the theme means writing React. It is not a fit for projects that want to avoid a JavaScript toolchain.

Typical workflows
- Publish a versioned developer portal for a library
- Translate documentation into several languages
- Embed interactive React demos inside docs pages
Strengths
- Versioning and localization built in
- React ecosystem for customization
- MIT license
Limitations
- Requires Node.js and a build toolchain
- Build times increase with large sites
- Customization beyond theming requires React
Prerequisites
- Node.js and a package manager
Who it is for
- Open-source maintainers
- Developer relations and documentation teams
Alternatives & comparison
MkDocs and Sphinx are Python generators with lighter toolchains and strong API-reference support; Docusaurus wins on interactive content, versioning and localization. Next.js is a general web framework that can host documentation but requires building the documentation features yourself.
