Docusaurus Has a Free Documentation Framework — Beautiful Docs Sites from Markdown

Docusaurus is a documentation framework by Meta that turns Markdown into beautiful websites.

What You Get for Free

• Markdown/MDX — write docs in Markdown with React components
• Versioning — version your docs alongside your code
• Search — Algolia DocSearch (free for open source)
• i18n — built-in internationalization
• Blog — integrated blog with RSS
• Dark mode — automatic light/dark theme
• Plugin ecosystem — API docs, diagrams, analytics plugins
• SEO — automatic meta tags, sitemaps, canonical URLs
• MDX — embed React components in Markdown
• Deploy anywhere — static site, works on GitHub Pages, Vercel, Netlify

Quick Start

npx create-docusaurus@latest my-docs classic
cd my-docs && npm start

# Write docs in docs/ folder as Markdown
# Customize sidebar in sidebars.js
# Deploy to GitHub Pages with one command
npm run deploy

Why Teams Choose It

GitBook charges $8/user/month. ReadMe is expensive for startups:

• Free forever — static site, free hosting on GitHub Pages
• MDX — interactive components in docs (not just static text)
• Versioning — docs per software version
• Used by Meta — React, Jest, Relay all use Docusaurus

A startup was paying $40/mo for GitBook for 5 team members. They switched to Docusaurus on GitHub Pages — better-looking docs, version support, custom React components, and zero hosting cost.
