Docusaurus is Meta's open-source documentation framework built with React. It generates fast static sites with built-in support for versioning, i18n, search, and MDX. Thousands of open-source projects use it, including React, Jest, and many others.
It is completely free and self-hosted — you deploy to any static hosting provider like Vercel, Netlify, or GitHub Pages. The tradeoff is that you manage the infrastructure and customization yourself, which requires developer involvement.

- Large community with extensive plugin ecosystem
