Build fast, elegant, and customizable documentation sites from Markdown and MDX content.

Folio is a file-based documentation engine for Markdown and MDX content. It combines Vite, Tailwind CSS v4, server-rendered pages, syntax highlighting, and a customizable navigation theme. The content can document any project, library, API, or product.

What you get

  • File-based MDX routes from the docs/ directory.
  • Automatic sidebar categories and page navigation.
  • Static production builds with server-rendered content.
  • Customizable themes, layouts, components, and design tokens.
  • A local, copy-paste-owned default theme that can be customized in every generated project.
