Fumadocs

Fumadocs is a React.js framework designed specifically for building documentation websites. It provides developers with the tools to create custom, feature-rich docs using familiar technologies like Markdown and MDX. You can write content in simple Markdown, embed interactive React components with MDX, and even pull in live data from databases or APIs directly into your pages. The goal is to make it easy to build a docs site that fits your project's exact needs and style.

What sets Fumadocs apart is its composable, headless architecture. It's built as separate layers for content, core logic, and UI, which means you can use as much or as little of the framework as you want. It works with popular React frameworks like Next.js, Tanstack Start, and React Router. The framework includes features like syntax-highlighted code blocks, auto-generated tables of contents, callouts, and even special integrations for creating interactive component playgrounds or documenting OpenAPI specifications.

This tool is ideal for developers and teams who need to publish technical documentation, API references, or component libraries. It's used by startups and open-source projects to create clean, maintainable docs. If you're tired of rebuilding your docs from scratch for each project or wrestling with rigid templates, Fumadocs gives you the flexible building blocks to create a documentation site that works your way.
