Fumadocs is a documentation framework based on Next.js, designed to be fast, flexible, and compose seamlessly into the Next.js App Router.

Fumadocs handles core logic including document search, content source adapters, and Markdown extensions.

The default Fumadocs theme provides a polished visual design with interactive components for documentation sites.

Fumadocs supports Markdown and MDX out-of-the-box, where MDX is a superset of Markdown with JSX syntax allowing component imports and value exports within documents.

Fumadocs is intentionally non-opinionated and designed to be customizable — described by its creator as 'a framework that you can break.'

Fumadocs uses less abstraction than typical documentation frameworks, expecting developers to write code and integrate with their existing software rather than relying on configuration files alone.

Fumadocs provides utilities and a good-looking UI while preserving full access to Next.js App Router features such as Static Site Generation.

A quick-start / agent-skills documentation page is reachable at https://trellis2.app/docs/api/quickstart.

Agent-native positioning with a concrete operational path: "The docs provide a concrete API quickstart with curl commands and endpoints for agents to integrate, demonstrating an operational path for AI agents.".

Fumadocs supports Markdown and MDX out-of-the-box, where MDX is a superset of Markdown with JSX syntax allowing component imports and value exports within documents.

Fumadocs is renderer-agnostic beyond MDX — developers can use any renderer such as next-mdx-remote or CMS integrations as alternative content pipelines.

Fumadocs is fully compatible with Next.js static export, allowing the entire documentation site to be exported as static HTML without requiring a Node.js server at runtime.

Fumadocs search functionality is powered by remote servers, enabling static export to work without additional search configuration.

The entry page was fetched and analyzed for machine-interface signals (title, headings, developer links, keyword probes).

llms.txt is published at the site root and readable.

sitemap.xml is reachable and lists site pages.

A documentation surface is reachable at https://trellis2.app/docs.

A machine-readable OpenAPI/Swagger specification is published at https://trellis2.app/api/openapi.json.

Fumadocs supports multiple content sources with officially maintained source adapters, letting developers choose their preferred content backend.

The creator acknowledges Fumadocs is less powerful than Mintlify for certain integrations such as OpenAPI, and does not recommend switching from Mintlify for users satisfied with their current setup.
