Overview
Fumadocs is a React.js documentation framework built around Markdown and MDX. It is split into separate packages — fumadocs-mdx for content, fumadocs-core as a headless library and fumadocs-ui for the interface — so it can be adopted whole or used as a library. It ships adapters for Next.js, Tanstack Start, React Router and Waku, and reads content from MDX files, Content Collections or a CMS.
- Best for
- Developers building documentation sites for React apps who want to customise the UI themselves.
- Pricing
- No prices are shown; the pages state Fumadocs is fully open source and available on GitHub, funded by sponsors.
- Runs on
- CLI
Strengths and trade-offs
Strengths
- Official support for Next.js, Tanstack Start, React Router and Waku
- Headless mode to plug in your own UI, or use the bundled themes
- Markdown and MDX with Shiki highlighting, callouts and code tabs
- Open source on GitHub; CLI scaffolds a project in one command
Trade-offs
- React only; no support for non-React stacks is stated
- Configuration and prior knowledge needed — hence the separate Fumapress
- Community-run: maintenance depends on contributors and sponsors

How this score is made up
Each dimension is scored out of 100 and combined into the headline score using fixed weights.
MCP support
Whether an agent can drive the product through the Model Context Protocol, and how much setup that takes.
API quality
Public API surface: machine-readable spec, official SDKs, documented auth, errors, rate limits and versioning.
Documentation
Publicly reachable docs — coverage, freshness, code samples and machine readability.
Agent friendliness
How readable the site is to an automated client: llms.txt, structured data, server-rendered content, crawler access.
Changelog
A public, dated record of what shipped and when — the clearest signal that a product is still alive.
Marketing site structure
Whether the site answers a buyer's questions: clear positioning, the pages that matter, and accessibility.
Page speed
How fast the site loads for real visitors: Chrome UX Report 75th-percentile LCP, INP and CLS, with a Lighthouse mobile run standing in where a site has too little traffic for field data.
Operational trust
Status page and incident history, security disclosure, compliance and data-processing documentation.
Measured, but not part of the score
Useful to know, but not a mark for or against the product — so these do not affect the ranking.
Openness
Source availability, self-hosting, data export and open standards. Scored and shown, but not part of the composite — paid SaaS is not worse for being paid SaaS.
Maintenance
Release cadence and repository activity. Scored and shown, but not part of the composite — it is only measurable for open repositories.
