- Developers who want a customizable docs framework rather than a hosted service
Choose shadcn/ui if you need…
- Developers building React or Next.js interfaces who want full control over component code
- Teams that want a consistent design system they can change freely
- Designers working with developers who need components that match a custom look
- Projects already using Tailwind CSS, which the topics list suggests is the styling base

What each one is
Fumadocs
Fumadocs is an open-source framework for building documentation websites with React.js frameworks and Astro. It is meant to be used as a toolkit inside a developer's own project rather than as a finished, ready-made site. The README lists Next.js, Astro with React, and several Vite-based options (TanStack Start, Waku, React Router) as officially supported.
shadcn/ui
shadcn/ui is a collection of UI components (buttons, forms and similar pieces) that you add to your own project as source code rather than installing as a locked package. You can then edit, extend and restyle them. The README describes it as a starting point for building your own component library.
Best for

- React developers who want to build a documentation site
- Teams already using Next.js or Astro who want docs in the same stack
- Developers who want a customizable docs framework rather than a hosted service
shadcn/ui
- Developers building React or Next.js interfaces who want full control over component code

Strengths
Fumadocs
- Supports several popular React frameworks and Astro according to the README
- Documentation is available on the project's homepage at fumadocs.dev
- Released under the permissive MIT license
shadcn/ui
- Component code lives in your project, so you can change it without waiting on an upstream release
- The README states the components are open source and MIT licensed
- Large community interest, with over 120,000 stars on GitHub
Not ideal for
Fumadocs
- People who want a no-code documentation tool, since it requires writing React code
- Projects on frameworks not listed as officially supported, since the README only names the supported ones
- Users who need CommonJS-only environments, because the README says all packages are ESM only
shadcn/ui
- People who want a finished, unstyled-free app or website template; this is a set of building blocks
- Developers who do not use React, since the topics point to a React-focused stack
- Beginners without basic web development knowledge, as adapting components requires reading code
Trade-offs
Fumadocs
- All packages are ESM only, which may cause friction with older tooling
- Requires familiarity with React and a JavaScript framework to use
- The README provided is truncated, so detailed setup and feature information was not available to verify
shadcn/ui
- Because you own the code, you are responsible for updating components yourself
- The README provided is short, so detailed setup and feature information lives on the external docs site
- Relies on a specific stack (React and Tailwind) as indicated by the topics, which limits use elsewhere
