How we chose these Mintlify alternatives

We looked for open-source tools that overlap with Mintlify's core: building and publishing documentation sites with good search, API references, and a pleasant editing experience. We verified each project's license, recent activity, stars, and hosting in its repository. Mintlify is a hosted product, so we compare frameworks you deploy yourself with platforms that also offer hosting. See our methodology for the full criteria.

Important: these are frameworks and tools, not a hosted product

Fumadocs and xyd are frameworks you build and deploy yourself, and Fumadocs requires Next.js. Scalar focuses on interactive API documentation from OpenAPI and also offers a hosted option. Vrite is a technical writing platform for collaborative content rather than a docs site generator.

Closest to Mintlify

Scalar is the closest for API documentation, with an interactive API reference and a hosted option. Fumadocs is the closest for general documentation sites, with MDX content, built-in search, and customizable components, and xyd combines docs with hot reloading, TypeScript support, and API docs generation.

Important: licenses are mixed

Scalar's core is MIT, and some parts around it, such as hosted features, may be commercial. Fumadocs and xyd are MIT. Vrite's repository is under the AGPL-3.0, MIT, or Elastic License 2.0, depending on the file or directory, with AGPL-3.0 as the default.

Maintenance status

Scalar, Fumadocs, Vrite, and xyd had commits within days of this update. xyd is very young with about 114 stars, so check its maturity first.

Why look for a Mintlify alternative?

Mintlify is a proprietary hosted documentation platform priced by seats and features, with your docs served from its infrastructure. Open-source alternatives let you host documentation anywhere, keep content in your repository, avoid per-seat pricing, and customize the design and components, at the cost of building and maintaining more of the setup yourself.
