Mintlify vs Fumadocs
OCT 2026 auditA comparison of Mintlify and Fumadocs built from values read directly from each provider's own documentation, with the source recorded against every figure.
inetGeek's documentation at inetgeek.com/docs is built with Fumadocs. This record was written by the people who use it, and nothing below is sourced differently because of that: every figure comes from Fumadocs' own site and documentation like every other record here, and where those pages are silent the cell is empty.
The short answer
Choose Mintlify if…
A team that wants docs and an API reference built from Markdown, MDX and OpenAPI files in a git repository, with an AI assistant, llms.txt and an MCP server, at a flat price per account rather than per seat. Pro is $540 a month billed monthly with unlimited editors; the free Starter plan allows five.

Choose Fumadocs if…
A team that already builds in React or Next.js and wants to own its documentation site: Fumadocs is an open-source framework you deploy yourself, with an OpenAPI reference and playground, llms.txt and MCP integrations, and no paid plan.

Consider something else if…
- Mintlify: You want SDKs generated from the same spec. Mintlify shows SDK code samples and points to Speakeasy for the SDKs themselves, where Fern generates them. The AI assistant is a Pro feature and is not on the free plan.
- Fumadocs: You want someone to host and run it. Fumadocs sells no hosting, so deploying and keeping the site up is your work, SDK generation is not described, and its AI assistant needs a model you supply.

When these numbers change, hear about it. Sources are re-checked monthly; a repricing goes out as a short note.
Documented by only one.
These criteria are published by one provider and not the other. An absence here means we have not found a source, not that the feature is missing — except where we say we read the other provider's own page on a given date and it does not state it. Those rows lean, and the provider can correct them with a link.
