The short version

  • Each has a real cost: Fumadocs it is a library rather than a finished theme, so the initial setup is meaningfully longer than a generator that ships a working site from one command.; Mintlify starter plan excludes webhooks, analytics, and integrations, pushing most teams toward the $450/month Pro tier
  • They diverge on capability: Fumadocs covers Next.js App Router native, Mintlify covers Web editor.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Fumadocs

  • It is a library rather than a finished theme, so the initial setup is meaningfully longer than a generator that ships a working site from one command.
  • Maintenance is concentrated in a very small group, so an unresponsive week is a blocked upgrade and there is no support contract to escalate to.
  • It only targets Next.js, so adopting it commits the documentation to that framework and a later migration means rewriting the site rather than swapping a theme.
  • Breaking changes have arrived across minor versions during rapid development, so pinning versions and reading migration notes is a recurring cost rather than a one off.
  • Running docs inside the application means docs traffic hits your application infrastructure and shares its failure modes, where a separate static site would have stayed up.

Mintlify

  • Starter plan excludes webhooks, analytics, and integrations, pushing most teams toward the $450/month Pro tier
  • Pro plan AI credits are metered with per-credit overage charges, making costs variable for heavy agent usage
  • Jump from free Starter to Pro is a large price step with no mid-tier option
  • Enterprise features like SSO and SLAs require contacting sales rather than transparent pricing

Answered from the vendors’ own pages

Fumadocs: Can I put documentation behind authentication?

Yes. Pages are Next.js server components, so the same session and authorisation checks the rest of the application uses apply.

Mintlify: Is there a free plan for Mintlify?

Yes, the Starter plan is free with no credit card required, offering 5 editor seats, custom domain hosting, the web editor, authentication, MCP server, and an API playground.

Source
Fumadocs: Does it work outside Next.js?

No. The UI layer depends on the Next.js App Router.

Mintlify: What does the Pro plan cost and include?

Pro costs $450/month (or discounted annually) with unlimited editor seats plus the AI Agent, Assistant, Automations, preview deployments, and admin APIs.

Source
Fumadocs: Can it generate pages from an OpenAPI spec?

Yes, including operation pages, schema rendering and an interactive request playground.

Mintlify: How are AI credits metered?

Pro includes 10,000 AI credits per month consumed by the Assistant, Agent, and Automations, with overage billed at $0.01 per credit; additional credit packs can be purchased.

Source
Fumadocs: Who maintains it and is that a risk?

A very small maintainer group. For a long lived commercial documentation set, treat the low bus factor as a real risk and budget for owning a fork.

Mintlify: What do new users get to try AI features?

New users receive their first month of AI credits free, letting them try the Agent and Assistant before being billed for usage.

Source
Fumadocs: Do I still need a separate docs deployment?

No, and avoiding one is the main reason to choose it. The cost is that docs share your application uptime.

Mintlify: What does Enterprise add over Pro?

Enterprise adds SSO, SCIM, RBAC, a performance SLA, advanced insights, enterprise-grade security and legal terms, and migration support, priced via custom sales contact.
