If you build with FastAPI, you know the drill. You write your endpoints, add your Pydantic models, and FastAPI auto-generates an OpenAPI spec. That spec is the source of truth for your entire API. So why does Mintlify ask you to rewrite it in MDX?
Mintlify is a powerful documentation platform. It produces beautiful pages. It supports custom guides, tutorials, changelogs, and fully branded doc sites with custom CSS. For teams that need a comprehensive documentation hub — not just API reference, but onboarding guides, conceptual docs, and product changelogs — it is genuinely excellent.
But if what you need is API reference documentation for a FastAPI project, Mintlify introduces a layer of indirection that costs you time and money.
To get your API docs on Mintlify, you write MDX files. You configure a mint.json. You set up a deployment pipeline. You maintain those MDX files every time your API changes. If you are disciplined about it, your docs stay in sync. If you are not — and most teams are not — your docs drift. An endpoint gets added. A parameter changes shape. The MDX files do not update themselves.
DocoAPI skips this entirely. You point it at your FastAPI app's /openapi.json URL or connect your GitHub repo. It reads your OpenAPI spec. It publishes your docs. When you push a new version, the docs update automatically. Setup takes about 10 minutes. There is no MDX to write. There is no config to maintain. The spec is the docs.
Mintlify's Startup plan starts around $150/month. To get AI-powered search — the feature that makes docs genuinely useful instead of a wall of text — you need the Growth plan at $300/month or more. And Mintlify's pricing scales with seats. Add more team members, pay more.
DocoAPI is $99/month. Flat. Every feature included: AI semantic search, interactive playground, spec history with rollback, custom subdomain, and the MCP server. No seat-based pricing. No feature gates. One price.
For a solo developer or a small team running a FastAPI backend, the math is simple. You get the features that matter for API documentation at a third of the cost.
Both DocoAPI and Mintlify offer MCP servers. But they do fundamentally different things.
Mintlify's MCP server lets AI agents search your documentation. An AI assistant can query your docs and get back relevant text. That is useful for context — an LLM can read about your API before writing code against it.
DocoAPI's MCP server lets AI agents call your API endpoints directly. Point Cursor, Claude Code, or Windsurf at yourproject.docoapi.com/mcp and the AI assistant can make real requests to your real API. Not search. Not suggestions. Execute. Your API key never touches DocoAPI's servers — auth passes through in the request header, directly to your API.
This is not an incremental improvement. It is a different category of tool. Mintlify's MCP is a reading assistant. DocoAPI's MCP is an execution assistant.
Mintlify’s MCP is a reading assistant. DocoAPI’s MCP is an execution assistant.
DocoAPI is purpose-built for API reference documentation generated from OpenAPI specs. It does not support MDX content pages. It does not have custom themes, colors, or logos yet. It does not offer guides, tutorials, or changelogs.
If your documentation needs go beyond API reference — if you need onboarding flows, conceptual guides, or a fully branded content hub — Mintlify is the better tool.
If what you need is your FastAPI API reference, published beautifully, synced automatically, searchable by AI, and executable by AI agents — DocoAPI does that for $99/month with zero configuration.
Frequently Asked Questions
Does DocoAPI support MDX or custom content pages like Mintlify?
No. DocoAPI generates API reference documentation directly from your OpenAPI spec. It does not support MDX, custom pages, guides, or tutorials. If you need those, Mintlify is the better choice. DocoAPI is focused specifically on making your API reference beautiful, searchable, and executable.
Both Mintlify and DocoAPI have MCP servers. What is the difference?
Mintlify’s MCP server is search-only — AI agents can query your documentation and get back relevant text. DocoAPI’s MCP server is executable — AI agents can make real API calls to your actual endpoints. With DocoAPI, when you point Cursor or Claude Code at your MCP URL, the AI can test endpoints, create resources, and interact with your API directly. Mintlify’s MCP helps AI understand your API. DocoAPI’s MCP helps AI use your API.
How does DocoAPI’s pricing compare to Mintlify for a small team?
DocoAPI is $99/month flat with all features included, regardless of team size. Mintlify’s Startup plan starts around $150/month and scales with seats. To get AI search on Mintlify, you need the Growth plan at $300/month or more. For a small team that needs API reference docs with AI search, DocoAPI costs roughly a third of what Mintlify charges.
Can I migrate from Mintlify to DocoAPI?
If your Mintlify docs are generated from an OpenAPI spec, migration is straightforward — point DocoAPI at the same spec and your API reference will be published in minutes. However, any custom MDX content (guides, tutorials, changelogs) cannot be migrated to DocoAPI, since DocoAPI only generates docs from OpenAPI specs.
Does DocoAPI support custom branding like Mintlify does?
Not yet. DocoAPI currently provides a clean, professional docs portal at yourproject.docoapi.com, but custom themes, colors, and logos are not available today. This is on the roadmap. Mintlify offers full brand customization including custom CSS, colors, logos, and layouts.
