Try one workflow before switching
Move one endpoint reference and its example request. Make a small schema change and check how it reaches the published docs. Verify which credentials and sample data are appropriate to expose.
Choose by the job you need to preserve
This is ReadMe the developer-documentation platform, not a README file. Mintlify and GitBook are hosted candidates; Docusaurus is a framework to maintain yourself. Compare the API explorer, authenticated examples and versioning before moving a developer portal.
Try one representative workflow
Publish one OpenAPI operation with authentication and a code sample, then verify the reference links and first-request instructions.
Run a small migration before committing
Import a spec with one authenticated endpoint, an error response and two API versions. Run the example using a disposable test token. Verify that no example publishes a real credential and that the old API URL redirects to the intended version.
What to include in the price comparison
Include API-reference features, custom domains, contributors, search and assistant usage in the comparison. A framework can reduce platform fees while increasing engineering work. Keep those costs separate from a hosted plan quote.
What the documented AI features actually cover
Mintlify documents an assistant that cites documentation sources. GitBook also offers an embedded assistant. Check plan availability and how versioned or restricted pages are handled before enabling answers for API customers.
How to use this comparison
Run the same small workflow in your shortlisted products: keep the input, output and required integration the same. The table records documented scope; it does not report a side-by-side product test.

Are all of these apps AI-built?
Only entries with an original maker record carry that attribution. Established products are listed separately and are not assigned an AI-build label.
Sources & maker notes
The AI-build attribution applies only to products with a linked maker record. Other options use the publisher’s current product documentation; prices and plans should be checked at the source.
