Mintlify vs GitBook: the honest comparison

The short answer

Edition v2026.Q3 · pricing and status verified 2026-08-06.

Choose Mintlify for the default docs element for an AI-led startup — agent-readable by default (llms.txt, .md routes, hosted MCP), with the data to prove agents actually use it. Choose GitBook for teams where PMs, support, and engineers all edit docs — visual editor plus Git sync, with llms.txt and an MCP server on every tier including free.

On the elems table, Mintlify holds seat #1 of the Docs & Help element and GitBook holds #2 — this is the closest call in the category, and the honest answer depends on which trade-off you can live with.
