# Mintlify against GitBook on what an agent reads

In short

Mintlify hosts an llms.txt at the root of every docs project, lists every page, and keeps it current without maintenance; a custom llms.txt can replace it. Mintlify leads on llms.txt linking, 2 to 1; GitBook: The docs page links the files; a home page or header link by default is not documented.

## The sourced difference

Mintlify answers Accept: text/markdown on the page URL and advertises llms.txt in an HTTP Link header on every response; GitBook documents the .md suffix, llms.txt, llms-full.txt and a per-site MCP server, but not header negotiation or a Link header on its LLM-ready docs page.

## The rubric side by side

| Key | Mintlify | GitBook |
| --- | --- | --- |
| Content in the initial HTML | 2, on by default | 2, on by default |
| Real status codes | 2, on by default | 2, on by default |
| llms.txt generation | 2, on by default | 2, on by default |
| llms.txt linking | 2, on by default | 1, with setup |
| Markdown on request | 2, on by default | 1, with setup |
| JSON-LD output | 1, with setup | 0, not offered |
| OpenAPI exposure | 2, on by default | 1, with setup |
| Fenced, tagged code | 2, on by default | 2, on by default |
| Total | 15 of 16 | 11 of 16 |

The two differ on 4 of the numeric keys: llms.txt linking, markdown on request, JSON-LD output, OpenAPI exposure. Evidence for each score is on the profiles of [Mintlify](https://agentreadyhtml.com/platforms/mintlify/) and [GitBook](https://agentreadyhtml.com/platforms/gitbook/).

## Verdicts by reader

Technical SEO

Mintlify gives a crawler more ways to find the agent files without guessing paths.

Docs owner

Both generate the files with no work; pick GitBook if an MCP endpoint per site matters more than headers.

Front-end developer

Mintlify needs no edge code for negotiation; on GitBook you rely on the .md URLs.

## What each leaves undone

### Mintlify

-   Does not publish the llms.txt behind a fully authenticated site to tools that cannot sign in.
-   Does not cap llms-full.txt size; the 100,000 character split applies to llms.txt only.

### GitBook

-   Does not exclude hidden pages from llms-full.txt or the MCP server.
-   Does not document Accept-header negotiation on the LLM-ready docs page.

Work left to the developer: Mintlify, Low: write a description in each page frontmatter so llms.txt entries carry one. GitBook, Low: nothing to switch on; check hidden pages before publishing, since they appear in llms-full.txt.
