The price models read are open source, free, quote and subscription. On AR-READ-09 (Advertise a markdown mirror), of the six docs tools read on it, three meet it by default, two need a setting, plugin or code and one has no statement. ## The 11 docs tools The eleven docs tools are Docusaurus, Fern, GitBook, Material for MkDocs, Mintlify, Read the Docs, ReadMe, Redocly, Scalar, Starlight and VitePress. On CF-MARKDOWN-NEGOTIATION (Markdown by Accept), of the eleven docs tools read on it, two meet it by default, one needs a setting, plugin or code and eight have no statement. Three of them have a platform count in the crawl, 5 home pages between them, counted from headers and generator tags. The home domain of one of them is in the crawled top 10,000, so its own site has a crawl row. | Vendor | What it does for this layer | Standards supported | Pricing model | Own check or score | Last read | | --- | --- | --- | --- | --- | --- | | Docusaurus | Docusaurus is Meta's MIT-licensed React static site generator for documentation; the classic preset builds HTML pages with a sitemap by default, and agent files such as llms.txt come from static files or community plugins. | 4 of 11 read; AR-FIND-01, AR-FIND-03, AR-READ-01, AR-READ-05; 5 partial, 2 no statement | open source | Cloudflare scan 7 of 100; 2026-11-05; 2 of 5,897 home pages counted, 2026-11-04 | 2026-11-05 | | Fern | Fern generates API documentation sites and SDKs from an API definition; its docs sites publish llms.txt, a markdown version of every page and, with Ask Fern enabled, a hosted MCP server. | 4 of 7 read; AR-READ-06, AR-READ-07, AR-READ-09, AR-ACT-02; 1 partial, 2 no statement | free, on request | Cloudflare scan 27 of 100; 2026-11-05 | 2026-11-05 | | GitBook | GitBook is a hosted documentation platform whose published sites get llms.txt, a markdown version of every page, Accept-header markdown and an MCP server automatically. | 6 of 9 read; AR-FIND-01, AR-FIND-03, AR-READ-07, AR-READ-09, AR-ACT-03, CF-MARKDOWN-NEGOTIATION; 1 partial, 2 no statement | free, subscription | 8 of 10 crawl checks pass; 2026-11-04 | 2026-11-05 | | Material for MkDocs | Material for MkDocs is an MIT-licensed theme for the Python static site generator MkDocs that builds static HTML documentation; its maintainers put it into maintenance mode in favour of their successor, Zensical. | 1 of 5 read; AR-READ-01; 0 partial, 4 no statement | open source, other products: no price read | no score | 2026-11-05 | | Mintlify | Mintlify is a hosted documentation platform that generates llms.txt, llms-full.txt, markdown copies of every page, JSON-LD and a search MCP server for each docs site by default. | 7 of 9 read; AR-FIND-01, AR-FIND-03, AR-READ-07, AR-READ-08, AR-READ-09, AR-ACT-03, CF-MARKDOWN-NEGOTIATION; 1 partial, 1 no statement | free, subscription | Cloudflare scan 47 of 100; 2026-11-05; 1 of 5,897 home pages counted, 2026-11-04 | 2026-11-05 | | Read the Docs | Read the Docs builds and hosts documentation from any tool that outputs HTML (Sphinx, MkDocs and others), and generates a sitemap.xml and a default robots.txt for every project. | 4 of 8 read; AR-FIND-01, AR-FIND-03, AR-READ-01, AR-READ-02; 1 partial, 3 no statement | free, subscription | Cloudflare scan 27 of 100; 2026-11-05 | 2026-11-05 | | ReadMe | ReadMe is a hosted API documentation platform with llms.txt on by default and AI discoverability toggles for markdown negotiation, Link headers, an RFC 9727 API catalog, an MCP server and its server card. | 4 of 10 read; AR-FIND-01, AR-FIND-03, AR-READ-07, AR-ACT-02; 5 partial, 1 no statement | free, subscription | Cloudflare scan 33 of 100; 2026-11-05 | 2026-11-05 | | Redocly | Redocly turns OpenAPI descriptions into hosted reference docs, an MCP server for the docs and SDKs, and maintains the open-source Redoc renderer and Redocly CLI. | 2 of 5 read; AR-ACT-02, AR-ACT-03; 1 partial, 2 no statement | subscription, open source | Cloudflare scan 40 of 100; 2026-11-05 | 2026-11-05 | | Scalar | Scalar publishes an open-source OpenAPI reference renderer and a hosted platform for API docs, SDKs and MCP servers generated from OpenAPI documents. | 1 of 4 read; AR-ACT-02; 1 partial, 2 no statement | free, subscription, open source | Cloudflare scan 80 of 100; 2026-11-05 | 2026-11-05 | | Starlight | Starlight is the documentation theme and integration of the Astro project, MIT-licensed, that builds static HTML docs with a sitemap once the site URL is set. | 2 of 6 read; AR-READ-01, AR-READ-05; 1 partial, 3 no statement | open source | Cloudflare scan 7 of 100; 2026-11-05 | 2026-11-05 | | VitePress | VitePress is an MIT-licensed Vue and Vite static site generator for documentation that prerenders every page to HTML and has a built-in sitemap option. | 2 of 7 read; AR-READ-01, AR-READ-05; 1 partial, 4 no statement | open source | Cloudflare scan 27 of 100; 2026-11-05; 2 of 5,897 home pages counted, 2026-11-04 | 2026-11-05 | ## Sources - [docusaurus.io](https://docusaurus.io)read 2026-11-05 - [buildwithfern.com](https://buildwithfern.com)read 2026-11-05 - [gitbook.com](https://www.gitbook.com)read 2026-11-05 - [squidfunk.github.io/mkdocs-material/](https://squidfunk.github.io/mkdocs-material/)read 2026-11-05 - [mintlify.com](https://www.mintlify.com)read 2026-11-05 - [about.readthedocs.com](https://about.readthedocs.com)read 2026-11-05 - [readme.com](https://readme.com)read 2026-11-05 - [redocly.com](https://redocly.com)read 2026-11-05 - [scalar.com](https://scalar.com)read 2026-11-05 - [starlight.astro.build](https://starlight.astro.build)read 2026-11-05 - [vitepress.dev](https://vitepress.dev)read 2026-11-05 Last reviewed 2026-11-05.
