The price models read are open source, subscription, free and per seat. On AR-FIND-03 (Sitemap listed in robots.txt), of the ten CMSs read on it, three meet it by default, one needs a setting, plugin or code and six have no statement. ## The 11 CMSs The eleven CMSs are Adobe Experience Manager, Drupal, Ghost, HubSpot Content Hub, Joomla, Payload, Sanity, Storyblok, Strapi, TYPO3 and WordPress. On AR-ACT-03 (MCP over Streamable HTTP), of the seven CMSs read on it, three meet it by default, two need a setting, plugin or code and two have no statement. Seven of them have a platform count in the crawl, 455 home pages between them, counted from headers and generator tags. The home domain of six of them is in the crawled top 10,000, so their own site has a crawl row. | Vendor | What it does for this layer | Standards supported | Pricing model | Own check or score | Last read | | --- | --- | --- | --- | --- | --- | | Adobe Experience Manager Sites | Adobe Experience Manager Sites is Adobe's enterprise CMS; its Edge Delivery Services documentation at aem.live publishes llms.txt, markdown copies of docs pages and a JSON query index for published pages. | 0 of 4 read; 2 partial, 2 no statement | no price read | no score | 2026-11-05 | | Drupal | Drupal is the GPL-licensed PHP CMS that ships a robots.txt file in its scaffold; sitemaps, JSON-LD and AI agent features come from contributed modules such as the AI module. | 1 of 8 read; AR-FIND-01; 2 partial, 5 no statement | open source | 4 of 10 crawl checks pass; 2026-11-04; 141 of 5,897 home pages counted, 2026-11-04 | 2026-11-05 | | Ghost | Ghost is an MIT-licensed Node.js publishing platform that adds XML sitemaps, metadata and structured data to every post and page automatically. | 2 of 6 read; AR-FIND-03, AR-READ-08; 0 partial, 4 no statement | open source, subscription | 5 of 10 crawl checks pass; 2026-11-04; 2 of 5,897 home pages counted, 2026-11-04 | 2026-11-05 | | HubSpot Content Hub | HubSpot Content Hub is HubSpot's hosted CMS that renders HubL templates on HubSpot servers, keeps an automatic sitemap and an editable robots.txt per domain, and marks its hs-sites system domains noindex. | 3 of 9 read; AR-FIND-01, AR-FIND-03, AR-READ-01; 5 partial, 1 no statement | subscription | 6 of 10 crawl checks pass; 2026-11-04; 37 of 5,897 home pages counted, 2026-11-04 | 2026-11-05 | | Joomla | Joomla is a GPL-licensed PHP CMS that ships a robots.txt.dist file that disallows its system folders, including /api/, for every user agent. | 0 of 6 read; 2 partial, 4 no statement | open source | 4 of 10 crawl checks pass; 2026-11-04; 3 of 5,897 home pages counted, 2026-11-04 | 2026-11-05 | | Payload | Payload is an MIT-licensed TypeScript headless CMS that installs into a Next.js app; Figma acquired the company in June 2025 and says Payload remains open source. | 0 of 3 read; 0 partial, 3 no statement | open source | Cloudflare scan 20 of 100; 2026-11-05 | 2026-11-05 | | Sanity | Sanity is a headless content platform queried with GROQ; it runs a hosted MCP server at mcp.sanity.io that lets AI agents query, patch and release content, while the public HTML comes from the front end. | 2 of 5 read; AR-ACT-01, AR-ACT-03; 0 partial, 3 no statement | free, per seat | 7 of 10 crawl checks pass; 2026-11-04 | 2026-11-05 | | Storyblok | Storyblok is a headless CMS with a visual editor that delivers content over APIs to any front end; its docs list a CLI and an MCP server that lets an AI client work in a space. | 2 of 5 read; AR-ACT-03, AR-ACT-06; 0 partial, 3 no statement | free, subscription | Cloudflare scan 20 of 100; 2026-11-05 | 2026-11-05 | | Strapi | Strapi is an open-source headless Node.js CMS that serves content over REST and GraphQL APIs to a separate front end, with a generally available MCP server that exposes content types to agents. | 1 of 5 read; AR-ACT-03; 0 partial, 4 no statement | open source, subscription | Cloudflare scan 20 of 100; 2026-11-05; 1 of 5,897 home pages counted, 2026-11-04 | 2026-11-05 | | TYPO3 | TYPO3 is a GPL-licensed PHP enterprise CMS; its core SEO extension adds meta tag fields and XML sitemaps. | 0 of 5 read; 1 partial, 4 no statement | open source | Cloudflare scan 20 of 100; 2026-11-05; 19 of 5,897 home pages counted, 2026-11-04 | 2026-11-05 | | WordPress | WordPress is the GPL-licensed PHP CMS that renders pages on the server, serves a virtual robots.txt and core XML sitemaps by default, and since 6.9 has an Abilities API that the official MCP adapter exposes to agents. | 4 of 10 read; AR-FIND-01, AR-FIND-03, AR-READ-01, AR-READ-02; 6 partial, 0 no statement | open source | 7 of 10 crawl checks pass; 2026-11-04; 252 of 5,897 home pages counted, 2026-11-04 | 2026-11-05 | ## Sources - [business.adobe.com/products/experience-manager/sites/aem-sites.html](https://business.adobe.com/products/experience-manager/sites/aem-sites.html)read 2026-11-05 - [drupal.org](https://www.drupal.org)read 2026-11-05 - [ghost.org](https://ghost.org)read 2026-11-05 - [hubspot.com/products/content](https://www.hubspot.com/products/content)read 2026-11-05 - [joomla.org](https://www.joomla.org)read 2026-11-05 - [payloadcms.com](https://payloadcms.com)read 2026-11-05 - [sanity.io](https://www.sanity.io)read 2026-11-05 - [storyblok.com](https://www.storyblok.com)read 2026-11-05 - [strapi.io](https://strapi.io)read 2026-11-05 - [typo3.org](https://typo3.org)read 2026-11-05 - [wordpress.org](https://wordpress.org)read 2026-11-05 Last reviewed 2026-11-05.
