Vendors behind what an agent reads
In short
74 vendors in six types are profiled here, from 22 frameworks and 18 docs platforms to 12 hosts and CDNs, each read on 5 November 2026. Every profile carries sourced facts, dated prices, six standards and readings of the vendor's own site. 42 names that were not read are listed, and no table sorts by score.
Crawl edition 2026-11-04, page updated 2026-11-05. How the viewer, the index and the scores work.
A company is listed only when its own pages say what it does for the HTML an agent receives, and a name that appears only in a roundup is left out. The names came from the 23 platform profiles on this site, the platform field of the llms.txt Index, the generator tags in the crawl of 13,071 domains, the integrations list on llmstxt.org and the vendors' own pages.
The profiles show 872 sourced facts between them, 713 of them from primary pages and 122 observed on 5 November 2026. Where a limit says what a fact says, a page keeps one of the two, and the downloads keep both. The home page of every vendor was requested once: 71 of the 74 answered 200, and the status of the others is on their profiles.
The readings of a vendor's own domain are three reads dated 5 November 2026: this site's plain fetch (a home page request, a request for Accept: text/markdown, /llms.txt and a made-up path), Ora's cached score read through its public API without starting a scan, and Cloudflare's keyless scan at isitagentready.com. 70 vendors have a Cloudflare scan and 61 an Ora score; where a score is missing the profile says why. They describe the vendor's website, not its product. Vendors are listed alphabetically within each type.

The six standards
Each profile gives every standard one of four statuses. Supports means the vendor's own pages say it does this. Partial means they say it with a condition, a limit or for some products only. Announced means they say it is coming. No statement means the pages read say nothing. The evidence and the page it rests on sit beside each status.
- llms-txt
- llms.txt: the vendor generates or serves /llms.txt.
- markdown-negotiation
- Markdown on Accept: the vendor answers Accept: text/markdown on the same URL.
- markdown-twin
- Markdown twin: the vendor publishes a .md copy of each page.
- initial-html
- Initial HTML: the vendor puts the page content in the server HTML by default.
- real-404
- Real 404: the vendor answers a missing path with a 404 status.
- vary-accept
- Vary: Accept: the vendor sends Vary: Accept when it negotiates.

Contentful has no profile: www.contentful.com answered HTTP 429 to the pricing and newsroom requests on 2026-11-05 and was not retried, so no page of its own was read. These names were not reached in this edition and come first in the next: Storyblok, Payload, Sitecore, Contentstack, Builder.io, Optimizely, Hygraph, Craft CMS, Joomla, Umbraco, Plone, MediaWiki, Sitefinity, Contensis, Terminalfour, CoreMedia, Odoo, SilverStripe, Concrete CMS, Grav, WordPress.com, GoDaddy Airo, Square Online, v0, Bolt.new, Replit, Jimdo, Carrd, Tilda, Render, bunny.net, Deno Deploy, NitroPack, Botify, Pelican, Quarto, Doxygen, Waku, Qwik, SolidStart, llms-txt-php. WPML, SEOmatic and the WordPress performance plugins named in crawl generator tags do not decide what an agent reads first and were never candidates.
