Agent Ready HTML

Theneo: vendor profile

In short

Theneo builds llms.txt from each page's SEO fields and adds a .md copy per section. A request for Accept: text/markdown got the ordinary HTML page back on 2026-11-05. Unknown paths on docs.theneo.io answered 200 with the welcome page and a canonical tag pointing at themselves. Business costs $120 a month per workspace.

Theneo Docs platform

API docs and developer portal platform that builds llms.txt from each page's SEO fields, adds llms-full.txt and a .md copy per section, and server-renders titles, meta tags and canonical links; a made-up path on its own docs site returned 200 instead of 404.

What it does for this layer

  • Theneo builds llms.txt from each published page's SEO Title, Description and Slug fields, and each entry links to the page's .md source; drafts and unpublished pages are left out. [primary source] source, read 5 November 2026.
  • Theneo rebuilds llms.txt on every publish, and a page with no SEO description still appears with a blank description. [primary source] source, read 5 November 2026.
  • Theneo serves every published section as markdown at its URL plus .md, holding both the API request and its prose, with no export step. [primary source] source, read 5 November 2026.
  • Theneo's August 2026 release notes added llms-full.txt next to llms.txt, holding the whole documentation in one file. [primary source] source, read 5 November 2026.
  • Theneo's release of 2026-01-15 began serving an auto-generated robots.txt at the sitemap's base path; free users get the default rules and paying subscribers can edit them. [primary source, 2026-01-15] source, read 5 November 2026.
  • The same Theneo release moved page titles and meta tags into the server-rendered initial HTML so crawlers that skip JavaScript read them. [primary source, 2026-01-15] source, read 5 November 2026.
  • Since 2026-01-15 Theneo adds canonical tags to every public page and drops content-less header sections from sitemap.xml and llms.txt. [primary source, 2026-01-15] source, read 5 November 2026.
  • Theneo projects can stay public while carrying a no-index flag, and per-section SEO titles, descriptions, keywords and Open Graph fields are edited in SEO Management. [primary source] source, read 5 November 2026.
  • Theneo generates a runnable MCP server from an OpenAPI spec at editor.theneo.io/mcp, with stdio, HTTP or SSE transport and a checkbox list of operations to expose as tools. [primary source] source, read 5 November 2026.
  • Theneo's pricing page JSON-LD lists a free Starter plan (1 public project), Business at $120 per month per workspace billed annually ($150 monthly) and Growth at $400 billed annually ($450 monthly). [primary source, 2026-11-05] source, read 5 November 2026.
  • Theneo says more than 18,000 companies use it. [vendor claim] source, read 5 November 2026.
  • On 2026-11-05 a made-up path on docs.theneo.io returned HTTP 200 with the What Is Theneo welcome page and a canonical tag pointing at the made-up URL, a soft 404. [observed, 2026-11-05] source, read 5 November 2026.
  • On 2026-11-05 docs.theneo.io answered Accept: text/markdown with the normal HTML page, while the same page's .md URL returned 4,221 bytes of text/plain markdown and /llms-full.txt returned 1,100,994 bytes. [observed, 2026-11-05] source, read 5 November 2026.
