Docus: vendor profile

In short

Docus negotiates Accept: text/markdown with Vary: Accept, User-Agent and sends agents a Markdown 404, but outside Vercel prerendered pages stay HTML and agents fall back to the .md twin. docus.dev returned 2,209 bytes of markdown for a docs page on 2026-11-05. The theme is free under the MIT licence; v5.15.0 shipped on 2026-10-14.

What it does for this layer

Docus is a Nuxt documentation theme built with Nuxt UI and Nuxt Content, and new projects start from npx create-docus my-docs. [primary source] source, read 5 November 2026.
Docus includes the nuxt-llms module by default, which generates and pre-renders /llms.txt and /llms-full.txt from every documentation page. [primary source] source, read 5 November 2026.
Docus switches a page to Markdown when the URL ends in .md, when the Accept header prefers text/markdown over text/html, or when the User-Agent is a known AI crawler such as ClaudeBot or GPTBot. [primary source] source, read 5 November 2026.
Every Docus response that can be HTML or Markdown carries Vary: Accept, User-Agent so a CDN never hands the wrong variant to a browser or an agent. [primary source] source, read 5 November 2026.
Docus negotiation runs in a Nitro middleware and, on Vercel, at the edge; on other hosts a prerendered page stays HTML and agents reach its Markdown through the .md URL. [primary source] source, read 5 November 2026.
Docus serves source Markdown at /raw/<content-path>.md with text/markdown and a Link header back to the HTML page, and rewrites llms.txt links to those raw files. [primary source] source, read 5 November 2026.
Docus emits JSON-LD through nuxt-schema-org, with WebSite and WebPage on every page and TechArticle and BreadcrumbList on documentation pages. [primary source] source, read 5 November 2026.
Docus generates /sitemap.xml with @nuxtjs/sitemap and turns it into a sitemap index with one sitemap per locale on multilingual sites. [primary source] source, read 5 November 2026.
Each Docus site exposes an MCP server at the /mcp path of its documentation URL. [primary source] source, read 5 November 2026.
Docus v5.15.0, released on GitHub on 2026-10-14, lazy-loads components and tree-shakes schema.org composables out of the client bundle. [primary source, 2026-10-14] source, read 5 November 2026.
docus.dev answered Accept: text/markdown on /en/getting-started/installation with 2,209 bytes of text/markdown and Vary: Accept, User-Agent on 2026-11-05. [observed] source, read 5 November 2026.
With curl's default Accept, a made-up docus.dev path returned status 404 with a 1,236-byte Markdown body on 2026-11-05; the same kind of path requested with Accept: text/html returned a 404 HTML page. [observed] source, read 5 November 2026.

Standard	Status	What the vendor's pages say	Source
llms-txt	supports	Docus integrates nuxt-llms by default and generates and pre-renders /llms.txt and /llms-full.txt.	source
markdown-negotiation	partial	Docus negotiates on the page URL through a Nitro middleware, but outside Vercel prerendered pages stay HTML and agents need the .md URL.	source
