Redocly: vendor profile

In short

Redocly writes llms.txt and clean .md copies by default, and one setting, llmstxt.hide, removes both. Sitemaps, canonical links and JSON-LD wait for the owner: no siteUrl in redocly.yaml means no sitemap, and no jsonLd object means no structured data. Annual billing puts Pro at $249 a month.

Redocly Docs platform

Redocly is a docs-as-code platform for API docs whose sites ship llms.txt, clean .md copies, markdown on Accept: text/markdown, an MCP server and WebMCP tools, with sitemaps, canonical links and JSON-LD driven by redocly.yaml.

What it does for this layer

  • Redocly says Redoc began at Rebilly, a Texas payments company that wrote its own documentation tool after Swagger UI let it down, and that Redocly later launched as a paid SaaS. [vendor claim] source, read 5 November 2026.
  • Redocly writes /sitemap.xml and adds rel=canonical links only once siteUrl is set in redocly.yaml, and on versioned projects only the default version is marked canonical. [primary source] source, read 5 November 2026.
  • Redocly emits JSON-LD only when the owner writes a jsonLd object in redocly.yaml or page front matter and picks the Schema.org type. [primary source] source, read 5 November 2026.
  • Redocly validates links and redirects while content is added, and its built-in CI/CD jobs stop a project with link errors from publishing. [primary source] source, read 5 November 2026.
  • Redocly's llmstxt.hide option switches off both llms.txt and the clean Markdown copies of the pages it lists, and it defaults to false. [primary source] source, read 5 November 2026.
  • Redocly's llmstxt.excludeFiles setting takes file paths or glob patterns such as docs/**/*.md, including negated globs, to keep pages out of llms.txt. [primary source] source, read 5 November 2026.
  • Redocly marks WebMCP experimental and publishes tools such as search_docs, read_page and navigate_page automatically; browser support is an origin trial in Chrome 149 and Edge 150. [primary source] source, read 5 November 2026.
  • Redocly's Visibility tag targets a block at humans or at agents and decides what reaches the Markdown version of a page. [primary source] source, read 5 November 2026.
  • Redocly's Realm changelog lists faster server-side rendering for OpenAPI reference pages with heavily reused schemas, confirming reference pages render on the server. [primary source] source, read 5 November 2026.
  • Redocly Pro costs $249 a month billed annually, $2,988 a year, with unlimited seats, readers and Git contributors and an MCP server for the docs. [primary source, 2026-11-05] source, read 5 November 2026.
  • Redocly charges $390 a year for each project beyond the 3 in Pro or the 10 in Scale, the $729-a-month plan billed annually. [primary source, 2026-11-05] source, read 5 November 2026.
  • On 2026-11-05 Redocly returned markdown for redocly.com/docs/platform/ai-ready when asked with Accept: text/markdown, yet the only Vary value it sent was Cookie. [observed, 2026-11-05] source, read 5 November 2026.
  • Appending .md to redocly.com/docs/platform/content/realm-seo on 2026-11-05 returned HTTP 200 text/markdown of 5,184 bytes. [observed, 2026-11-05] source, read 5 November 2026.
  • A made-up path under redocly.com/docs returned HTTP 404 text/html on 2026-11-05 even when the request asked for text/markdown. [observed, 2026-11-05] source, read 5 November 2026.
  • Redocly's own SEO docs page carried no application/ld+json block in its initial HTML on 2026-11-05, in line with JSON-LD being opt-in. [observed, 2026-11-05] source, read 5 November 2026.

markdown-negotiationno statementNeither the AI-ready page nor the seo config reference mentions Accept-based negotiation, though redocly.com returned text/markdown to such a request on 2026-11-05.source
markdown-twinsupportsllmstxt options govern the clean Markdown versions of pages listed in llms.txt.source
initial-htmlsupportsThe Realm changelog refers to server-side rendering of OpenAPI reference pages.source

What it does not do

  • Redocly serves markdown on Accept: text/markdown but did not list Accept in Vary on 2026-11-05, so shared caches are not told the body depends on that header.
