Read 2026-11-05. Source: https://agentreadyhtml.com/vendors/mintlify/ Site: Agent Ready HTML Last reviewed: 2026-11-05 # Mintlify: vendor profile In short Mintlify sends markdown by Accept header, by user agent for assistants such as Claude-User, and at .md URLs. A plain fetch loses text from custom React components, which render in the browser only. The mintlify.site address stays crawlable after a custom domain goes live. Starter is free without the assistant; Pro is $450 a month on annual billing. ## At a glance **standards.txt** mintlify ```text llms-txt = supports markdown-negotiation = supports markdown-twin = supports initial-html = partial real-404 = supports vary-accept = no statement ``` 4 supports, 1 partial or announced, 1 no statement. **Mintlify** Docs platform Mintlify is a hosted docs platform that server-renders pages, hands markdown to agents by Accept header, user agent or .md URL, and generates llms.txt, skill.md and schema.org JSON-LD for public docs sites.
