Source: https://agentreadyhtml.com/vendors/developerhub/ Site: Agent Ready HTML Last reviewed: 2026-11-05 # DeveloperHub: vendor profile In short DeveloperHub sends crawlers it does not recognise a 20,124-byte HTML shell with no article text. Recognised bots and assistants get rendered pages, and with llms.txt switched on a markdown copy of the page. There is no llms-full.txt. Plus costs $99 a month billed annually. ## At a glance **standards.txt** developerhub ```text llms-txt = supports markdown-negotiation = partial markdown-twin = supports initial-html = partial real-404 = no statement vary-accept = no statement ``` 2 supports, 2 partial or announced, 2 no statement. **DeveloperHub** Docs platform Hosted docs and API reference platform that renders pages in the browser for people, serves cached bot-rendered HTML to crawlers, and when llms.txt is on gives AI assistants markdown at the page URL, .md copies, a per-version llms.txt and WebMCP tools.
