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.

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.

What it does not do

DeveloperHub sends an agent that is not recognised as a bot or assistant a JavaScript shell with no article text, so content in the initial HTML depends on user-agent detection.
