If your docs live on Mintlify or GitBook, your Site can show them at a path such as yourdomain.com/docs. Visitors stay on your domain, and search engines count your docs as part of your Site instead of a separate one. You don’t need to change any DNS or set up a proxy. Docs on your domain is part of the paid plans.
1

Set up the path in your docs tool

Your docs tool has to know it’s being served at a path. In Mintlify, open Settings → Custom domain, turn on Host at, and enter your domain with the path /docs. In GitBook, open your docs site’s Domain and redirects, choose Set up a subdirectory, enter yourdomain.com/docs, then copy the proxy URL it shows.
2

Connect it in your Site

Open your Site’s Settings → Docs. Pick Mintlify or GitBook, then enter your Mintlify subdomain (like acme) or paste GitBook’s proxy URL. Keep the path as /docs unless you chose another one in step 1.

Check, then turn it on

Press Check. It asks your docs tool for your docs at that path and tells you whether it’s set up. Then turn the switch on and save. It works straight away, without publishing your Site again.

Good to know

  • Your Site must be published. Docs show on its custom domain and its BoostGPT subdomain.
  • The path belongs to your docs once it’s on. If your Site has its own pages under that path, Settings tells you, and your docs replace them there.
  • When your Site uses the robots.txt BoostGPT makes for it, that file also lists your docs sitemap.
  • Search, the docs assistant and page changes work as they do on your docs tool. Cookies set by your Site stay with your Site, and nothing from your docs tool can set cookies on your domain.
  • Moving docs from a subdomain like docs.yourdomain.com? Add a redirect from it to yourdomain.com/docs at your DNS provider, so old links and search rankings carry over.
