Hello team, I was wondering if Frontend and Backend site can be hosted on two different URL's. Means CMS site on one URL and Admin (/Umbraco) on different domain. Without using Umbraco Heartcore.

Is it in a headless scenario? Of using the Umbraco templates?

No we are using standard practice where site can be hosted on "domain.com" and admin can login through "domain.com/Umbraco".
