A subdomain creates instant organizational satisfaction. It also creates another SEO, deploy, analytics, navigation, auth, copy and maintenance surface.

Before opening one for a new tool, I ask three things: does the tool create independent value, does it have its own user job and return loop, and does separate release or data ownership actually help it?

If not, it stays inside the existing system.
