Django Registration equivelent for frappe

This is what I was eluding to in my previous post. Something as to where when a customer signs up a profile and a custom app is givin to them. Along with the usual email verification tool. Where in frappe is this.

I do not need the subdomain registration. Is there an option that allows just the app creation. In the erpnext you much do a custom.erpnext.com I want to do it as audio.com/custom.

What is the best way to do this or is it hard coded into frappe
