I like the simplicity. Also, I'm assuming it's not free, it would be nice to know what's the price before signing up. Maybe you could just add some sort of a disclaimer, e.g. Generate / Create new site (free up to 1k visitors/month, $5 after). Good luck!
Oh! If you don't mind my asking, how do you go about selling custom domains? Or if there are resources you can point me to, that would be helpful, too.
Not sure @andreyazimov is actually selling domains, only allowing you to connect your own, right? But if you want to actually sell domains via your application I'm sure that's possible via Namecheap API or something similar.
