A lot of this seems manageable to me - like I could imagine myself being able to build it - but I have no idea how the author handled the domain names part and hosting all these websites. How did you just "throw together" a registrar and a hosting service? Seems like they built heroku and namecheap as side facets to their "tiny project." I must be missing something.

Startup Founders often say, “do things that don’t scale”. If I were trying this, I might just register the domains in my account, list myself as the admin, and list them for everything else. No building necessary until you prove the idea.

Exactly. For a $99/year subscription it makes sense to manually perform a one-time setup. That being said, domain name registration APIs are a thing [1]. Hosting should be even more trivial with a multi-tenant architecture.
