Not crass, I like sharing! We're all here to learn from each other.
The monetization model is just referral links to Namecheap, where I get a 10% commission. I want to make that a bit more elegant (especially for people with uBlock Origin, which it doesn't track), and also add a few other referrals (logo makers and maybe hosting).
Couldn't think of other ways to monetize this without making it obnoxious (I hate ads, and making it pay-to-use also seems restrictive to me). If you have any ideas, I'd be open to hear them!
you could try being your own nameserver...through namesilo or something...it's like pretty cheap there already per domain, I think if you used their api as a reseller, and upcharged like 15% on each domain's price you could make more than the namecheap commission...
