In reality, this was a good toy project to test out Cloudflare's platform. I've traditionally used AWS / Netlify / and a few others. Cloudflare was pretty easy to set up and they offer at-cost .ai domains. $140 for 2 years... painful for Nanna, but hey, boosts that valuation multiple by at least 2x.
I'll probably use this as a project to experiment with some other things, like some of the new payments / billing startups being built for AI-specific use cases.
