Thank you!

The original site was on Railway and written in Pug! It crashed after Riley's tweet first went viral, then Riley did the heroic work of caching it all with Cloudflare after waking up to the site being down. After millions of unique visitors we racked up about $10 in costs.

This time we switched to Next.js 16 + Vercel, used Cloudflare R2 for asset hosting, and used Neon as the db. R2 has free egress, and Vercel + Next is cheap if cached correctly.

A special someone at Vercel gave us some tips on caching this one earlier today. We started by just using unstable_cache all over the place, and now we're migrating to ISR + full static pre-generation of as many pages as we can via generateStaticParams.
