I shipped a pay-to-rank experiment on Cloudflare’s free tier (under $2)

I built isopod.lol this week as a distribution test: 8 plates on a cartoon isopod, steal = last price + $10, PayPal for the charge.

The part other builders kept asking about was not the bow. It was how you stop two people buying the same plate, and how far you can get without a VPS.

Stack: Workers, D1, Turnstile, Access, Email Routing for the owner magic link. PayPal is the only paid vendor. Domain + whatever tiny PayPal fees you actually take. I wrote the checkout / version / webhook path here:

If you’re cloning an outbid-style board or shipping a real product on the same house, that page is the notes I wish I had on day one. Happy to answer stack questions in the thread.
