Cardpost

Cardpost is a postcard app that refuses to be fast. A card travels at the speed of the real distance between two cities: Singapore to Lisbon takes 11 days, and nothing can rush it. The recipient sees nothing until the day it lands, then breaks a wax seal to read it. Public cards pass between strangers instead, collecting signatures and distance as they circle the world. Built with Next.js and Supabase. The delay isn't a bug in Cardpost. It's the entire product.
