The receipts and the bills above: one app for one month, 10 GB of data, 50,000 users, 30,000 emails, 100,000 map loads, 250 GB of egress and 2,000,000 function calls, with one person on the team; each plan's row lists its own workload. Prices: each vendor's paid list price on October 27, 2026. Assumes each vendor's paid plan that holds the workload, with its published overage rates past the plan's allowance. Excluded: taxes, and any usage the workload does not list. Firebase and Google Maps: Firestore storage, reads and writes are left out, so this is the least the stack costs. Substrio's allowances count map tiles, while Mapbox and Google Maps bill map loads: a map load and a map tile are not the same unit.
