Every price is the monthly cost, at list prices on monthly billing, of running the same app database in a US region: a 10 GB production app (the headline), a 250 MB side project and a 100 GB growing app, each with a fixed number of reads, writes and developers, on the cheapest self-serve plan that fully covers it. Free plans count when they cover the whole job and allow production use; trials and sign-up credits do not.
