Scale

Pay as you go, higher rates

Teams needing an SLA and bigger databases.

Which plan to pickStart on Free. Move to Professional when you launch, mainly for daily backups and the bigger limits. Business is a big jump aimed at teams of 50 or more, so most readers will never need it.Spark is enough until real users arrive. Move to Blaze when you need Cloud Functions or you're close to a quota, and set a budget alert the moment you do. There's no middle tier, so your bill goes straight from nothing to usage based.Free covers more than you'd expect, including several small live apps. Move to Launch when a project needs more than 100 compute hours a month or a longer restore window. Scale is for teams that need an SLA, not for individuals.
