| Which plan to pick | Start 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. | Build and test on Starter. Move to Builder when you need more room or a second project, and to Standard only when the app has real users and needs backups and SSO. |
