| 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. | Stay on Hobby and pay only for the services you run. A $7 web service and a $6 database cover most small apps. Move to Pro when a team needs to share the workspace or you want autoscaling and previews. |
