| Attribute | Firebase | Neon | Convex |
|---|---|---|---|
| Plans | SparkOur pick Free Early projects and apps with a small audience. | FreeOur pick Free Side projects and learning. | Free and Starter Free, then pay as you go Side projects and small teams getting started. |
Blaze Pay as you go, no monthly fee Anything that might grow past the free quotas. | Launch Pay as you go, no monthly minimum Small production apps. | ProfessionalOur pick $25/developer/mo Products with real users. | |
Scale Pay as you go, higher rates Teams needing an SLA and bigger databases. | Business and Enterprise From $2,500/mo Larger companies with compliance and scale needs. | ||
| Which plan to pick | 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. | 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. |
