| Attribute | Convex | Neon | PlanetScale |
|---|---|---|---|
| Plans | Free and Starter Free, then pay as you go Side projects and small teams getting started. | FreeOur pick Free Side projects and learning. | Postgres, single node From $5/mo Staging and small apps that can tolerate a restart. |
ProfessionalOur pick $25/developer/mo Products with real users. | Launch Pay as you go, no monthly minimum Small production apps. | Postgres, high availabilityOur pick From $15/mo Production apps with paying users. | |
Business and Enterprise From $2,500/mo Larger companies with compliance and scale needs. | Scale Pay as you go, higher rates Teams needing an SLA and bigger databases. | Metal From $50/mo Apps where database speed is the bottleneck. | |
Vitess (MySQL) From $39/mo MySQL apps that need to shard as they grow. | |||
Enterprise Custom Single-tenant or fully managed setups. | |||
| 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. | 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. | Don't start here for a weekend project; Neon or Supabase are free. When a product has paying customers, the $15 high-availability Postgres is the sensible entry point. Only go to Metal once Insights shows the disk is the slow part. |
