How do they charge?

Different approach here. Aiven uses usage-based pricing, while Supabase goes with hybrid. That changes the math depending on your team size and usage.

Which one is a better deal?

Depends on what you need. Aiven: Aiven sits mid-to-premium compared to raw cloud-native options like RDS or Cloud SQL, trading lower absolute cost for a fully managed, multi-cloud abstraction layer. They're chasing teams who want Postgres (or Kafka, ClickHouse, etc.) without being locked into one hyperscaler, not teams purely hunting rock-bottom price. Supabase: Supabase undercuts Firebase and traditional managed Postgres on entry price, using the free tier and cheap Pro plan to hook indie devs and startups away from rolling their own infra. The jump to $599 for Team is steep though, positioning it less as 'affordable at scale' and more as a wedge to land small teams cheap then monetize hard once they're locked into Postgres, Auth, and Storage.
