How do they charge?

Different approach here. Aiven uses usage-based pricing, while Convex 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. Convex: Convex is cheap at the entry point to hook indie devs and small teams, but that $2,500/mo floor for Business & Enterprise puts them in premium territory once you're a real company — there's almost nothing in between. They're winning developers early and betting that switching costs keep them once usage scales into serious money.
