Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

NATS

  • Core NATS has no persistence at all, so messages are lost if no subscriber is listening
  • JetStream adds the durability but also the operational complexity NATS is chosen to avoid
  • A much smaller ecosystem than Kafka or RabbitMQ, with fewer connectors and integrations
  • Fewer people know it, so hiring and existing organisational knowledge favour the alternatives

Turso

  • Pro tier costs $416.58 monthly, a significant jump from Scaler plan
  • Overage charges apply on all tiers beyond storage and row limits
  • Enterprise options require contacting sales for custom pricing
