  • Each has a real cost: Marqo pricing not publicly available, enterprise sales-only model; NATS core NATS has no persistence at all, so messages are lost if no subscriber is listening
  • They diverge on capability: Marqo covers Semantic search, NATS covers Very low latency.

Where each one falls short

Marqo

  • Pricing not publicly available, enterprise sales-only model
  • Requires custom implementation and integration work
  • Limited to ecommerce use cases compared to general search
  • Model training requires sufficient customer behavior data

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
