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

TIBCO Mashery

  • Lack of support for open API standards requires workarounds
  • Policy management is difficult and sometimes requires support intervention for configuration changes
  • Monetization and customization features are inadequate for some enterprise use cases
  • Delays under heavy load conditions; stability issues reported affecting performance
  • Logging and monitoring limitations; logs are hard to follow when calls cannot be filtered by keys
