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

Notepad++

  • Windows-only, with no official native macOS or Linux build.
  • Lacks built-in debugging or project/build management found in full IDEs.
  • Plugin quality and maintenance varies since they are community-contributed.
  • No built-in version control integration beyond what plugins provide.
