The short version

  • Each has a real cost: NATS core NATS has no persistence at all, so messages are lost if no subscriber is listening; Zipkin less active development and smaller community momentum than Jaeger
  • They diverge on capability: NATS covers Very low latency, Zipkin covers Trace collection and search.
  • Prices and features above were last checked on 29 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

NATS

  • Edge and IoT messaging where a lightweight broker mattersnot Zipkin
  • Replacing a heavier broker when the workload does not need its guaranteesnot Zipkin

Zipkin

  • Adding distributed tracing quickly without standing up heavy infrastructurenot NATS
  • Java and Spring Boot estates, where instrumentation support is long-establishednot NATS
  • Small deployments where Jaeger is more than the problem requiresnot NATS

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

Zipkin

  • Less active development and smaller community momentum than Jaeger
  • Fewer features: sampling, storage options and UI are all more limited
  • The interface is dated and slower to work with on large trace volumes
  • Tracing alone still leaves metrics and logs in separate tools during an incident

Questions people ask

Is NATS or Zipkin better?
Neither clearly leads. NATS starts at Free and Zipkin at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, NATS or Zipkin?
NATS starts at Free and Zipkin at Free.
Does NATS or Zipkin run on more platforms?
NATS runs on Linux, macOS, Windows, Docker, Kubernetes. Zipkin runs on Linux, Docker, Kubernetes, Self-hosted.
Can I use NATS for free?
Both have a free tier, so you can try either at no cost before committing.
What is NATS best used for?
NATS is most often used for service-to-service messaging where latency is the binding constraint, edge and iot messaging where a lightweight broker matters, replacing a heavier broker when the workload does not need its guarantees. Of those, service-to-service messaging where latency is the binding constraint and edge and iot messaging where a lightweight broker matters are not what Zipkin is typically brought in for.
What can NATS do that Zipkin cannot?
NATS covers Very low latency, JetStream, Single binary, Request-reply. Zipkin covers Trace collection and search, Dependency diagram, Simple deployment, Pluggable storage.

Answered from the vendors’ own pages

NATS: Is NATS free?

Yes, open source and CNCF-graduated. Synadia sells a managed service.

Zipkin: Is Zipkin free?

Yes, open source with no licence fee.

NATS: Does NATS persist messages?

Core NATS does not — it is fire-and-forget. JetStream adds persistence, streaming and replay when you need them.

Zipkin: Zipkin or Jaeger?

Jaeger has more momentum, more features and CNCF backing. Zipkin is lighter and quicker to stand up, and remains well supported in the Java and Spring ecosystem.

NATS: NATS or Kafka?

NATS is far lighter and lower latency, and much simpler to run. Kafka is the answer when you need a durable replayable log and a large connector ecosystem.

Zipkin: Does Zipkin work with OpenTelemetry?

Yes. OpenTelemetry can export to Zipkin, which is now the usual way to instrument for it.
