The short version

  • Only NATS has a free tier, so it costs nothing to try first.
  • Each has a real cost: Fivetran HVR pricing not published separately; part of Fivetran's usage model; NATS core NATS has no persistence at all, so messages are lost if no subscriber is listening
  • They diverge on capability: Fivetran HVR covers Log-based change capture, NATS covers Very low latency.

NATS

Where each one falls short

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

Fivetran HVR

  • Pricing not published separately; part of Fivetran's usage model
  • Requires Fivetran relationship for implementation
  • Limited standalone documentation and community resources
  • May be overkill for simple batch replication needs
  • Competitive offerings provide more transparent per-connector pricing

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

Answered from the vendors’ own pages

Fivetran HVR: What databases does Fivetran HVR support?

HVR supports major databases including Oracle, SQL Server, PostgreSQL, MySQL, and others that emit transaction logs.

NATS: Is NATS free?

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

Fivetran HVR: Is HVR part of standard Fivetran pricing?

Yes, HVR is integrated into Fivetran's usage-based pricing model with standard per-row-synced and transformation costs.

Source
NATS: Does NATS persist messages?

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

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.
