The short version

Only NATS has a free tier, so it costs nothing to try first.
Each has a real cost: NATS core NATS has no persistence at all, so messages are lost if no subscriber is listening; Skaleet the installed base is in the tens rather than the hundreds, so the pool of consultants and systems integrators who know the platform is small and expensive.
They diverge on capability: NATS covers Very low latency, Skaleet covers Cloud-native core.

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

Skaleet

The installed base is in the tens rather than the hundreds, so the pool of consultants and systems integrators who know the platform is small and expensive.
Speed references are mostly greenfield launches inside large groups, which is an easier problem than migrating an existing book off a legacy core.
It is European-centric, with payment rails and regulatory work concentrated on SEPA and EU requirements rather than global coverage.
As a smaller vendor carrying a bank core, it attracts hard concentration and viability questions in procurement that larger competitors do not face.
Pricing is unpublished and scaled by accounts and transactions, so a bank whose volumes grow faster than forecast faces cost escalation it did not model.

Answered from the vendors’ own pages

NATS: Is NATS free?

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

Skaleet: What was Skaleet called before?

TagPay. The company rebranded to Skaleet while keeping the same platform lineage.

NATS: Does NATS persist messages?

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

Skaleet: Can I buy just the payment hub?

Yes. The payment engine is licensable standalone and can sit over an existing core, which is a common first step.

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.

Skaleet: How fast are real deployments?

Named European deployments have gone live in six to twelve months, including a Crédit Agricole savings platform live in Germany in eight months.
