The short version

  • Only Solace PubSub+ has a free tier, so it costs nothing to try first.
  • Each has a real cost: Solace PubSub+ no pricing is published at any tier, so evaluation requires a sales engagement before you can even judge whether it is in budget, and broker tier sizing determines cost in ways buyers frequently get wrong.; TIBCO Enterprise Message Service the 2026 roadmap is oriented to modernising existing estates rather than winning new deployments, so a greenfield buyer is choosing a product its vendor is not investing in for growth.
  • They diverge on capability: Solace PubSub+ covers Multi-protocol broker, TIBCO Enterprise Message Service covers JMS 2.0 broker.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

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

Where each one falls short

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

Solace PubSub+

  • No pricing is published at any tier, so evaluation requires a sales engagement before you can even judge whether it is in budget, and broker tier sizing determines cost in ways buyers frequently get wrong.
  • The free Standard edition has hard capacity and support limits, which makes it useful for development but means any real deployment triggers a commercial negotiation.
  • The proprietary SMF protocol gives the best performance and feature coverage, so teams that lean on it acquire real switching costs even though open protocols are supported.
  • Operating a self-managed high availability broker pair with disaster recovery is a specialist task, and Solace expertise is scarce in the hiring market compared with Kafka skills.
  • Event Portal and Mission Control are licensed as part of platform packages, so the governance tooling that makes an event mesh manageable is not simply included with the broker.

TIBCO Enterprise Message Service

  • The 2026 roadmap is oriented to modernising existing estates rather than winning new deployments, so a greenfield buyer is choosing a product its vendor is not investing in for growth.
  • Nothing is published on price, licensing is per server or per core, and renewal pricing across the Cloud Software Group portfolio has risen sharply since the 2022 Citrix and TIBCO combination.
  • It is a JMS broker, not a durable event log, so replay, stream reprocessing and long retention patterns require Kafka alongside it rather than instead of it.
  • Skills are concentrated in a contractor market that is ageing, and hiring engineers who want to work on EMS is materially harder than hiring for Kafka.
  • Deep integration with the rest of the TIBCO stack, particularly BusinessWorks, makes partial migration difficult; teams commonly find that leaving EMS means replacing several products at once.

Answered from the vendors’ own pages

Solace PubSub+: Is there a free version of Solace?

Yes, the Standard edition of the software event broker is free for production within capacity limits, with no vendor support.

TIBCO Enterprise Message Service: Is TIBCO EMS still supported?

Yes, releases continue under Cloud Software Group, with 10.x versions shipping and FIPS 140-3 compliance added.

Solace PubSub+: Does Solace publish prices?

No. Cloud, software and appliance are all quoted, based on broker tier from ENT-250 to ENT-100K and licensing model.

TIBCO Enterprise Message Service: What does it cost?

Nothing is published. It is licensed per server or per core with annual maintenance, usually inside a wider TIBCO agreement.

Solace PubSub+: Why buy an appliance in 2026?

Deterministic low latency with message processing offloaded to hardware, which matters in capital markets and little elsewhere.

TIBCO Enterprise Message Service: Should a new project choose EMS?

Rarely. The vendor roadmap targets existing estates, and greenfield event-driven projects generally start with Kafka or a cloud broker.

Solace PubSub+: Can it replace Kafka?

Not for log retention and stream reprocessing. It is stronger at multi-protocol routing and guaranteed delivery, and the two are often bridged.

TIBCO Enterprise Message Service: Can EMS talk to Kafka?

Yes, an EMS transport for Apache Kafka is supported on Linux, which is the usual bridge during modernisation.
