The short version

  • Only Solace PubSub+ has a free tier, so it costs nothing to try first.
  • Each has a real cost: HighByte Intelligence Hub it is subscription only with no perpetual licence, so the data pipelines are a permanent operating cost and stop working if the subscription lapses.; 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.
  • They diverge on capability: HighByte Intelligence Hub covers Data modelling, Solace PubSub+ covers Multi-protocol broker.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

HighByte Intelligence Hub

  • It is subscription only with no perpetual licence, so the data pipelines are a permanent operating cost and stop working if the subscription lapses.
  • Pricing is per site with a 18,500 USD floor, so a small plant or a proof of concept pays enterprise money for a handful of tags; there is no tag-scaled or starter tier.
  • The Hub does not store data. It has no historian, so a destination outage longer than the store-and-forward buffer means lost data and you still need a historian or warehouse underneath.
  • Definitions of a site and a plant are negotiated rather than published, which creates room for disagreement at renewal when a customer adds a building or a second line.
  • The product depends on a small vendor with a narrow focus; if your integration needs drift towards general ETL or streaming, you end up running HighByte alongside a separate data stack rather than instead of one.

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.

Answered from the vendors’ own pages

HighByte Intelligence Hub: What does a HighByte licence actually cost?

18,500 USD per year for Professional covering one plant, 50,000 USD for three factories, 65,000 USD for a cloud data centre aggregation point.

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.

HighByte Intelligence Hub: Is pricing based on tag count?

No. All licences include unlimited data models and pipelines; the licence covers a coverage area, not a data volume.

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.

HighByte Intelligence Hub: Does HighByte store historical data?

No. It models and routes data in motion. You still need a historian or a warehouse as the destination.

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.

HighByte Intelligence Hub: Can I buy it perpetually?

No. It is an annual subscription only.

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.
