Where each one falls short

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

Paragon

  • No published pricing rates or specific plan costs
  • Pricing is entirely custom based on Connected Users
  • Both Pro and Enterprise plans require direct contact for pricing

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

Paragon: How much does Paragon cost?

Paragon does not publish pricing rates. The company uses a custom pricing model based on Connected Users (the number of tenant organizations using integrations), requiring customers to request custom quotes.

Source
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.

Paragon: What are Paragon's pricing plans?

Paragon offers Pro and Enterprise plans. The Pro plan includes unlimited integrations, access to all three products, and custom integrations. The Enterprise plan adds self-hosted options, priority support with SLAs, and SAML SSO.

Source
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.

Paragon: Does Paragon offer a free trial?

Yes, a free trial is available via signup, though specific trial duration and limitations are not detailed on the pricing page.

Source
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.

Paragon: How does Paragon determine the cost of my plan?

Pricing is customized based on business model and the number of Connected Users, meaning organizations must contact Paragon's sales team for a custom quote.

Source
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.
