  • Only Solace PubSub+ has a free tier, so it costs nothing to try first.
  • Each has a real cost: Celigo prices are not published on any of the three editions; 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: Celigo covers App integration, Solace PubSub+ covers Multi-protocol broker.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Celigo

  • Prices are not published on any of the three editions
  • Billed on endpoints and flows, so the cost is driven by how many systems you connect rather than by volume through them
  • API Builder, lookup caching and a sandbox all require the Professional edition
  • Single sign-on is optional on Standard and included from Professional up
  • Unlimited endpoints and the full governance features are Enterprise only

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.
