The short version

  • Each has a real cost: Knack plans are capped by stored records, so an application that logs events or keeps history rather than current state climbs tiers on data volume alone, and archiving old records becomes a permanent maintenance chore rather than a one-off.; 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: Knack covers Visual database builder, TIBCO Enterprise Message Service covers JMS 2.0 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.

Knack

  • Plans are capped by stored records, so an application that logs events or keeps history rather than current state climbs tiers on data volume alone, and archiving old records becomes a permanent maintenance chore rather than a one-off.
  • API access is capped per day, at 1,000 calls on the entry plan and 10,000 at the Corporate tier, so a scheduled sync or a busy automation can exhaust the day's quota before the working day ends and integrations then fail silently.
  • The application itself cannot be exported or self-hosted; records can be downloaded but the pages, roles, flows and business logic exist only inside Knack, so outgrowing the platform means rebuilding the app rather than moving it.
  • Customisation beyond the builder is limited to injected CSS and JavaScript that Knack's support does not cover, so any non-standard interface behaviour becomes yours to maintain against a DOM the vendor can change without warning.
  • Compliance capabilities that regulated buyers assume are baseline, HIPAA and GovCloud options, advanced SSO, IP restrictions and private environments, are gated to the Corporate and Enterprise tiers, so a small regulated pilot cannot legitimately start on an entry plan.

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

Knack: Is Knack charged per user?

No. User accounts are unlimited on all plans. Plans are bounded by stored record count, file storage, API calls per day and automation transactions.

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.

Knack: What happens when I exceed the record limit?

You move to a higher tier or reduce stored records. Because the limit is on data rather than people, apps that accumulate history hit it while apps that track a fixed set of entities generally do not.

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.

Knack: Can I export my application or self-host it?

You can export record data. The application itself, its pages, roles, permissions and flows, is not exportable and cannot be self-hosted, so leaving means rebuilding 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.

Knack: Is it suitable for public-facing portals?

That is its strongest case, because logins are unlimited and role-based permissions are built in. The constraint is record volume and API throughput, not audience size.

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.

Knack: Can I use it for regulated data?

HIPAA-aligned and government cloud options exist but only on the Enterprise tier, along with private server environments. Lower tiers should not be used for regulated workloads.
