The short version

  • Each has a real cost: Camunda camunda 7 Community Edition stopped receiving security patches after the 7.24 release in October 2025, so free production deployments are now running unpatched software.; IBM MQ virtual Processor Core licensing is capacity-based, so an over-provisioned server is charged for cores the queue manager never uses, and consumption ratios differ between MQ and MQ Advanced.
  • They diverge on capability: Camunda covers BPMN 2.0 execution, IBM MQ covers Assured once-only delivery.
  • 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.

Camunda

  • Long-running business processes crossing several services where the state must be visible to non-developersnot IBM MQ
  • Insurance claims or loan origination where the process model is itself a compliance artefactnot IBM MQ
  • Replacing orchestration logic scattered across microservices with one engine that owns the state machinenot IBM MQ
  • A regulated organisation that needs an auditable record of how each process instance actually executednot IBM MQ

IBM MQ

  • Core banking or payments where a message must participate in the same transaction as a database updatenot Camunda
  • A mainframe estate that needs reliable messaging between z/OS applications and distributed Linux servicesnot Camunda
  • Regulated file movement that must be auditable end to end, using Managed File Transfernot Camunda
  • Replacing bespoke retry and idempotency code in inter-system integrations with a queue that guarantees once-only deliverynot Camunda

Where each one falls short

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

Camunda

  • Camunda 7 Community Edition stopped receiving security patches after the 7.24 release in October 2025, so free production deployments are now running unpatched software.
  • Camunda 8 Self-Managed is source-available under the Camunda License 1.0, not open source: production use requires a paid licence, and organisations that adopted Camunda for its Apache licence have to renegotiate that decision.
  • Migrating from Camunda 7 to 8 is a rewrite rather than an upgrade because the engine, the API and the persistence model all changed, and there is no in-place migration for running instances.
  • Camunda 8 Self-Managed has substantial infrastructure requirements including Zeebe brokers, Elasticsearch and Identity, which is a considerable operations burden compared with the single database that Camunda 7 needed.
  • Pricing is not published at all, so evaluating total cost requires a sales process, and there is no way to size a budget before committing engineering time to a proof of concept.

IBM MQ

  • Virtual Processor Core licensing is capacity-based, so an over-provisioned server is charged for cores the queue manager never uses, and consumption ratios differ between MQ and MQ Advanced.
  • Container licensing requires Kubernetes with the IBM License Service, so Podman or plain Docker deployments cannot use the optimised metric and pay materially more.
  • Distributed and z/OS platforms use different licensing models, and organisations running both routinely misapply one to the other, which surfaces as exposure at audit.
  • Operating MQ needs specialist skills that are increasingly scarce, and the pool of engineers who understand channel and queue manager administration is shrinking with every retirement.
  • IBM’s acquisition of Confluent in March 2026 puts MQ and Kafka under one vendor, which resolves the integration story but removes the competitive tension that kept renewal negotiations honest.

Questions people ask

Is Camunda or IBM MQ better?
Neither clearly leads. Camunda starts at On request and IBM MQ at $312/month, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Camunda or IBM MQ?
Camunda starts at On request and IBM MQ at $312/month.
Does Camunda or IBM MQ run on more platforms?
Camunda runs on Web, Linux, Docker, Kubernetes. IBM MQ runs on Linux, Windows, Docker, Kubernetes.
What is Camunda best used for?
Camunda is most often used for long-running business processes crossing several services where the state must be visible to non-developers, insurance claims or loan origination where the process model is itself a compliance artefact, replacing orchestration logic scattered across microservices with one engine that owns the state machine, a regulated organisation that needs an auditable record of how each process instance actually executed. Of those, long-running business processes crossing several services where the state must be visible to non-developers and insurance claims or loan origination where the process model is itself a compliance artefact are not what IBM MQ is typically brought in for.
What can Camunda do that IBM MQ cannot?
Camunda covers BPMN 2.0 execution, DMN decision tables, Zeebe engine, Operate console. IBM MQ covers Assured once-only delivery, Multi-platform queue managers, Native high availability, Advanced Message Security.

Answered from the vendors’ own pages

Camunda: Is Camunda still open source?

No. Camunda 8 Self-Managed ships under the Camunda License 1.0, which is source-available and requires a paid production licence.

IBM MQ: How is IBM MQ licensed?

By Virtual Processor Core subscription, around 312 US dollars per VPC per month for MQ and 583 for MQ Advanced, minimum one year.

Camunda: What happened to Camunda 7?

Its final feature release, 7.24, was in October 2025 and the Community Edition receives no further patches. Enterprise support runs to April 2030.

IBM MQ: Should we replace MQ with Kafka?

Only if you actually need a replayable log. MQ is a transactional queue; replacing it with Kafka usually means rebuilding transactional semantics in application code.

Camunda: Can I upgrade from 7 to 8?

Not in place. The engine, API and persistence changed, so it is a rewrite of the integration layer.

IBM MQ: What does MQ Advanced add?

Advanced Message Security, Managed File Transfer, MQTT telemetry and quorum-based high availability.

Camunda: What does it cost?

Camunda does not publish prices. Both self-managed production and SaaS require a quote.

IBM MQ: Does container deployment change the cost?

Yes. Optimised container licensing needs Kubernetes with the IBM License Service; Podman or Docker deployments do not qualify.
