The short version

  • Only Activiti has a free tier, so it costs nothing to try first.
  • Each has a real cost: Activiti the last stable release was 8.2.0 in January 2024, and while release candidate builds continue, a two-year gap between stable versions is a real risk signal for a production dependency.; 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: Activiti covers BPMN 2.0 engine, 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.

Activiti

  • An Alfresco or Hyland content services deployment where Activiti is already the embedded workflow enginenot IBM MQ
  • A Java application that needs to embed a BPMN engine as a library under a permissive licencenot IBM MQ
  • An organisation that has ruled out Camunda 8 on licence grounds and needs an Apache 2.0 alternativenot IBM MQ
  • Document-centric approval workflows where the process engine sits inside the content management stack rather than beside itnot IBM MQ

IBM MQ

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

Where each one falls short

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

Activiti

  • The last stable release was 8.2.0 in January 2024, and while release candidate builds continue, a two-year gap between stable versions is a real risk signal for a production dependency.
  • Both Camunda and Flowable forked away and took large parts of the contributor base with them, so the community, tutorials and third-party tooling around Activiti are much thinner than around either fork.
  • Commercial support is only realistically available by buying Hyland Alfresco subscriptions, so there is no way to pay for Activiti support on its own.
  • Activiti Cloud imposes a distributed architecture of several Spring Boot services plus Keycloak, which is heavy for teams who simply wanted an embeddable engine.
  • Documentation is dated and partly split between old Alfresco sites and Hyland Connect, and the transition between Activiti 6, 7 and 8 architectures makes much of the older material actively misleading.

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 Activiti or IBM MQ better?
Neither clearly leads. Activiti starts at Free and IBM MQ at $312/month, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Activiti or IBM MQ?
Activiti has a free tier; the other does not. Paid plans start at Free for Activiti and $312/month for IBM MQ.
Does Activiti or IBM MQ run on more platforms?
Both run on Linux, Windows, Docker, Kubernetes, so platform support will not decide this one for you.
Can I use Activiti for free?
Yes. Activiti has a free tier, so you can try it without paying. IBM MQ starts at $312/month.
What is Activiti best used for?
Activiti is most often used for an alfresco or hyland content services deployment where activiti is already the embedded workflow engine, a java application that needs to embed a bpmn engine as a library under a permissive licence, an organisation that has ruled out camunda 8 on licence grounds and needs an apache 2.0 alternative, document-centric approval workflows where the process engine sits inside the content management stack rather than beside it. Of those, an alfresco or hyland content services deployment where activiti is already the embedded workflow engine and a java application that needs to embed a bpmn engine as a library under a permissive licence are not what IBM MQ is typically brought in for.
What can Activiti do that IBM MQ cannot?
Activiti covers BPMN 2.0 engine, Activiti Cloud, Modeler, Java and REST APIs. IBM MQ covers Assured once-only delivery, Multi-platform queue managers, Native high availability, Advanced Message Security.

Answered from the vendors’ own pages

Activiti: Is Activiti still maintained?

Yes, Hyland continues to publish builds, but the last stable release was 8.2.0 in January 2024.

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.

Activiti: What is its relationship to Camunda and Flowable?

Both are forks of Activiti: Camunda in 2013 and Flowable in 2016, when core developers left Alfresco.

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.

Activiti: What licence is it?

Apache 2.0, which distinguishes it from Camunda 8’s source-available licence.

IBM MQ: What does MQ Advanced add?

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

Activiti: Should I choose Activiti for a new project?

Only if the Apache licence or an existing Alfresco deployment is decisive. Flowable and Camunda have far larger ecosystems.

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.
