The short version

  • Only RudderStack has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; RudderStack on the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline
  • They diverge on capability: IBM MQ covers Assured once-only delivery, RudderStack covers Data collection.
  • 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.

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.

RudderStack

  • On the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline
  • The free plan allows 250,000 events a month
  • Growth starts at $265 a month for 1 million events, with volume sold in tiers up to 25 million
  • Overage is charged as the gap to the next tier's price rather than per event, so a small excess costs a full tier step

Answered from the vendors’ own pages

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.

RudderStack: What is RudderStack's free plan limit?

RudderStack's free plan includes 250K events per month with 16 SDK sources, 200+ cloud destinations, warehouse destinations, and Reverse ETL at no cost.

Source
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.

RudderStack: How much does RudderStack Growth plan cost?

RudderStack Growth plan costs $265 per month with annual billing discount available, providing 1 million events per month (up to 25 million available), unlimited team members, and 2 workspaces.

Source
IBM MQ: What does MQ Advanced add?

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

RudderStack: What happens if I exceed my RudderStack event limit?

On the free plan, data processing stops after your second consecutive overage. Paid plan customers face overage fees calculated as the difference between the next tier's pricing and their current plan.

Source
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.
