The short version

  • Each has a real cost: n8n starter tier limited to 1 project and 5 concurrent executions; RabbitMQ not built for replay: once consumed, a message is gone, which is exactly what Kafka exists to change
  • They diverge on capability: n8n covers Workflow automation, RabbitMQ covers Flexible routing.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

n8n

  • Building AI agents and workflow automation for technical teamsnot RabbitMQ
  • Visual workflow design with capability to write custom JavaScript or Python codenot RabbitMQ
  • Enterprise deployments with self-hosted or cloud optionsnot RabbitMQ
  • Integrating 500+ pre-built applications with custom API connectionsnot RabbitMQ

RabbitMQ

  • Distributing background jobs to a pool of workers with retriesnot n8n
  • Decoupling services that need delivery rather than a replayable historynot n8n
  • Routing messages by pattern to different consumers from one publishernot n8n

Where each one falls short

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

n8n

  • Starter tier limited to 1 project and 5 concurrent executions
  • Starter and Pro tiers restricted to Cloud hosting only, not self-hosted
  • Business tier requires 6 months minimum commitment at €667/month
  • SSO/SAML/LDAP authentication requires Business or Enterprise tier
  • Dedicated support with SLA available only on Enterprise plan

RabbitMQ

  • Not built for replay: once consumed, a message is gone, which is exactly what Kafka exists to change
  • Throughput ceilings are lower than a log-based platform under very heavy streaming loads
  • Queues that build up degrade broker performance, so consumer lag is an operational problem rather than just a backlog
  • Clustering and partition behaviour has historically been a source of hard-to-diagnose problems

Answered from the vendors’ own pages

n8n: Is there a free version of n8n?

Yes, n8n Community Edition is free and open-source, available for self-hosting on GitHub with unlimited users and workflows.

Source
RabbitMQ: Is RabbitMQ free?

Yes, open source with no licence fee. Broadcom sells commercial support.

n8n: What is the difference between n8n plans?

Plans differ by monthly workflow executions (2,500 for Starter, 10,000 for Pro, 40,000 for Business), concurrent execution limits, AI credits, and shared project counts.

RabbitMQ: RabbitMQ or Kafka?

RabbitMQ is a message broker: simpler to run and better at flexible routing and work queues. Kafka is a replayable event log built for very high throughput streaming, and much heavier to operate.

n8n: Does n8n offer annual billing discounts?

Yes, n8n offers 17% off when billing annually instead of monthly, and provides a Startup Plan at 50% off Business pricing for companies under 20 employees.

Source
RabbitMQ: Can RabbitMQ replay messages?

Not in the way Kafka can. Messages are removed once acknowledged, so rebuilding state from history is not the model.
