The short version

  • Each has a real cost: Apache Kafka operationally heavy to self-host: brokers, storage, rebalancing and upgrades are a standing job, which is why managed Kafka is a large market; n8n starter tier limited to 1 project and 5 concurrent executions
  • They diverge on capability: Apache Kafka covers Durable commit log, n8n covers Workflow automation.

Where each one falls short

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

Apache Kafka

  • Operationally heavy to self-host: brokers, storage, rebalancing and upgrades are a standing job, which is why managed Kafka is a large market
  • Overkill for straightforward job queues, where a simpler broker is easier to run and reason about
  • Ordering guarantees hold per partition, not per topic, and getting partitioning wrong is a common and expensive design mistake
  • The ecosystem is fragmented across the Apache project and vendor distributions, so documentation and tooling advice often assume a particular distribution

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

Answered from the vendors’ own pages

Apache Kafka: Is Apache Kafka free?

Yes. Kafka is open source under the Apache License v2 with no licence fee. Costs come from the infrastructure you run it on, or from a managed service such as Confluent Cloud.

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
Apache Kafka: How is Kafka different from a message queue?

A queue usually removes a message once it is consumed. Kafka keeps an ordered, durable log, so consumers track their own position and history can be replayed — which is what makes rebuilding state after a bug possible.

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.

Source
Apache Kafka: Who uses Kafka?

The project reports use by more than 80% of the Fortune 100, with over 5 million lifetime downloads.

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
Apache Kafka: Do I need to run Kafka myself?

No. Self-hosting is the operationally expensive option; managed services such as Confluent Cloud run the brokers for you and bill on throughput and storage instead.
