The short version

  • Each has a real cost: Pusher the free Sandbox plan is capped at 100 concurrent connections, which is quickly outgrown by production apps.; RabbitMQ not built for replay: once consumed, a message is gone, which is exactly what Kafka exists to change
  • They diverge on capability: Pusher covers Pub/sub channels, RabbitMQ covers Flexible routing.
  • Prices and features above were last checked on 29 August 2026.

Where each one falls short

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

Pusher

  • The free Sandbox plan is capped at 100 concurrent connections, which is quickly outgrown by production apps.
  • Pricing jumps sharply between tiers (e.g. $49 to $99 to $299), leaving few options for teams with moderate but growing usage.
  • Priority support with faster response times costs an additional $3,000/month on top of plan pricing.

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

Pusher: What does Pusher cost?

Pusher Channels offers a free Sandbox plan (200k messages/day, 100 connections) and paid plans starting at $49/month for Startup, scaling up through Pro, Business, and several higher tiers up to $1,199/month, plus custom Enterprise pricing.

Source
RabbitMQ: Is RabbitMQ free?

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

Pusher: Can I change or cancel my plan?

Yes, customers can log into the dashboard and adjust their plan at any time, including upgrading, downgrading, or cancelling.

Source
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.

Pusher: How is usage metered?

Usage is measured by concurrent connections and messages per day; a message counts both the publish and each delivery, so publishing one message to 50 subscribers counts as 51 messages.

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.
