The short version

Only RabbitMQ has a free tier, so it costs nothing to try first.
Each has a real cost: Marqo pricing not publicly available, enterprise sales-only model; RabbitMQ not built for replay: once consumed, a message is gone, which is exactly what Kafka exists to change
They diverge on capability: Marqo covers Semantic search, RabbitMQ covers Flexible routing.

Where each one falls short

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

Marqo

Pricing not publicly available, enterprise sales-only model
Requires custom implementation and integration work
Limited to ecommerce use cases compared to general search
Model training requires sufficient customer behavior data

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

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.

Marqo: Which ecommerce platforms does Marqo integrate with?

Marqo has native integrations with Shopify, Adobe Commerce (Magento), and Salesforce Commerce Cloud, and also provides API access for custom implementations.

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.

Marqo: How is Marqo priced?

Marqo pricing is customized based on catalog size, search volume, and feature requirements. Contact their sales team to book a demo and discuss pricing.
