Editorial take
Why it stands out
RabbitMQ is still most compelling when the team's real problem is work distribution and routing, not when it is trying to re-create an event-streaming platform by habit.

Tool profile
Open-source message broker for queues, routing, and reliable asynchronous workloads, with commercial support and enterprise features sold separately.
Background job queues and asynchronous processing
RabbitMQ remains one of the most practically useful messaging tools because it solves the classic brokered-messaging problem very well. It is strong when teams need queues, exchanges, routing patterns, reliable background work distribution, and general asynchronous system decoupling without immediately stepping into full event-streaming architecture. That is why it still appears in real production stacks even as newer messaging systems gain attention.
The economic story is straightforward at the project level. RabbitMQ is open source and free to use, while commercial support and extra enterprise features come through Tanzu RabbitMQ rather than a public simple pricing table on rabbitmq.com. The official support pages make clear that commercial support exists with longer support timelines and added features, but list pricing is sales-led. That means RabbitMQ is best framed as free OSS messaging infrastructure with optional commercial support rather than as a normal public-SaaS queue product.

Apache Kafka
Free planEvent streaming and event-driven architectures
Open-source distributed event streaming platform for high-throughput pipelines, pub/sub, and stream-processing ecosystems.
Choose Kafka when replayable event streams and ecosystem breadth matter more than the lightest possible operational footprint.
Pricing snapshot
RabbitMQ is open-source software and free to use. The official project site points commercial buyers to Tanzu RabbitMQ for support and enterprise features, but public list pricing is not posted on rabbitmq.com. In practice, the cost is self-managed infrastructure plus any separate commercial support agreement.
Arcjet
Free planApplication runtime security
Runtime security toolkit for modern applications and AI systems that helps teams enforce quotas, block bots, prevent prompt abuse, and ship app-level protections in code.
Closer to application-runtime security and abuse-prevention tooling than to classic perimeter appliances.
