Robust multi-protocol messaging broker for cloud-native applications
RabbitMQ delivers reliable, high-throughput messaging across AMQP, MQTT, STOMP, and streaming protocols, with extensive tooling, Kubernetes support, and commercial options for enterprise deployments.
RabbitMQ is a mature, feature‑rich messaging broker that enables reliable, high‑throughput communication between applications. It natively supports a wide range of protocols—including AMQP 0‑9‑1, AMQP 1.0, MQTT 3.1/3.1.1/5.0, STOMP 1.0‑1.2, and their WebSocket variants—allowing diverse clients to interoperate through a single platform. Advanced queue types such as quorum queues provide data safety and consistency, while the RabbitMQ Stream protocol offers persistent, append‑only logs with non‑destructive consumer semantics for event‑streaming workloads.
The broker can be deployed on‑premises, in virtual machines, or orchestrated with Kubernetes using the official RabbitMQ Cluster Operator, which automates node provisioning, clustering, and upgrades. Comprehensive tooling includes CLI utilities, extensive documentation, and built‑in metrics exposed to Prometheus for Grafana dashboards. Enterprises can opt for commercial editions and Broadcom‑backed support, while the community offers forums, Discord, and Libera Chat for assistance. RabbitMQ’s MPL 2.0 license ensures freedom to modify and redistribute the software.
When teams consider RabbitMQ, these hosted platforms usually appear on the same shortlist.

Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Microservices communication
Decoupled services exchange messages reliably via AMQP or MQTT, scaling horizontally.
IoT telemetry ingestion
Collect sensor data over MQTT/WebSocket and route to processing pipelines.
Event streaming and replay
Persist event logs with RabbitMQ Streams for replayable analytics.
High-availability workloads
Use quorum queues to ensure data safety across node failures.
