What is RabbitMQ?

RabbitMQ is an open source message broker that helps applications communicate by sending and receiving messages through queues. It is released under the Mozilla Public License 2.0 and supports open protocols including AMQP 0-9-1, AMQP 1.0, and MQTT 5.0, with client libraries available for many programming languages. Typical uses include decoupling microservices, distributing background jobs among workers, and streaming events between systems.

The broker can be self-hosted on premises or run in the cloud, and it can be extended with plugins for federation, message shovels, and protocol bridges like STOMP and MQTT over WebSockets. Organizations that want commercial support can choose VMware Tanzu RabbitMQ from Broadcom, an enterprise edition that adds 24/7 support, disaster recovery replication, and additional security features on top of the open source core.
