About RabbitMQ

RabbitMQ is an open-source message broker that originally implemented the AMQP protocol and has since been extended with plugin support for protocols such as MQTT and STOMP.

RabbitMQ is designed to be flexible and scalable with various types of exchanges, routing options and queue types. You can control how messages are distributed, filtered and handled using features like acknowledgments, custom plugins and consumer groups. Its modular plugin architecture allows you to add MQTT, STOMP support or custom federation and shovel solutions without touching the core.

Despite its technically advanced foundations, RabbitMQ is easy to get started with: you can run it locally via Docker, use a web UI for monitoring, and cover basic use cases with a few Python or Node scripts. At the same time, it powers large organizations-from message handling in web applications to real-time workflows in IoT systems.
