RabbitMQ is an open-source and commercially supported messaging broker written in Erlang which allows applications to scale by decoupling the sending and receiving of data. RabbitMQ features flexible messaging routing via exchanges and queues, server clustering, mirrored queues for high availability, and clients for a variety of languages. The home page is http://www.rabbitmq.com.

RabbitMQ is open source message broker software that implements the Advanced Message Queuing Protocol (AMQP), the open standard for business messaging. Written in Erlang, the RabbitMQ server is based on a proven platform and offers a reliable, highly available, scalable and portable messaging system with predictable and consistent throughput and latency.

RabbitMQ is 100% open source and 100% based on open standard protocols freeing users from dependency on proprietary vendor-supplied libraries. It is designed from the ground up to interoperate with other message systems. It is a leading implementation of AMQP.

Through adapters, it supports MQTT and STOMP, both natively and over HTTP/WebSockets. SMTP is also available thanks to a community plugin. Support for the software is offered through both a thriving community of active contributors and a range of commercial support services available through Pivotal (https://pivotal.io/oss).
