EMQ (Erlang MQTT Broker) is a distributed, massively scalable, highly extensible MQTT message broker written in Erlang/OTP.

EMQ is fully open source and licensed under the Apache Version 2.0. EMQ implements both MQTT V3.1 and V3.1.1 protocol specifications, and supports MQTT-SN, CoAP, WebSocket, STOMP and SockJS at the same time.

EMQ provides a scalable, reliable, enterprise-grade MQTT message Hub for IoT, M2M, Smart Hardware and Mobile Messaging Applications.
