Welcome to the Erlang MQTT Broker's wiki!

emqx(Erlang MQTT Broker) is a massively scalable and clusterable MQTT V3.1/V3.1.1 broker written in Erlang/OTP.

emqx is fully open source and licensed under the Apache Version 2.0. emqx implements both MQTT V3.1、V3.1.1 and V5.0 protocol specifications, and supports WebSocket, STOMP, SockJS, CoAP and MQTT-SN at the same time.

--

The emqx project provides a scalable, enterprise grade, extensible open-source MQTT broker for IoT, M2M, Smart Hardware, Mobile Messaging and HTML5 Web Messaging Applications.

Sensors, Mobiles, Web Browsers and Application Servers could be connected by emqx brokers with asynchronous PUBSUB MQTT messages.
