EMQ X broker is a fully open source, highly scalable, highly available distributed MQTT messaging broker for IoT, M2M and Mobile applications that can handle tens of millions of concurrent clients.
Starting from 3.0 release, EMQ X broker fully supports MQTT V5.0 protocol specifications and backward compatible with MQTT V3.1 and V3.1.1, as well as other communication protocols such as MQTT-SN, CoAP, LwM2M, WebSocket and STOMP. The 3.0 release of the EMQ X broker can scaled to 10+ million concurrent MQTT connections on one cluster.
The EMQ X broker is cross-platform, which supports Linux, Unix, macOS and Windows. It means EMQ X can be deployed on x86_64 architecture servers and ARM devices like Raspberry Pi.
