About:
EMQX is a scalable, open-source MQTT broker designed for high-performance IoT messaging. It enables reliable data exchange between massive numbers of connected devices and backend services. The platform supports MQTT 5.0, MQTT 3.1.1, and other protocols, ensuring robust connectivity for real-time applications.
Key Features:
  • Massive scalability supporting millions of concurrent connections
  • High-performance messaging with sub-millisecond latency
  • Distributed clustering for high availability and fault tolerance
  • Extensible plugin architecture and rule engine for data processing
Use Cases:
  • IoT device telemetry and remote monitoring systems
  • Real-time messaging for connected vehicles and smart infrastructure
  • Industrial IoT (IIoT) data collection and control systems
Alternatives:
  • mosquitto – Lightweight broker suitable for smaller deployments, but lacks EMQX's distributed clustering and extreme scalability
  • vernemq – Distributed MQTT broker focused on scalability, though EMQX is often noted for its rich rule engine and ecosystem integration
