Public MQTT Broker

Our public HiveMQ MQTT broker is open for anyone to use. Feel free to write an MQTT client that connects with this broker. We have a dashboard so you can see the amount of traffic on this broker. We also keep a list of MQTT client libraries that can be used to connect to HiveMQ.

You can access the broker at:
Broker: broker.hivemq.com
TCP Port: 1883
Websocket Port: 8000
