MQTT Bhai: MQTT Client & IoT

MQTT Bhai is a fast, secure MQTT client and IoT dashboard for Android. Test any MQTT broker (Mosquitto, HiveMQ, EMQX, AWS IoT), publish and subscribe to topics, and monitor ESP32, Arduino and Raspberry Pi devices live — whether you're a firmware engineer, a maker, or a Home Assistant user.

Built by the team at IoT Bhai, MQTT Bhai delivers a desktop-class debugging experience right from your phone: clean, reliable, and built for real IoT work.
