About MQTTX
MQTTX is an MQTT client for developing and testing MQTT applications. It connects to a broker, publishes messages and subscribes to topics. It supports MQTT 5.0, 3.1.1 and 3.1.
It comes in three forms: a desktop app for macOS, Windows and Linux, a command-line tool, and a web version that can also run in Docker. Extra features include scripts, benchmarks, IoT data simulation and an AI assistant called MQTTX Copilot. It is made by the team behind the EMQX broker.
