+- MQTTX is a newly released product that uses Electron cross-platform technology, with beautiful interface and low resource occupation. MQTTX changes the common single client mode in interaction, allowing to save multiple connection information;
 - It is easy to use, can quickly create connections, and provides a more comprehensive MQTT parameter configuration, so that users can respond to simulation test of any use scenario and pattern, including support for MQTT v5.0;
 - It can send and receive messages in the form of message chat. The interaction process is simple and easy to understand. It allows multiple clients to connect at the same time and freely switch to communicate with each other. It has better interaction and greatly improves the efficiency of interactive debugging;
 - It is fully open-source and supports multiple platforms.
