Features & Capabilities

This is an MQTT client and test tool. MQTT is a machine-to-machine (M2M) messaging protocol commonly used for IoT applications. For more information on MQTT visit http://mqtt.org

MQTTool can connect to authenticated and unauthenticated MQTT brokers, subscribe to topics, and publish messages to topics.

I built this tool as i was doing my own MQTT investigations and I've posted it hoping others would find it useful too. I continue to use it on projects, and I'm continuing to look to improve this tool. If there are changes that would make this more useful, please send me feedback. Thanks!

I was able to connect to my local ESP32 server, subscribe to topics and publish on topics. The interface is very intuitive. I would suggest one improvement - option to publish in JSON format. I published a message in JSON format but it was not recognized by the server. It would be great to add JSON format. I commend you for this very nice app !!! Thanks :)
