MQTT Web Interface (MQTTUI) is a user-friendly web-based interface designed to facilitate the monitoring, visualization, and interaction with MQTT (Message Queuing Telemetry Transport) brokers. This tool allows users to easily publish and subscribe to topics, view real-time data streams, and manage MQTT interactions from a convenient web interface. It is particularly beneficial for developers and IoT enthusiasts working on projects that involve numerous devices communicating through MQTT, as it simplifies the process of observing message traffic and system performance.

MQTTUI is lightweight and can be self-hosted, making it a flexible solution for personal or team-based development environments. Users can customize the interface to their liking and benefit from features such as connection management, topic filtering, and message history, which collectively enhance the debugging and monitoring experience. With MQTTUI, users gain insightful control over their MQTT infrastructure directly through their web browsers, streamlining their workflows and enhancing productivity in IoT development.
