About:
MQTT Explorer is a comprehensive, open-source GUI client for MQTT brokers, designed to provide a clear overview of your MQTT topics in real-time. It excels at visualizing topic hierarchies and message payloads, making it easier to debug and interact with IoT devices. Its auto-discovery and topic tree features significantly simplify the management of complex MQTT networks.

Key Features:

Real-time topic tree visualization and auto-discovery
Payload editor with JSON and raw data support
Message history and diff view for easy debugging
Clean, modern, and intuitive user interface
Cross-platform support (Windows, macOS, Linux)

Use Cases:

Debugging and monitoring IoT device communication
Developing and testing MQTT-based applications
Exploring and understanding complex MQTT topic structures

Alternatives:

MQTT.fx – MQTT.fx is a popular alternative but has a more dated UI and lacks the advanced topic tree visualization of MQTT Explorer.
mosquitto_pub/sub – Command-line tools that are powerful for scripting but lack a graphical interface for interactive exploration and debugging.
