About:
Mqttui is a lightweight, terminal-based user interface for MQTT clients. It allows users to interactively subscribe to topics, view incoming messages in real-time, and publish messages directly from the command line. The tool is designed for quick debugging and monitoring of MQTT brokers without the need for heavy GUI applications.
Key Features:
  • Interactive terminal UI for browsing topics and messages
  • Support for both subscribing and publishing to MQTT topics
  • Lightweight and fast, written in Rust
  • Keyboard-driven interface for efficient navigation
Use Cases:
  • Debugging IoT device communication in real-time
  • Monitoring MQTT broker traffic from the terminal
  • Quickly publishing test messages to trigger device actions
Alternatives:
  • mosquitto_pub/mosquitto_sub – Standard CLI tools that are script-friendly but lack an interactive UI.
  • MQTT Explorer – A comprehensive GUI tool that offers a visual overview but requires a desktop environment.
