# MQTTape

> Open-source MQTT 3.1.1 and MQTT 5.0 traffic recorder, packet inspector, topic explorer, payload viewer, and replay tool for desktop and browser.

MQTTape is an MQTT client, not a broker. The desktop app supports TCP, TLS, WebSocket, custom CA certificates, and mTLS on Windows, macOS, and Linux. Web Lite runs in a browser and connects through WebSocket. The interface supports Traditional Chinese and English.
