MQTTX is a cross-platform MQTT 5.0 client tool open sourced by EMQ, which can run on macOS, Linux and Windows, and supports formatting MQTT payload.

MQTTX simplifies test operation with the help of a familiar, chat-like interface. It’s easy and quick to create multiple, simultaneous online MQTT client connections, and can test the connection, publishing, and subscription functions of MQTT/TCP, MQTT/TLS, MQTT/WebSocket as well as other MQTT protocol features.

MQTT stands for MQ Telemetry Transport. It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks.

Currently available for download from these app stores

The macOS users can install MQTTX using brew cask

brew install --cask mqttx

1. Get MQTT Broker Ready.

   • If you do not need to deploy the MQTT Broker locally, you can use the public MQTT 5.0 Broker provided by EMQX Cloud for testing:

     Broker IP: broker.emqx.io
     Broker TCP Port: 1883
     Broker SSL Port: 8883

   • To run MQTT Broker locally, EMQX is recommended: An Open-Source, Cloud-Native, Distributed MQTT Broker for IoT.

2. Connection configuration. Click the + button in the left menu bar and fill in the corresponding required fields in the form.

3. After the connection information is configured, click the Connect button in the upper right corner to create a connection and connect to MQTT Broker.

4. After the MQTT is connected successfully, you can perform MQTT publish and subscription tests.

MQTTX is designed to connect to test MQTT Brokers such as EMQX, The one-click connection and simple graphical interface make it easy to connect to EMQX or EMQX Cloud to debug and explore functional features.
