Suitable tools are an important part of setting up and testing an MQTT installation.
Tools are available for Windows,Linux,Android and IPhone
In this tutorial I will give you an overview of popular tools that are available for download on the Internet, and also some of my own tools that I have created that may also be of use
Client Simulation Tools
There are a variety of tools available for use on a PC and also smart phone/tablet.
- Command Line tools
- Browser Tools
- Smart Phone and Tablet Tools
Command Line Tools
Mosquitto_sub – Simple subscribe utility for testing. This comes with the Mosquitto broker.
Mosquitto_pub – Simple publish utility for testing. This comes with the Mosquitto broker.
Browser Tools – Chrome
MQTT-Lens – Chrome add-on for publishing and subscribing to an MQTT broker. –Using MQTT-Lens- Beginners Guide
MQTT-Box– Chrome add-on for publishing and subscribing. More feature rich than MQTT-Lens. Supports Websockets.
Android Tools-Smart Phone and Tablet
MQTT Dashboard – Simple tool to publishing and subscribing.
MQTT Dash- Create MQTT dashboards for the smart home
Broker Testing Tools
My Python Script Test Tools
These scripts are scripts that I’ve written while experimenting with MQTT.
This test tool is a simple python script that tests if a broker is up and how long messages take, just like the traditional IP ping utility.
MQTT Ping Usage
The utility is designed to be run from the command line.
The script requires only a single parameter which is the broker IP or domain name.Type python mqtt-ping.py -h
- 1.use -c 10 for 10 pings
- 2. Use -d 5 for 5 second delay between pings
- use -s to only print end result
Retained Messages Utility–
Two scripts one for displaying and optionally deleting retained messages on a topic tree. The other is used for creating topics with retained messages for testing purposes.

MQTT- Monitor -Monitors Selected topics
This is very useful tool for monitoring topics on a broker. I use it frequently when testing.
By default it only display changed messages.
Type python mqtt-monitor.py -h
- Can add multiple topics by repeated use of -t option
- Use -v no to display only changed messages
- Use -c 100 to stop after 100 seconds
- Use -q value (0 or 1 or 2) to set the QOS of all topics
- Use -d yes to turn on debugging mode
The script is designed to be run from the command line.
