During learning and using MQTT, a handy client tool can greatly facilitate the user to explore the MQTT features and debug the functional components. Developers from all over the world have developed a number of client-side testing tools for the MQTT protocol around different operating systems.
These client tools come in a wide variety of ways, with different functional focus and uneven quality levels. Therefore, for beginners and even MQTT experts, how to choose a suitable MQTT client tool is a problem.
This article will collect as much as possible, and make a comprehensive evaluation of various MQTT client tools on the market for readers' reference.
MQTT client tools are often used to establish connections with MQTT Brokers for the operations of topic subscriptions and messaging. The features of an MQTT client tool can be evaluated from the following aspects:
This article will combine the features of each client tool to conduct evaluations from the above aspects. The client tools for the election are as follows:

Mosquito CLI has multiple configuration options, supports TLS certificate connections via a proxy server, supports debug mode, and provides more detailed message information in debug mode.
Mosquito CLI is lightweight, compact, and easy to install, allowing multiple MQTT clients to be built in parallel with multiple connections to complete message publish/subscribe testing.
It is also very easy to use, only needs to provide a few parameters in the default use environment:
## Enable debug mode to subscribe to testtopic/# topic wivwiv-mac:workspace emqtt$ mosquitto_sub -t "testtopic/#" -d Client mosqsub/66418-wivwiv-ma sending CONNECT Client mosqsub/66418-wivwiv-ma received CONNACK Client mosqsub/66418-wivwiv-ma sending SUBSCRIBE (Mid: 1, Topic: testtopic/#, QoS: 0) Client mosqsub/66418-wivwiv-ma received SUBACK Subscribed (mid: 1): 0 Client mosqsub/66418-wivwiv-ma received PUBLISH (d0, q0, r0, m0, 'testtopic/1', ... (5 bytes)) Hello ## Publish a message to testtopic / 1 topic mosquitto_pub -t "testtopic/1" -m "Hello"
For more information about the installation and use of Mosquitto and Mosquitto CLI, refer to Mosquitto website.
MQTT X is a cross-platform visual MQTT client tool developed by EMQ, which is open-sourced under Apache license 2.0 protocol.
Project address: Github MQTTX
Download link: Github MQTTX Release
MQTTX has the following features:
MQTTX is the latest product, which adopts the Electron cross-platform technology with a beautiful interface and low resource footprint. MQTTX changes the common single client mode in interaction, organizes client information according to the broker configuration, allows multiple client information to be saved in the same broker configuration, and sends and receives messages in the interactive form of message chat. It allows to establish multiple client connections at the same time and switch to communicate with each other by themselves, which has better interaction, and greatly improves the efficiency of interactive debugging.
As of now, MQTTX has released the v1.1.1 version, and more follow-up features are still waiting to be developed.
MQTT.fx is a currently mainstream MQTT client developed by Jens Deters that can quickly verify whether it can interact with IoT Hub services to publish or subscribe to messages. MQTT.fx is applicable for the Apache License 2.0 protocol without providing source code.
Project address: source code not provided
Download link: MQTT.FX
MQTT fx has the following features:
$SYS(support HiveMQ and Mosquitto)
MQTT.fx is an established MQTT client tool. All the cloud product provider related product documentation tutorials such as Azure IoT Hub, AWS IoT, and Alibaba Cloud IoT use MQTT.fx as an example. MQTT.fx is developed by JavaFX technology, and may have a stuck experience on some older machines because of Java virtual machine relationship.
In terms of basic functions, MQTT .fx can save multiple connection configurations, support multiple types of TCL encryption, and specify multiple types of certificates. When creating a connection, you can specify to use an HTTP proxy server. After the connection is successful, the entire publishing and subscription functions are relatively reasonable and smooth. It is a function highlight that the
topics Collector function can find the topic of subscription through other means such as the Broker-side proxy. Mqtt.fx also supports the connection test of Google cloud IOT.
If you are using HiveMQ or Mosquitto Broker, MQTT.fx provides a dedicated tab to visualize Broker status by subscribing to both system topics (topics for publishing Broker run information) , and get information about the system version and time of the broker, the number of clients, the number of messages, network traffic, and load status.
In general, MQTT.fx has rich and mature functions, and supports all the configuration items that may be encountered in the TCP connection. Except for the poor interaction, users can only establish one connection at the same time, which cannot satisfy the simultaneous use demand of multiple test connections. In addition, it does not implement support for WebSocket, which cannot be used in the test scenario of MQTT over WebSockets.
MQTT Box is an MQTT client tool developed by Sathya Vikram, originally only used in Chrome for browser expansion and installation. After rewritten for open source, it becomes a desktop-side cross-platform independent software.
Project address:GitHub MQTTBox
Download link: http://workswithweb.com/mqttbox.html
MQTT Box has the following features:
MQTT Box also adopts Electron cross-platform technology. The interface is simple and direct, and supports multiple clients to be online at the same time. However, the interaction and messaging between clients is still inconvenient. MQTT Box is a worthwhile MQTT client tool with the powerful cross-platform features of Chrome combined with simple load testing.
Mqtt-spy is part of Eclipse Paho and Eclipse IoT, which runs on top of Java 8 and JavaFX by directly launching JAR files. Mqtt-spy has a good way of interaction to show the basic MQTT publish/subscribe mechanism.
Project address: GitHub mqtt-spy
Mqtt-spy has the following features:
Mqtt-spy does not provide a separate installation package, which need to install the Java runtime environment before using it. But after launching, mqtt-spy has a friendly hands-on experience, and the boot guide feature is eye-catching. MQTT newbies can easily connect to the public MQTT Broker using mqtt-spy for exploration. The function interface of mqtt-spy is slightly complicated, but after familiar with the function of each component, it will become a development and debugging tool. It is also worth mentioning that the performance and stability of mqtt-spy are poor. It is also possible that the version used by the author is the latest beta version. After connecting multiple brokers, there are frequent crashes and suspended animations.
MQTT Lens is a Chrome extension tool that can be installed from the Chrome Web Store. MQTT Lens interface is very compact and provides basic publish and subscribe functionality.
Download link: Chrome Web Store
MQTT Lens has the following features:
MQTT Lens is simple enough, and provides the fundamental MQTT and MQTT over WebSocket connectivity to quickly get started.
