MQTT Explorer is a comprehensive MQTT client that provides a structured overview of your MQTT topics and makes working with devices/services on your broker dead-simple.

• Visualize topics and topic activity
• Delete retained topics
• Search/filter topics
• Delete topics recursively
• Publish topics
• Plot numeric topics
• Retain a history of each topic
• ...

The hierarchical view makes this tool so easy to use and differentiates the MQTT Explorer from other great MQTT clients like MQTTLens, MQTTBox and MQTT.fx.
This MQTT Client strives to be a MQTT swiss-army-knife, the perfect tool to integrate new services and IoT devices on your network.

Developing this tool takes a lot of effort, sweat and time, please consider rating the App on the Windows or Mac app store .
If you feel like a feature is missing or you found a bug, please leave me a comment / issue and I'll see what I can do.

This MQTT Client is optimized to handle thousands of topics and at hundreds of thousands messages per minute.

Custom subscriptions can limit the amount of messages MQTT Explorer needs to process, subscriptions can be managed in the advanced connection settings.
In very large productive environments brokers may handle an extreme load of topics, subscribing with a wildcard topic is in this scenario not advised.

Install with npm run install, build with npm run build

The app directory contains all the rendering logic, the backend directory currently contains the models, tests, connection management, src contains all the electron bindings. mqttjs is used to facilitate communication to MQTT brokers.

To achieve a reliable product automated tests run regularly on travis.

• Data model
• MQTT integration
• UI-Tests (The demo is a recorded ui test)

A mosquitto MQTT broker is required to run the ui-tests.

No personal data is processed, sent or stored.

The app sends telemetry and error reports, this enables me to quickly react on bugs/errors and understand what's going on. Responding quickly to errors is one key element in producing a reliable software product.

It basically sends: app version, processor architecture, operating system, used memory, user interactions and error stacks.

Even though the data is purely technical, an option to disable telemetry is planned. #52
