## What it is
MQTT Explorer is a cross-platform desktop MQTT client built with Electron and TypeScript that visualizes broker topics in a structured hierarchical tree. It supports publishing, diffing messages, plotting numeric data, and managing retained topics across thousands of topics at high message rates.

## Use cases
- browse and visualize mqtt broker topics
- debug iot devices publishing to an mqtt broker
- delete retained mqtt topics
- plot numeric mqtt topic values over time
- inspect and publish mqtt messages with a gui
- manage smart home mqtt topic tree

## When to choose
- you need a visual, hierarchical overview of an mqtt broker's topics
- you are integrating IoT devices or services with MQTT and want a swiss-army-knife debugging tool
- you need to plot or diff MQTT message payloads
- you want a polished desktop client for Windows, Mac, or Linux

## When to avoid
- you need a headless or CLI MQTT client for automation scripts
- you want a lightweight client for embedded devices
- you need a web-based or multi-user MQTT dashboard

## Facets
- artifact type: application
- maturity: active
