About this application
MQTT5 Explorer is a Linux desktop application built to interact with MQTT5 brokers and visualize topic hierarchies. It presents broker data in a tree structure, allowing users to expand nodes and observe incoming messages and state changes dynamically. The interface focuses on organizing topics visually rather than through flat text logs, which helps in navigating complex deployments with numerous nested namespaces and properties.
The tool is licensed under the GPL-3.0-only terms and operates strictly as a client application requiring a separate broker to connect to. It processes MQTT5 specific features such as user properties, subscription identifiers, and reason codes within the message inspection view. Users can publish messages to specific tree nodes and monitor retained messages or topic statistics directly from the graphical workspace.
