MQTTBox
MQTTBox is a free, lightweight MQTT client and test utility for macOS used by IoT developers, embedded systems engineers, and automation professionals. It provides a graphical interface for publishing and subscribing to MQTT topics, inspecting message payloads, managing multiple broker connections, and debugging MQTT-based applications and IoT networks. The app is popular among developers prototyping or troubleshooting MQTT infrastructure without needing a full IDE or terminal-based client.
AI Recommendation
1 suggestionWe could not find recent information about MQTTBox's development status or architecture support from the search results we gathered. To determine whether a native Apple Silicon build exists and is currently available, we recommend contacting the developer directly or checking their official website or repository (likely hosted on GitHub given the bundle ID pattern). Ask the developer specifically whether a native Apple Silicon build has been released, or is planned before macOS 28 ships in September 2028. If the current version you have is Intel-only, it will stop working on that release unless updated. As a contingency, consider MQTT Explorer or other actively maintained MQTT clients with confirmed native Apple Silicon support — these would allow you to migrate your subscriptions and saved connections if MQTTBox is no longer maintained.
