This article looks at the tool from a different angle: which problems it solves, when I reach for it, and what separates it from a general-purpose MQTT client.</p> <p><a href="https://github.com/koepalex/Crow-s-Nest-MQTT">Crow&rsquo;s NestMQTT</a> is a cross-platform desktop client for Windows, Linux, and macOS. I think of it as an MQTT 5 workbench rather than a broker dashboard. Its job is to help a developer move from &ldquo;messages are arriving&rdquo; to understanding the topic structure, payload, metadata, timing, and relationships between messages.</p>
