Mosquitto

Mosquitto is an open-source software that acts as a messaging broker using the MQTT protocol, enabling devices and applications to communicate efficiently. It facilitates real-time data exchange by managing messages between sensors, devices, and services, often in Internet of Things (IoT) setups. Devices publish data to Mosquitto, and others subscribe to receive updates, all controlled through a lightweight, reliable system that conserves bandwidth. Mosquitto's simplicity and performance make it popular for building interconnected systems where seamless, low-latency communication is essential.
