Mosquitto is an open-source message broker that implements the MQTT (Message Queuing Telemetry Transport) protocol, designed for lightweight, low-bandwidth communication in resource-constrained environments. Developed by the Eclipse Foundation, Mosquitto is particularly well-suited for IoT (Internet of Things) applications, where devices may have limited computing power and network capabilities. It facilitates publish/subscribe messaging, allowing multiple devices to communicate efficiently and reliably, making it ideal for scenarios where low latency and minimal overhead are critical.
With support for various platforms, Mosquitto offers ease of installation and configuration, robust security features including authentication and encryption, and scalability to handle thousands of connections. Its compatibility with multiple programming languages and libraries enhances its versatility, making it a popular choice for developers looking to build real-time applications and services in diverse domains such as home automation, industrial control systems, and telecommunication monitoring.
