mosquitto2.1.2

Mosquitto routes messages between devices and applications through an MQTT broker, allowing systems that produce data to communicate with interested recipients without maintaining direct connections. Publishers send messages to the broker, while subscribers receive selected messages, separating message producers from consumers. This gives developers and system administrators a dedicated messaging layer for device-oriented communication.

The broker is designed for relatively low-bandwidth use and limited implementation effort, which suits edge networks built with sensors, simple microcontrollers, and other constrained devices. It provides the central relay in an MQTT deployment rather than acting as a general desktop application, connecting software that generates telemetry with programs that process it. Mosquitto is maintained by the Mosquitto Team and released as open-source software.

The Linux build is categorized under System Tools, runs on x86_64 (amd64) architecture, and requires snapd. Current version 2.1.2 provides the broker for developers and administrators deploying MQTT messaging in Linux-based sensor, embedded, and edge environments. Its publisher-and-subscriber model lets applications consume only the message streams relevant to them, while the broker manages the exchange between otherwise separate systems.
