MQTT Clients

MQTT stands for MQ Telemetry Transport. It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks. The design principles are to minimise network bandwidth and device resource requirements whilst also attempting to ensure reliability and some degree of assurance of delivery. These principles also turn out to make the protocol ideal of the emerging “machine-to-machine” (M2M) or “Internet of Things” world of connected devices, and for mobile applications where bandwidth and battery power are at a premium.

Note: although there are a range of options available for developers interested in MQTT, not all of the client APIs listed below are current. Some are at an early or experimental stage of development, whilst others are stable and mature. Additionally, some may not provide full support for all of the features of the latest MQTT specification – for example, some may only support QoS 0, not include authentication, etc.

Check with the provider for the current status of your preferred language implementation; and remember to respect the licenses that different implementations are published under.
