mochi mqtt, a fast, fully self contained mqtt broker that requires authentication the moment it boots.
Mochi MQTT is a fully featured, self contained MQTT broker written in Go that implements MQTT v5 and v3.1.1 for publish and subscribe messaging between devices and services. It suits Internet of Things fleets, telemetry pipelines and any application that needs a lightweight, embeddable message bus.
cloudimg ships Mochi MQTT secure by default: the broker generates a unique username and password on first boot, rejects anonymous and default connections, and exposes only the authenticated MQTT listener. The image is built on a hardened, fully patched base, ships with a paired deployment guide, and is backed by 24/7 support.
