NanoMQ is an ultra-lightweight, high-performance MQTT broker and messaging bus written in C for IoT/IIoT edge computing and software-defined vehicles. Built on NNG's asynchronous I/O with an actor-model architecture, it supports MQTT 3.1.1/5.0, bridging, rule engines, and message persistence.

Use cases

• run a lightweight mqtt broker on an edge device
• broker mqtt messages between iot sensors and the cloud
• bridge mqtt data from edge to multiple cloud services
• deploy an mqtt broker in docker for pub/sub messaging
• handle mqtt traffic on multi-core embedded hardware
• persist mqtt messages offline and resume upload when reconnected
• use mqtt messaging in a software-defined vehicle

When to choose

• you need a fast, low-footprint MQTT broker for edge or embedded devices
• you want MQTT 5.0 support with bridging, persistence, and a rule engine
• you need good SMP/multi-core performance compared to Mosquitto
• you want a POSIX-portable, pure C broker for ARM or x86 edge platforms

When to avoid

• you need a full-featured enterprise MQTT cluster with horizontal scaling (consider EMQX)
• you only need a simple single-core broker and Mosquitto suffices
• you need non-MQTT messaging protocols beyond ZeroMQ/NNG/WebSocket support
• you want a managed cloud MQTT service rather than self-hosting
