Comqtt is a lightweight, high-performance MQTT broker written in Go supporting MQTT v3.0, v3.1.1, and v5.0. It can run as a standalone server or be embedded as a Go library, with distributed clustering via Gossip and Raft, pluggable auth/storage backends, and a built-in web dashboard.

Use cases

• run an mqtt broker for iot devices
• self-host an mqtt server for smart home projects
• embed an mqtt broker in a go application
• build a distributed mqtt cluster with raft consensus
• authenticate mqtt clients against mysql or postgres
• bridge mqtt messages to kafka
• monitor mqtt broker traffic via a web dashboard

When to choose

• you need an embeddable MQTT broker in Go
• you want MQTT v5 support with clustering on a lightweight stack
• you need pluggable auth backends like Redis, HTTP, MySQL, or PostgreSQL

When to avoid

• you need a battle-tested broker with a large ecosystem like Mosquitto or EMQX
• you require a rule engine or enterprise features not yet implemented
• you need non-Go tooling or managed MQTT services
