## What it is
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

## Facets
- artifact type: library
- maturity: active
- function: message-queue, http-server, auth, middleware
- domain: iot, self-hosted, backend
- platform: go, windows, self-hosted
- tags: mqtt-broker, mqtt-v5, distributed-cluster, raft, gossip, quic, websocket, smarthome, embeddable, kafka-bridge, messaging, linux, macos, docker
