HMQ is a high-performance MQTT broker written in Go, supporting MQTT 3.1.1 with QoS 0/1, retained and will messages, WebSockets, and TLS. It offers clustering via a router service, HTTP-based auth and ACL plugins, Kafka bridging, shared subscriptions, and an HTTP API for client management.

Use cases

• run a high-throughput mqtt broker for iot devices
• cluster mqtt brokers for horizontal scaling
• bridge mqtt messages into kafka
• authenticate mqtt clients against an http backend
• serve mqtt over websockets for browser clients
• enforce per-topic acl permissions for mqtt clients
• get online/offline notifications for connected clients

When to choose

• you need a lightweight, fast mqtt broker in go
• you want kafka integration for iot message pipelines
• you need clustered mqtt with shared subscriptions
• you prefer a simple single-binary broker with config-file setup

When to avoid

• you need full mqtt 5.0 support
• you require qos 2 message delivery
• you want a broker with a large plugin ecosystem or gui dashboard
• you need enterprise-grade support and long-term vendor maintenance
