Gmqtt is a flexible, high-performance MQTT broker written in Go that fully implements MQTT protocol V3.x and V5. It offers a plugin mechanism, hooks for authentication/ACL, TLS and WebSocket support, Prometheus metrics, gRPC/REST admin APIs, Redis-backed session persistence, and an experimental clustering (federation) feature.

Use cases

• run a self-hosted MQTT broker in Go
• handle IoT device telemetry over MQTT
• build a customizable MQTT broker with auth and ACL hooks
• monitor MQTT broker metrics with Prometheus
• persist MQTT sessions across broker restarts with Redis
• manage an MQTT broker via gRPC or REST APIs

When to choose

• you need an embeddable or extensible MQTT broker in Go
• you want MQTT 3.x and 5 support with plugin-based customization
• you need WebSocket and TLS transport for MQTT clients
• you want built-in Prometheus metrics and admin APIs

When to avoid

• the project is less maintained and the author recommends careful evaluation before production use
• you need production-proven clustering - the federation feature is experimental and never used in production
• you prefer a turnkey broker with minimal configuration
• you need persistence backends other than Redis
