Our verdict on Mochi MQTT

Mochi MQTT is an open-source MQTT broker and server written in Go for telemetry, IoT, and publish/subscribe applications. It suits teams that want to run a broker themselves or embed broker functionality directly into a Go application. The deployment options cover a standalone binary, Docker, and an embeddable library, giving developers control over how the broker fits into an existing system.

Protocol coverage is a central strength. Mochi MQTT supports MQTT 5.0 while remaining compatible with MQTT 3.1.1 and MQTT 3.0.0 clients. It includes QoS 0, 1, and 2, retained messages, shared subscriptions, TCP and WebSocket listeners, and TLS configuration. An HTTP system dashboard and health-check listener add operational visibility, while inline client support and direct packet injection are useful for application-specific workflows. Rule-based authentication and ACL controls provide configurable access management.

The product is most suitable when MQTT is the required protocol and deployment flexibility matters. Persistence is available through hooks for Redis, BadgerDB, PebbleDB, or BoltDB, but that design places storage configuration and management with the deploying team. The self-hosted model also means teams must handle their own runtime environment. Choose Mochi MQTT for an embeddable, open-source Go broker with broad MQTT version compatibility and configurable infrastructure options. It is less suitable for buyers seeking a hosted service or a broader messaging platform beyond MQTT.
