What NanoMQ is

NanoMQ is a free, open-source MQTT broker designed for IoT edge devices and MECs. It supports MQTT 5.0, 3.1.1, and 3.1, and bridges messages from edge devices to multiple clouds. Supported protocols also include ZeroMQ, nanomsg, NNG, WebSocket, SOME/IP, DDS, and MQTT over QUIC, with configurable delivery guarantees. A SQL-based rule engine integrates with eKuiper for edge stream processing. Built-in persistence can resume uploads after a restored connection. Integration options include bidirectional NNG pub/sub bridging, event-driven WebHooks, and HTTP APIs. Security includes TLS/SSL, authentication, ACL, and HTTP authorization; the HTTP API accepts Basic or JWT authentication. NanoMQ can run on Linux, Windows, or self-hosted deployments, installed through Docker, package managers, Windows zip packages, or source builds. Basic, SQLite, MsQuic, and Full editions are each priced at $0.
