NanoMQ

What NanoMQ is

NanoMQ is a free, open-source MQTT broker for IoT edge devices and MECs. It supports MQTT 5.0, 3.1.1, and 3.1, and can bridge messages from edge devices to multiple clouds. Its other protocol support includes ZeroMQ, nanomsg, NNG, WebSocket, SOME/IP, DDS, and MQTT over QUIC, with configurable delivery guarantees. A SQL-based rule engine supports edge stream processing, with integration described for eKuiper. Built-in persistence can resume uploading when a connection is restored. Integration options include bidirectional data bridging with NNG pub/sub flows, event-driven WebHooks, and HTTP APIs. Security options include TLS/SSL, authentication, ACLs, and HTTP authorization; the HTTP API accepts Basic or JWT authentication, and its documentation lists admin/public as default credentials. NanoMQ is self-hosted and can be installed through Docker, Linux package managers, Windows zip packages, or a source build. Its free editions—Basic, SQLite, MsQuic, and Full—have different feature sets. Windows documentation lists MQTT, TLS/SSL, WebSocket, MQTT-over-TCP bridging, APIs, rules, and WebHooks as supported, but QUIC is unsupported there. In the Linux deployment table, AWS bridging, SOME/IP gateway, and DDS gateway are unavailable in all four listed editions.
