HiveMQ Introduction

HiveMQ is a world-class, enterprise-ready MQTT broker that provides fast, efficient, and reliable movement of data to and from connected IoT devices.

HiveMQ fully implements the MQTT protocol (the standard messaging and data exchange protocol for IoT).
Our broker is built from the ground up with maximum scalability and enterprise-grade security concepts in mind.
Through 100% compliance with the MQTT specification, HiveMQ is a worldwide leader in the professional adoption of all the possibilities the Internet of Things has to offer. As a member of the OASIS committee, the HiveMQ team has been directly involved in the creation and release of MQTT 5.0, the newest version of the MQTT protocol.
