HiveMQ MQTT Broker

The Trusted Enterprise-Grade MQTT Broker

At the heart of the HiveMQ platform is the MQTT broker, an event-driven messaging platform designed for the fast, efficient, and reliable movement of data to and from connected IoT devices. The HiveMQ broker is 100% compliant with the MQTT protocol and purpose-built for the instant, bi-directional push of data between IoT devices and enterprise systems.

HiveMQ MQTT Platform for Moving IoT Data

HiveMQ Broker is a key component of the HiveMQ platform and is designed for fast, efficient movement of data at scale.

HiveMQ Platform Architecture Overview

Key Features of HiveMQ Broker


Seamless and reliable data communication is essential to building dependable MQTT-based processes, helping businesses optimize operational efficiency, minimize disruptions, and safeguard their reputation for sustained success. The HiveMQ MQTT broker delivers IoT data with enterprise-grade reliability for mission-critical applications.

Zero message loss

  • Persistent messaging by storing all messages to disk 

  • Disk replication and offline message queuing 

  • True quality of service (QoS) support

Reliable communication

  • Automatic throttling if needed, to prevent cluster overload

  • Dynamic queuing across clusters to ensure even load distribution

  • Messages are retained and stored on disk

No single point of failure

  • Masterless cluster architecture

  • Zero downtime upgrades with automatic spawning

  • Cluster can grow and shrink at runtime without losing availability


Scalability ensures that MQTT brokers can handle the increasing number of device connections and messages without latency issues. By adopting the HiveMQ MQTT broker, businesses can scale to millions of connected devices and tens of thousands of messages per second, establishing a robust foundation for long-term growth and success.
