HiveMQ MQTT Broker provides event-driven messaging between connected devices and enterprise systems. It supports MQTT 3.1.1 and MQTT 5.0, with persistent messages stored to disk, offline queuing, and quality-of-service support.

Extensions connect to streaming services, databases, data warehouses, and security services, with Kafka, Amazon Kinesis, and Google Pub/Sub listed as examples. Security options include TLS 1.2/1.3, mutual TLS, fine-grained access controls, pluggable authentication such as OAuth 2.0 and LDAP, and audit logging. The self-managed broker can run on private, hybrid, and public clouds, with images for Kubernetes, OpenShift, and DC/OS. In evaluation mode without a valid license, it supports up to 25 client connections. HiveMQ describes the broker as intended for large-scale IoT deployments and mission-critical enterprise operations. Plans include a free option; Launch is $299 a month and Run is $499 a month.
