HiveMQ MQTT Broker
What HiveMQ MQTT Broker is
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 configurable quality-of-service support. The maker describes the broker as scaling to millions of connections and billions of messages. Dynamic clustering lets operators add or remove broker nodes while the cluster is running. Extensions connect it with streaming services, databases, data warehouses, and security services; listed examples include Kafka, Amazon Kinesis, and Google Pub/Sub. Security options include TLS 1.2/1.3, mutual TLS, fine-grained access control, 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. Without a valid license, evaluation mode supports up to 25 client connections. HiveMQ lists a free plan and a 15-day trial; Launch is $299 a month and Run is $499 a month.
