## What it is
HiveMQ Community Edition is a Java-based open-source MQTT broker fully supporting MQTT 3.x and MQTT 5, serving as the foundation of the HiveMQ enterprise messaging platform. It provides reliable publish/subscribe messaging for IoT and machine-to-machine communication.

## Use cases
- run an mqtt broker for iot devices
- connect sensors and plcs via pub/sub messaging
- stream industrial telemetry in real time
- self-host an mqtt 5 compliant message broker
- bridge iot device data to backend systems
- build machine-to-machine communication infrastructure

## When to choose
- you need a production-grade MQTT 3.x/5 broker with clustering support
- you're building IoT or IIoT systems requiring reliable pub/sub messaging
- you want an Apache-2.0 licensed broker extensible via a plugin SDK
- you need high-throughput messaging for connected devices

## When to avoid
- you need enterprise features like Data Hub, Kafka bridging, or managed cloud (commercial HiveMQ)
- your use case is general-purpose message queuing rather than MQTT pub/sub
- you need a broker in a non-JVM runtime

## Facets
- artifact type: service
- maturity: active
- function: message-queue, middleware, iot, networking, self-hosted
- domain: iot, microservices, developer-tools
- platform: jvm, self-hosted, cross-platform
- tags: mqtt-broker, mqtt5, pubsub, m2m, iot-middleware, industrial-iot, telemetry, messaging, real-time, linux, docker, kubernetes
