  First-party HiveMQ client libraries and tools, verified against the HiveMQ
  GitHub organization and Maven Central. HiveMQ's official developer surface is
  JVM-centric (the broker and its tooling are Java); the MQTT client library and
  the MQTT CLI are the two primary first-party consumable packages. For other
  languages HiveMQ documents the use of standard third-party MQTT clients
  (e.g. Eclipse Paho), which are not first-party and are not listed here.
