The short version

  • Each has a real cost: MQTT mQTT is an open-source protocol standard with no commercial pricing; not a commercial product; Zigbee Alliance the Internet Archive's capture of the Connectivity Standards Alliance's Zigbee page on 4 January 2024 confirmed Zigbee is a protocol standard rather than a purchased product, with the Alliance's revenue coming from member dues and per-device certification fees rather than a software price list.
  • They diverge on capability: MQTT covers Publish-Subscribe, Zigbee Alliance covers Low Power.
  • Prices and features above were last checked on 30 August 2026.
