Zilla MQTT highlights include:

• MQTT v5 and v3.1.1 Support:
• MQTT-Kafka Proxying: Zilla maintains the MQTT client state across Kafka topics, providing all of the features and guarantees of a dedicated MQTT broker, such as Keep-Alive, Last Will and Testament, and all three Quality of Service (QOS) agreements. MQTT over WebSocket is also supported, so Zilla can deliver MQTT messages from Kafka down to a browser.
• Manage Millions of Clients: Zilla is stateless, scales out linearly, and handles MQTT to Kafka connection offloading.

Try out the MQTT-Kafka proxying guide. We also have a fun Taxi Hailing Demo that simulates IoT vehicle tracking.

Zilla is open source, so please consider starring the repo to help us improve Zilla for the IoT community!
