[Their website](https://www.cirrus-link.com/mqtt-software-for-iiot/#) says you’re limited to 50 and 250 clients in the standard and plus versions, respectively. ---

Yes, other MQTT brokers are supported. I think they need to support at least QoS 1. You should contact Cirrus Link for more details and verification. ---

because of performance and memory limitation they limit number to 50. I recommend if need more than 50 client use dedicated MQTT server other wise you face some performance problem. Cirrus Link sell a in depended MQTT server for that called Chariot MQTT Server. [https://www.cirrus-link.com/iiot-mqtt-servers/](https://www.cirrus-link.com/iiot-mqtt-servers/) ---
