public_brokers
This page is an effort to list the publically-accessible MQTT brokers, often useful for testing and prototyping.
Note: none of these test brokers (except mqtt.flespi.io and myqtthub.com) carry any guarantee of service. Be sensible when using them and don't break things for others! :-)
