Kafdrop

Kafdrop is an Apache 2.0 licensed project, like Apache Kafka itself, so it’s won’t cost you a penny. Kafdrop does an amazing job of filling the apparent gaps in the observability tooling of Kafka, solving problems that the community has been pointing out for too long. The Kafdrop web UI project is hosted on GitHub at obsidiandynamics/kafdrop. (I sure would) It's actually surprisingly easy to configure Kafdrop for a SASL/SSL/SSL locked-down cluster.
