Comparison and Conclusions
If you cannot afford commercial licenses then your options are Yahoo Kafka Manager, LinkedIn Burrow, KafDrop and Kafka Tool. In my opinion, the former is a comprehensive solution that should do the trick for most of the use-cases.
If you are running relatively big Kafka Clusters, then it is worth paying for a commercial license. Confluent and Lenses offer more rich functionality compared to the other monitoring tools we’ve seen in this post and I would highly recommend both of them.
