@ponmanikandanb there is full support for TLS and SASL in Kafdrop 3. In addition, ZooKeeper connections are no longer required, meaning that you only connect to Kafka brokers.
@ponmanikandanb no sorry, the 3.x project has been migrated to Java 11 as part of a wholesale modernisation of the codebase. We're actually using Java 10 language features, so it is not source-compatible with JDK 8.
May I suggest that you just use the Docker image if you don't want to install JDK 11?
