Project mention: Introducing Kafbat UI: Simplify Kafka Management with a Modern UI | dev.to | 2025-01-17
That’s why we, the core contributors to the original UI for Apache Kafka, decided to fork the project and continue its development. You can easily find it at Kafbat UI. So far, we’ve released two versions and introduced significant improvements, including enhanced smart filters, metrics polling, ACL management, and numerous CVE fixes.

Very nice to see JReleaser here on HN! I'm very happy with it, using it for publishing releases of kcctl (a command line client for Kafka Connect written in Java, compiled and published as native binaries for Linux/MacOS/Win via GraalVM). Here's the config, in case folks are looking for an example: https://github.com/kcctl/kcctl/blob/main/pom.xml#L430-L530. Releases are triggered by running a parameterized workflow (taking the version to be released) on GitHub Actions.
A big shout-out to Andres Almiray, the maintainer of JReleaser, who has always been super-fast to answer any questions and help to sort out issues when I ran into them.
