Kafka Dev UI

If any Kafka-related extension is present (e.g. quarkus-smallrye-reactive-messaging-kafka), the Quarkus Dev UI is extended with a Kafka broker management UI. It is connected automatically to the Kafka broker configured for the application.


With the Kafka Dev UI, you can directly manage your Kafka cluster and perform tasks, such as:

  • Listing and creating topics

  • Visualizing records

  • Publishing new records

  • Inspecting the list of consumer groups and their consumption lag

Kafka Dev UI is part of the Quarkus Dev UI and is only available in development mode.
