Why use Kafka UI?
Boost your productivity with a tool designed for developers and data engineers.
Find the topics you need
Browse all your Kafka topics in one clean view. See partitions, replication factors, and metrics instantly — no CLI required. Search, filter, and dive deep into the messages that matter.
Produce messages
Test and publish events directly from the UI. Quickly validate payloads, headers, and schemas without extra tooling.
Consume messages
Stream messages in real time. Filter by key, offset, or partition and debug event flows on the spot.
Quick connect
Connect to your Kafka cluster in seconds. Secure auth, multiple cluster support, and zero manual setup.
