Kafka,
in focus.
Your clusters. Your records. Your next move.
KUI brings Kafka operations into one clear view.
Inspect/Filter/Replay/Operate
Less switching.
More understanding.
From the health of a cluster to the contents of a single event. Keep the whole picture in reach.
Cluster health
Move between environments without losing context. Read broker health, replica sync, throughput, storage, and consumer lag from one console.
ExploreRecord explorer
Seek to an offset or timestamp. Decode the payload. Filter down to a field. Follow a record across topics, or publish a new one when you need to test a flow.
ExploreConsumer groups
See members, assignments, and lag per partition. Preview proposed offset changes, review the impact, and apply the exact plan you approved.
ExploreFind the signal
inside the stream.
Read the payload, not just the bytes. Filter decoded JSON, Avro, JSON Schema, and Protobuf fields. Seek to a timestamp. Follow the record that explains the problem.

A preview before
the point of no return.
Risky changes deserve a clear decision. KUI uses plan → token → confirm workflows for destructive operations, alongside read-only mode, authentication, and role-based permissions.
Understand consumer offset plansChoose the change
Select the topic and target offsets.
Review the plan
See current and proposed positions per partition.
Apply with intent
Confirm the exact plan, then inspect the receipt.
Your Kafka.
Your infrastructure.
Try the complete Docker playground, or build and publish images for your own environment.
git clone https://github.com/worxbend/kui.git
cd kui
deployment/quickstart/quickstart.shThen open localhost:8090/ui/
KUI is pre-1.0. Images are built from source. Authentication is disabled in the local demo.
