Meet your
Kafka workspace.
From the first event to the next operational decision.
Explore what KUI puts within reach.
The whole cluster. In focus.
Move between environments without losing context. Read broker health, replica sync, throughput, storage, and consumer lag from one console.
- Multi-cluster navigation
- Broker topology and configuration
- Traffic, storage, and replica health
Find the event that matters.
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.
- String, JSON, Avro, JSON Schema, and Protobuf
- Field filters and advanced CEL expressions
- Pagination, infinite scroll, and message tracking
Turn lag into a plan.
See members, assignments, and lag per partition. Preview proposed offset changes, review the impact, and apply the exact plan you approved.
- Group state and partition lag
- Guided offset reset with plan tokens
- Offset and group administration
Know what your topics are doing.
Inspect partitions, consumers, and configuration. Create topics, expand partitions, update settings, and preview destructive operations before confirming.
- Topic search and inspection
- Retention and partition configuration
- Guarded empty and delete operations
Replay the original. Keep the context.
Copy ranges between topics without decoding or transforming records. Original keys, values, and headers stay intact. Read the receipt to see what was actually written.
- Explicit per-partition offset ranges
- Original bytes and headers
- Read and written counts in the receipt
Make the contract visible.
Browse subjects and versions, inspect definitions, register schemas, and test compatibility in the same workspace as your Kafka records.
- Avro, JSON Schema, and Protobuf
- Subject versions and definitions
- Compatibility checks and registration
Keep the pipeline moving.
Read connector and task health, inspect configuration, and pause, resume, or restart connectors without switching tools.
- Connector and task states
- Configuration inspection
- Pause, resume, and restart controls
Query with the topology in view.
Explore streams, tables, and persistent queries. Execute statements and follow results with the context of your cluster still in reach.
- Streams, tables, and queries
- Statement execution
- Plans for destructive statements
See the signal. Take the next step.
Follow live alerts, filter the feed, and acknowledge events. Read-only mode, permissions, masking, and audited operations keep the right guardrails close.
- Live cluster notifications
- Filter and acknowledge events
- Form/OIDC, RBAC, CSRF, and audit records
