SELF-HOSTED KAFKA UIA Kafka UI built for
A Kafka UI built for
real operations.
Browse messages, diagnose consumer lag, inspect broker storage, follow dependencies, and run permission-aware Kafka operations from one Kubernetes-native web console.
PRACTICAL GUIDE
What a production Kafka UI should make easier.
A useful Kafka web UI does more than list topics. It should connect the signal you notice - lag, storage pressure, a failing connector, or a suspicious record - to the exact Kafka resource and evidence behind it.
BetterKafka keeps each cluster connection server-owned, shows partial coverage instead of turning unknown values into zero, and separates inspection from mutation. That makes the same console useful to viewers, operators, and administrators without giving every user the same power.
Message browser
Bounded record search, live tail, headers, offsets, encodings, export, compose, tombstones, and guarded republish.
Consumer lag
Group state, members, partition offsets, total lag, worst partitions, and known-versus-total coverage.
Broker operations
Leadership, replica distribution, PVC capacity, optional filesystem growth, and rebalance evidence.
Live dependency map
Applications, topics, consumer groups, brokers, and connectors with rate, lag, history, and evidence labels.
OPERATOR WORKFLOW
From signal to answer.
Select a configured cluster
Choose a stable cluster ID; bootstrap addresses and credentials never come from browser input.
Start from the strongest signal
Open health, lag, broker pressure, topology, connector state, or a message search.
Inspect the evidence
Drill into partitions, offsets, records, configuration, source coverage, and freshness.
Act behind guardrails
Use cluster capabilities, user roles, mutation plans, reasons, and receipts for supported changes.
COMMON QUESTIONS
What teams need to know.
Is BetterKafka a desktop Kafka client?
No. It is a self-hosted web application deployed into Kubernetes with a Helm chart.
Does it support Apache Kafka?
Yes. Core operations use Kafka Admin, Consumer, and Producer APIs and work with compatible Apache Kafka clusters.
Can one installation show multiple clusters?
Yes. One installation can hold up to 20 server-configured cluster entries, with isolated clients, permissions, and rate limits.
Does the browser receive Kafka credentials?
No. Kafka destinations and credentials remain deployment configuration and Kubernetes Secret references.
SELF-HOSTED KAFKA OPERATIONS
Try it on one cluster. Decide from evidence.
BetterKafka keeps the trial path as focused as the operator workflow.
