Confluent Control Center vs Kafbat UI
ComparisonsConfluent Control Center vs Kafbat UI, compared
Key takeaway
Control Center is a component of Confluent Platform and needs the proprietary Metrics Reporter in the broker classpath, so it cannot watch Amazon MSK, Redpanda or Aiven. It holds two things no free tool matches: its Kafka Streams topology view and its ksqlDB development workflow. Kafbat UI is Apache 2.0 with no seat or cluster cap, though it records changes but not reads until an operator sets the audit level to ALL, and no support commitment stands behind it. Kpow by Factor House is licensed per cluster at a published price.
What is Confluent Control Center?
Control Center is the web management and monitoring interface bundled with Confluent Platform, Confluent’s commercial Kafka distribution. It is closed source, licensed as part of that distribution, and not sold on its own. One dashboard covers brokers, topics, consumer groups, Kafka Connect workers, Schema Registry, ksqlDB and Kafka Streams topologies. It requires the proprietary Confluent Metrics Reporter in the broker classpath, which is a file somebody has to put on the brokers rather than a policy a support ticket can relax.
- Legacy architecture: shipped with Confluent Platform 7.x and earlier, running metrics through a Kafka Streams pipeline.
- Next generation: Prometheus-based, generally available with Confluent Platform 8.0 in May 2025.
- Current line: 2.6.x, with Java 17 as a minimum, deployed on its own node separate from the brokers.
- Ownership: IBM completed its acquisition of Confluent in March 2026.
What is Kafbat UI?
Kafbat UI is a free, open-source web dashboard for observing and managing Kafka clusters, deployed as a single container for the whole team. It is Apache 2.0, with no source-available restriction on production use, and it addresses a cluster the way any Kafka client does, through bootstrap-servers and ordinary client properties.
The naming is what most readers get wrong, and it matters because you may have typed the old name. Kafbat UI is the maintained continuation of the Provectus kafka-ui project, carried forward by contributors who were there from that project’s inception. The predecessor is dormant: its last release, v0.7.2, landed in April 2024 and its last commit that July. It still carries roughly five times Kafbat’s stars, which is why search keeps pointing at the abandoned repository. Kafbat itself has kept releasing, with v1.0.0 in March 2024 and v1.5.0 on 20 April 2026, and the company sells professional services rather than a paid edition.
What is the official 2026 pricing of Confluent Control Center and Kafbat UI?
Control Center has no price of its own, because it is not sold on its own. The unit is a Confluent Platform licence, so what you buy when you want this interface is a distribution, and it cannot be bought for a cluster somebody else runs. Beyond the base licence, Control Center, multi-tenancy support and encryption each carry cost.
Kafbat’s software costs nothing, with no seat cap and no cluster cap. The money is in services: architecture review, custom UI implementation, performance and scaling support, security and compliance work, and 24/7 enterprise support, each quoted on request. No support commitment stands behind the software itself. Neither of these bills by the seat, so headcount is the wrong axis to compare them on: a team of five and a team of fifty pay the same on both sides. One bill moves with the platform contract and the topology underneath it, and the other does not move at all, with the operator’s own time as the second half of what it costs.
Where does each one run out?
Control Center’s limits are structural before they are operational. It cannot monitor Amazon MSK, Redpanda or Aiven at all, and MSK’s native IAM authentication is not supported, so a mixed estate needs a second tool for everything that is not Confluent Platform.
- Single sign-on: SAML is not supported for self-managed deployments, and OIDC is the only protocol on Confluent Platform.
- RBAC: in an RBAC-enabled environment you cannot send metrics only, because full management has to be enabled.
- Legacy interceptors: roughly 50 internal topics added to broker metadata.
- Upgrades: legacy to next generation is a migration. Historical metrics do not carry over, and 7 to 15 days in parallel is recommended.
Kafbat’s exposure is organisational rather than technical, and the release cadence is where it shows: five tags across 2025, then v1.5.0 in April 2026 and none since, against commits still arriving in August 2026. Response times, escalation and fixes come from a services engagement.
- Audit level: defaults to
ALTER_ONLY, so who read a payload is not captured until an operator setsALL. - Audit topic: must not be compacted, because records carry no key, and its partition count defaults to 1.
- Masking: covers what the Messages page displays, per cluster and pattern-driven.
- Dynamic config: with
DYNAMIC_CONFIG_ENABLEDset, anything configured through the UI is lost on restart without a mounted volume.
Which should you pick?
Keep Control Center if:
- you are on Confluent Platform and Kafka Streams topologies are part of how the team works
- ksqlDB development integration is a requirement
Take Kafbat UI if:
- the cluster is MSK, Redpanda, Aiven or plain Apache Kafka
- Control Center is being used as a topic and consumer-group console rather than for topologies
- the licence rather than a feature gap is what is driving the move
If the cluster is not Confluent Platform, the choice is already made and no feature comparison will change it, because the Metrics Reporter cannot go on brokers whose classpath you do not control. Replacing Control Center with an open-source Kafka UI where topologies matter loses a view no free tool restores, so the work in front of you is replacing a capability rather than an interface. On the audit question both have a trail, and what each records is decided differently: Control Center logs authentication and authorisation events, and Kafbat records modifications until somebody sets the level to ALL, which belongs in the deployment manifest rather than in somebody’s memory.
Kpow: the reach a distribution’s own console doesn’t have
Control Center and Kafbat UI share the same blind spot from opposite directions. Control Center only ever watches Confluent Platform, because the proprietary Metrics Reporter it needs cannot go on brokers you don’t control, so it cannot monitor Amazon MSK, Redpanda or Aiven at all. Kafbat UI reaches any of those other clusters, but no support commitment stands behind the software itself, only a services engagement quoted on request. Kpow by Factor House is self-managed tooling that runs on top of the cluster you already have, hosting no broker and licensed per cluster at a published price. One stateless JVM container reaches self-managed Kafka, MSK, Confluent Cloud, Redpanda, Aiven and Instaclustr, covering ground a distribution’s own console can’t follow.
One interface across a topology that outgrew its distribution is worth seeing directly. Point Kpow at whichever of those clusters you run.
