Kpow Confluent Control Center Kafbat UI

Adding an engineerDoes the bill stay flat when somebody joins?Yes. No change up to the 100 users included with each cluster, because the licence counts clusters and not seats. Yes. No seat charge. The unit is the platform licence rather than the user. Yes. No change. There is no licence to add anybody to.

Which clusters it reachesDoes it work against managed Kafka as well as self-managed?Yes. Ordinary Kafka client properties against self-managed Kafka, Amazon MSK, Confluent Platform and Cloud, Redpanda, Aiven, NetApp Instaclustr, Google Cloud MSK and Bufstream. No. Confluent Platform, and nothing else. Yes. Self-managed Kafka and managed services including Amazon MSK, Azure Event Hubs and Google Cloud, with cloud IAM integration.

What it needs on the brokerDoes it need nothing installed on the broker?Yes. Nothing. Kpow connects as an ordinary Kafka client over bootstrap servers, with no agent, JAR or reporter installed on any broker. No. The proprietary Confluent Metrics Reporter in the broker classpath. Yes. Nothing. It addresses a cluster with bootstrap-servers and ordinary client properties.

What it needs to runDoes it run without an external datastore?Yes. None. A single stateless container configured through environment variables, with no external database, no proxy layer and no persistent volume. No. Its own node, separate from the brokers, and Java 17. Next-generation sizing is 4 cores, 8 GB of RAM and 200 GB of storage up to 100,000 replicas. Yes. A container. The published Helm chart's example values are 200m of CPU and a 512Mi memory limit, tied to no cluster size.

GovernanceDoes it offer SSO and per-resource access control?Yes. LDAP, SAML, OpenID and OAuth2, with Okta, Microsoft Entra ID, Keycloak and AWS SSO named, plus role based access control at the global and the resource level. Enterprise. Yes. RBAC with audit logging for authentication and authorisation events. In an RBAC-enabled environment full management must be enabled rather than metrics only. Yes. RBAC scoped per resource type with regular-expression role subjects, OAuth and LDAP identity providers, and server-side masking with three policy types.

Audit defaultIs every user action recorded?Yes. Every user action on every cluster, recording who asked, what the request held and whether RBAC allowed it, readable in the UI or piped out as a webhook or a Kafka topic. Enterprise. No. Authentication and authorisation events across Confluent-managed clusters. No. Modifications only, until an operator sets the level to record reads as well.

SupportIs there a support channel under contract?Yes. Email support and an Enterprise support SLA, with priority support on Enterprise, and a community Slack channel and GitHub issues on both editions. Yes. A vendor under an enterprise licence, with quarterly patch updates for the current version only and no public issue tracker. Yes. GitHub issues, or a professional services engagement quoted rather than listed.

How you buy itIs the software free to use at any team size?No. No. Community Edition is free at up to 3 clusters and 10 users, and Enterprise is a commercial licence starting at 4,500 US dollars per cluster per year. No. Bundled inside a Confluent Platform enterprise licence, not sold separately, and no price is published. Yes. Free under Apache 2.0, with no paid tier and no seat or cluster cap on the software.

Kpow meets 7 of 8 requirements on this page.

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.

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.

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?

Both tools are marked out of 10 on the same five criteria, for a total out of 50, and every criterion counts once. Nothing sits behind a multiplier, so a total is the sum of its five marks and a reader can recompute it. The five are cost as teams grow, deployment footprint, support and maintenance, access control and audit, and multi-cluster reach, because those are the questions a Kafka interface is actually measured against after the first month: a second cluster, an access review with a date on it, an upgrade nobody owns, and a bill that moves when the team does. The widest gap between the two marks is on cost as teams grow, where Confluent Control Center marks 2 and Kafbat UI marks 10. The marks come from the same matrix used on every comparison on this site, so a tool scores the same here as it does anywhere else, and the reason behind each mark is in the card below, under Why these scores.

The dependency figures in the cards below were read on 24 September 2026 from each project’s published release artefact and matched against the NVD and GitHub advisory databases, so they move whenever a release or an advisory lands. Kpow is self-hosted as well. What a licence buys here is not a different deployment model, it is a company under contract to ship the patched build.

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.

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.

Which should you pick?

Kafbat UI scores 38 against Control Center’s 20 and is the pick for any cluster outside Confluent Platform, because Control Center’s proprietary reporter cannot be installed on Amazon MSK, Redpanda or Aiven. Control Center holds the ksqlDB and Kafka Streams views no free tool matches. Kafbat records changes but not reads by default and carries no support commitment, so a regulated team should shortlist Kpow by Factor House.

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. If the shortlist is wider than these two, the field is scored in full on the best free Kafka UI tools and on the best Kafka management tools.

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.
