Confluent Control Center vs Kafdrop
ComparisonsConfluent Control Center vs Kafdrop, compared
Key takeaway
Control Center needs Confluent’s own reporter configured on every broker, so it does not reach Amazon MSK, Redpanda or Aiven, and it carries no published price of its own. Kafdrop connects to any Kafka from 0.11.0 and is free under Apache 2.0, but it has no authentication, no RBAC and no SSO — its README documents an NGINX basic-auth workaround instead, and its newest tagged release is still 4.2.0, from July 2025. Kpow by Factor House is licensed per cluster at a published price.
What is Confluent Control Center?
Control Center is a web management and monitoring interface bundled with Confluent Platform, Confluent’s commercial Kafka distribution. It is closed-source and licensed as part of that platform. One dashboard covers brokers, topics, consumer groups, Kafka Connect workers, Schema Registry, ksqlDB and Kafka Streams topologies.
Control Center 2.0.0 and later takes its system health metrics through Confluent’s proprietary Telemetry Reporter, configured on every Kafka broker and KRaft controller, and the older Confluent Metrics Reporter serves Control Center (Legacy) only. Either way the reporter is broker-side, so standing Control Center up is a change to the brokers rather than to the tool, and that change cannot be made on Amazon MSK, Redpanda or Aiven.
- Architectures: a legacy Kafka Streams metrics pipeline on 7.x and earlier, and a Prometheus-based next generation from Confluent Platform 8.0 in May 2025.
- Current line: 2.6.x, with 2.6.0 released on 14 July 2026, and Java 17 as a minimum.
- Placement: it must not sit on the same node as Confluent Platform, because Confluent packages on the host cause class-loading conflicts.
What is Kafdrop?
Kafdrop is an open-source Kafka web UI built on Spring Boot, licensed Apache 2.0, hosted at obsidiandynamics/kafdrop and maintained by the Obsidian Dynamics team. It runs as a stateless Java process against the standard broker protocols with no separate datastore. Requirements are Java 17 or newer and Kafka 0.11.0 or newer, or Azure Event Hubs, and the UI serves on port 9000. A ZooKeeper connection has not been required since 3.10.0.
- view brokers, and browse topics and partition state
- inspect messages in JSON, plain text, Avro and Protobuf
- view consumer groups with combined and per-partition lag
- create topics, and view ACLs
The repository is not archived, carries 6,154 stars and 46 open issues, and last received a push to master on 27 August 2026. The newest tagged release is still 4.2.0, published on 31 July 2025, so the community features merged in August 2026 sit in no published image.
What is the official 2026 pricing of Confluent Control Center and Kafdrop?
Control Center carries no published price. It is bundled with Confluent Platform under an enterprise licence, so the unit is the platform licence rather than a cluster or a seat, and there is nothing to buy for a cluster somebody else runs. Control Center, multi-tenancy support and encryption each carry additional cost. That licence includes quarterly patch updates for the current version only, and the Platinum support tier is not available for this product.
Kafdrop costs nothing to license: Apache 2.0, a single tier, no commercial edition and no supported tier. The whole cost is operator time, and the part that shows up later is that there is nobody to escalate to. The line a platform team actually feels is infrastructure. Control Center wants dedicated nodes: 4 cores, 8 GB of RAM and 200 GB of storage, preferably SSD, for clusters up to 100,000 replicas, and 8 cores with 16 GB above that, with the storage guidance assuming 15 days of metrics retention. Kafdrop is one process on a small heap.
Where does each one run out?
Control Center runs out at the edge of the distribution it ships with. It cannot monitor Amazon MSK, Redpanda or Aiven, and MSK’s native IAM authentication is not supported. SAML SSO is not supported on self-managed deployments, where OIDC is the only protocol, so a SAML-only identity provider has no supported path in.
- RBAC: all or nothing. Metrics-only is not a configuration, and the scale limit is 10,000 rules per cluster.
- Reduced infrastructure mode: keeps the management services and supplies no metrics, no monitoring data and no alerts.
- Consumer lag: not tracked for consumers that call
assign()rather thansubscribe(), and Metrics API values do not update during a rebalance. - Kubernetes: Horizontal Pod Autoscaling is not supported for its pods, and UI changes apply straight to cluster state rather than through a Git-managed manifest.
Kafdrop runs out at governance, and the README states the position plainly: it does not implement an authentication mechanism to restrict user access, and documents an NGINX basic-auth workaround instead. There is no RBAC and no SSO, so Kafka’s own authorisation model is the only thing between a user of the UI and the cluster.
- Write operations: exposed, with no read-only mode. The pull request adding that toggle has been open since 30 November 2020.
- Scope: the authentication request was opened in January 2026 and closed as not planned six weeks later.
- Reach: no multi-cluster management, no message search by key or value, and deserialisation set per topic by hand.
- Scale: 5,566 consumer groups pushed load times past 30 minutes, and the UI loaded in under a minute with that enumeration disabled.
KRaft is the thing to settle first, because Apache Kafka 4.0 is the first major release to operate entirely without ZooKeeper. Three KRaft failure reports were all closed as not planned, the last in April 2025, and none has been filed since.
Which should you pick?
Pick Control Center if:
- you are on Confluent Platform and staying on it
- Kafka Streams topology visualisation or ksqlDB development is what you want to see
- there are nodes to spare to run the console on
Pick Kafdrop if:
- what you need is a viewer on a cluster you already hold credentials for
- everybody using it holds those credentials anyway
- the deployment should hold no state and be removable by deleting a container
For most readers neither case applies, because neither tool is available to everybody. Control Center is unavailable to anyone not running Confluent Platform, and Kafdrop is unavailable to anyone who cannot hand every user of the console the credentials the container was given. If the console has to reach a cluster somebody else runs, neither of these is the answer.
Kpow: role-based access, without a distribution or a workaround
Control Center and Kafdrop solve access control by picking an extreme. Control Center’s RBAC only exists inside a Confluent Platform licence, so the governance arrives bundled with a distribution you have to buy first, and it never reaches Amazon MSK, Redpanda or Aiven. Kafdrop has no access control of any kind: no authentication, no RBAC, no SSO, just an NGINX basic-auth workaround its own README points to instead. Kpow by Factor House is licensed per cluster at a published price and runs on top of the cluster you already have as a single stateless container with no external database, authenticating and authorising its own users through role-based access control, with no distribution required and no workaround needed.
Get the access control that’s built in, not bolted on or bundled with a distribution. Start with Kpow on that cluster.
