Kpow vs Kafbat UI
ComparisonsKpow vs Kafbat UI, compared
Key takeaway
Both are web interfaces over a cluster somebody else is running, and the choice is not governance against none. Kafbat UI is free and Apache 2.0, with no cap on clusters or engineers, and it carries role-based access control, server-side masking and an audit log in the free product, though that log records modifications only until an operator turns on read auditing. What is bought is accountability: Kafbat publishes no support commitment. Kpow by Factor House starts at 4,500 US dollars per cluster per year, with 100 users included.
What is Kafbat UI?
Kafbat UI is a free, open-source web dashboard for observing and managing Kafka clusters. It is Apache 2.0 licensed and deploys as a container rather than as an install per engineer, and there is no paid tier, no seat cap and no cluster cap on the software itself. It is the maintained continuation of the Provectus kafka-ui project, whose last release was v0.7.2 in April 2024 and whose last commit landed that July, and which still carries 12,200 stars against the fork’s audience.
- Access control: permissions scoped per resource type across eight resources, each with its own actions, and subjects matched by regular expression.
- Identity: OAuth including Google, GitHub and Cognito, plus LDAP and Active Directory.
- Masking: server-side
REMOVE,REPLACEandMASKpolicies on keys, values and named JSON fields. - Audit: a log written to a Kafka topic.
Releases run from v1.0.0 in March 2024 through v1.5.0 in April 2026.
What is Kpow?
Kpow by Factor House is engineer-facing tooling for Apache Kafka. It runs against whatever cluster you already have: self-managed Kafka, Amazon MSK, Confluent Cloud, Redpanda, Aiven and Instaclustr, and it puts Kafka monitoring, data inspection and administration behind one interface.
It is a single stateless JVM container, configured entirely through environment variables, with no external database, no sidecar and no persistent volume. Its telemetry lives in internal Kafka topics on the cluster it is already monitoring, so there is no second system to run, back up or upgrade, and one instance manages up to 12 clusters. It is licensed per cluster rather than per user, and the price is published: Kpow runs on top of a cluster somebody else is running, which is why the unit of the licence is the cluster and not the engineer.
What is the official 2026 pricing of Kpow and Kafbat UI?
Kafbat UI costs nothing to license and has no ceiling on clusters or engineers. The money in that model is a professional services engagement covering architecture review, custom implementation, performance and scaling work, security and 24/7 support, and no price is published for any of it. The software is therefore budgetable at zero, and supported use is not budgetable in advance at all.
Kpow Enterprise starts at 4,500 US dollars per cluster per year, with 100 users included, and adding an engineer does not change the bill. Kpow Community Edition is free for up to 3 clusters and 10 users, with simple user authentication and neither role-based access control nor single sign-on. The practical test has two halves: which of your two numbers is growing faster, the cluster count or the head count, and whether anybody outside your team ever has to be told who did what, and when. A team of four running two clusters under no compliance obligation is Kafbat’s case, and no pricing argument changes that.
Where does each one run out?
Kafbat’s limits are operational rather than featural. The project publishes no support commitment of its own: response times, escalation and fixes come from a services engagement negotiated separately. Governance is operator-authored and pattern-driven, so masking and access coverage is whatever somebody wrote and keeps maintaining as topics are added. RBAC for Kafka is never a switch, and here the authorship and the upkeep are yours.
- Audit level: modifications only, so who read something is not recorded until an operator turns read auditing on.
- Audit topic: defaults to a single partition, and must not be compacted, because the records carry no key.
- Masking coverage: only as complete as the patterns written for it.
- Dynamic config: anything created through the wizard is written inside the container and survives a restart only on a mounted volume.
Kpow is not a proxy either: nothing sits between producers and brokers, so nothing is enforced in the data path, and neither product’s role model reaches the broker’s own ACLs underneath it. Where Kpow’s free tier stops at 3 clusters and 10 users, the access control, masking and audit trail that come with the paid tiers are what a governed estate is usually buying.
How do you switch, or run both?
Running both is reasonable, and it costs a container and a configuration block rather than a migration, because neither tool owns cluster state. Kafbat holds no state on the brokers, so removing it changes nothing on the cluster, and declaring clusters in YAML or environment variables under source control avoids the one wizard exception entirely. Kpow is a container as well, and its telemetry lives in Kafka topics on the monitored cluster, so removing it leaves nothing behind to migrate. Coming from the Provectus project, moving to Kafbat is a change of maintainer rather than a change of tool.
Which should you pick?
Pick Kafbat UI if:
- the team is small and the cluster count is low
- nobody outside the team needs an audit answer on demand
- somebody genuinely enjoys owning the configuration
Pick Kpow if:
- somebody has to be accountable when the tool is wrong
- role-based access is wanted without a per-user bill
- the estate is mixed across MSK, Confluent Cloud, Redpanda and self-managed Kafka
- a price you can read before talking to anybody is part of the requirement
Pick neither if the requirement is written as policy enforced in the data path: that is a proxy, and a different interface on top of the cluster does not deliver it. These two are also not the whole field, and AKHQ, Redpanda Console and Conduktor sit in the same category.
Who is on the hook?
Kafbat UI carries real governance for a free product: role-based access control scoped per resource across eight resource types, with subjects matched by regular expression, server-side REMOVE, REPLACE and MASK policies on keys, values and named JSON fields, and an audit log written to a Kafka topic. It is also the maintained continuation of Provectus’s kafka-ui, still carrying 12,200 stars against the fork’s own audience.
Still, what Kafbat doesn’t carry is a guarantee. There is no support commitment behind any of it — response times, escalation and fixes all come from a services engagement negotiated separately, with no price attached. Masking coverage is only as complete as the patterns someone wrote and keeps maintaining as topics get added, and dynamic configuration created through the setup wizard lives inside the container, surviving a restart only if somebody mounted a volume for it. Kpow answers each of those directly: commercial support comes with the licence rather than a separate negotiation, data masking policies are applied by role instead of a pattern somebody has to keep current, and the whole deployment is one stateless container configured through environment variables, with no database, sidecar or volume to remember to mount.
It also reaches up to 12 clusters from one instance, and the price is published rather than negotiated: Enterprise starts at 4,500 US dollars per cluster with 100 users included, and adding an engineer doesn’t move that number. Start on Kpow and see whether it answers that ticket before you buy anything. Kafbat can show you what happened, once somebody builds a reader for it. Kpow tells you who’s on the hook before you have to ask.
