Conduktor vs Kafbat UI
ComparisonsConduktor vs Kafbat UI, compared
Key takeaway
Both ship a current free tier, and they cap on opposite things: Conduktor Console Community stops at 50 users and 3 clusters, and Kafbat UI caps on nothing at all. Team Edition is 1,200 US dollars per seat per year, and Kafbat has no paid edition to move to. Console requires PostgreSQL 13 or later with a role holding ALL PRIVILEGES, where Kafbat holds no database and writes its audit trail into a Kafka topic. Kpow by Factor House is licensed per cluster at a published price.
What is Conduktor?
Conduktor is a commercial Kafka management and governance platform, sold as three separately licensed products. Console is a web interface over topics, schemas, connectors, consumer groups and access control across clusters. Gateway is a proxy between clients and brokers that enforces encryption, data masking, quota policy and multi-tenancy at the wire level. A Schema Registry Proxy carries its own tier.
Gateway is what makes this a different category of product rather than a smarter dashboard: field-level encryption with no client change, virtual topic filtering with no stream processor behind it, and a backend cluster failover applications never notice. It is also the only thing on either side of this comparison that sits in live client traffic. The company has been SOC2 Type II certified since 2023, and group-level RBAC, topic policies, unlimited audit logs and data masking all land in Team Edition rather than Enterprise, so the governance layer starts at a published price.
What is Kafbat UI?
Kafbat UI is a free, Apache 2.0, self-hosted web dashboard for observing and managing Kafka clusters, deployed as a container. There is no paid edition, no seat cap, no cluster cap and no source-available restriction on production use. 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. Kafbat has shipped v1.0.0 through v1.5.0, the most recent on 20 April 2026.
- Access control: permissions across cluster configuration, topics, consumer groups, schemas, Connect, connectors, ksqlDB and ACLs, with subjects matched by regular expression.
- Masking: three server-side policy types, applied per cluster.
- Audit: a log built into the product.
- Commercials: professional services around the open-source product, rather than a paid edition.
The predecessor repository is not archived, carries no pause notice and points at no successor, and it holds roughly five times the audience of the fork: 12,272 stars against 2,642. A search for Kafka UI lands on the dormant one.
What is the official 2026 pricing of Conduktor and Kafbat UI?
Both are free to start, and the two free tiers are not the same shape. Console Community is free at 50 users and 3 clusters, and single sign-on at no cost is unusual in this category. Kafbat UI is free at any number of users on any number of clusters, with nothing held back from the open release.
The difference appears at the fifty-first user or the fourth cluster. That is where Conduktor moves to Console Team Edition at 1,200 US dollars per seat per year, or 125 US dollars per seat per month billed monthly. Kafbat’s answer at fifty seats is the same container. Past Console the ladder stops being published: Gateway Enterprise is licensed per cluster with a three-cluster minimum, and three of the five purchasable tiers are contact-only. The free side has a price too. Kafbat publishes no support commitment in the software and no price for any of its professional services, so the cost of supported use is a negotiation rather than a number.
Where does each one run out?
Console requires a PostgreSQL database to hold its own state, version 13 or later, and it is not optional. On RDS the constraint is tighter: only engine versions 14.8 and later, or 15.3 and later, will work. The connection role has to hold ALL PRIVILEGES on that database, because Console creates, updates and deletes its own schemas and tables, so a least-privilege role is not an option.
- Resources: 2 CPU and 3 GB of RAM for Console, plus 2 CPU and 4 GB for Gateway.
- Latency: Gateway adds 2 to 10 milliseconds per message and is a single point of failure in live traffic.
- Azure: Event Hubs is reachable over Kafka protocol compatibility, but Azure’s native Schema Registry is not integrated.
- Directory: Active Directory needs a specific LDAP search filter, or the default configuration returns an invalid user error.
Kafbat’s audit trail is where its governance claim gets tested, and the defaults are the small print. The level switch defaults to recording modifications only, so who read something is not captured until an operator raises it.
- Audit topic: defaults to a single partition, and must not be compacted, because records carry no key.
- Masking: documented as protecting what the Messages page displays, which is a presentation control.
- Releases: four months with no tag by the end of August 2026, against five tags in 2025, while commits kept landing.
- Dynamic config: the setup wizard writes inside the container and overwrites the file in full, so UI changes are lost on restart without a volume.
Which should you pick?
Pick Conduktor if:
- the team is 50 people or fewer on 3 clusters or fewer
- a regulator or a customer contract makes the audit trail non-negotiable
- encryption or masking has to be enforced below the application
- topic creation is being handed to product teams inside policy guardrails
Pick Kafbat UI if:
- the cluster count is going up faster than the headcount
- the team can own a container and read an issue tracker
- the governance you need is who may act inside the tool, not policy on the wire
- the cluster inventory and access model belong in source control
One thing is worth checking before either decision. Both expose a Model Context Protocol endpoint onto a production cluster: Kafbat shipped an MCP server in v1.3.0 in July 2025, and Conduktor lists MCP workflows on its free Console card. Kafbat’s MCP documentation covers the enable flag, the SSE endpoint and two client setups, and describes no interaction between that endpoint and its role-based access model. A tool’s own permissions are not the same thing as the cluster’s own authorisation model, and an agent endpoint is a new subject on both.
Kpow: priced per cluster, not per seat or a quote you have to ask for
Conduktor and Kafbat UI both leave the real number unanswered until something else happens. Conduktor’s Team Edition is 1,200 US dollars per seat per year, so the bill moves the moment a fifty-first engineer needs a login, whatever the cluster count is doing. Kafbat UI’s software costs nothing at any seat or cluster count, but the moment support is needed the price becomes a services engagement with no number published anywhere, so the free side carries a cost too. Kpow by Factor House is licensed per cluster at a published price instead: one stateless container with no external database and no persistent volume, reaching up to 12 clusters from a single instance, and sitting beside the cluster rather than inside its data path.
A price you can look up before you commit to it is worth comparing against one you can’t. See what Kpow actually charges for the clusters you run, not the people who log in.
