UI for Apache Kafka is a free, open-source web UI to monitor and manage Apache Kafka clusters.

UI for Apache Kafka is a simple tool that makes your data flows observable, helps find and troubleshoot issues faster and deliver optimal performance. Its lightweight dashboard makes it easy to track key metrics of your Kafka clusters - Brokers, Topics, Partitions, Production, and Consumption.

Set up UI for Apache Kafka with just a couple of easy commands to visualize your Kafka data in a comprehensible way. You can run the tool locally or in the cloud.



  • Multi-Cluster Management — monitor and manage all your clusters in one place
  • Performance Monitoring with Metrics Dashboard — track key Kafka metrics with a lightweight dashboard
  • View Kafka Brokers — view topic and partition assignments, controller status
  • View Kafka Topics — view partition count, replication status, and custom configuration
  • View Consumer Groups — view per-partition parked offsets, combined and per-partition lag
  • Browse Messages — browse messages with JSON, plain text, and Avro encoding
  • Dynamic Topic Configuration — create and configure new topics with dynamic configuration
  • Configurable Authentification — secure your installation with optional Github/Gitlab/Google OAuth 2.0

The Interface

UI for Apache Kafka wraps major functions of Apache Kafka with an intuitive user interface.



UI for Apache Kafka makes it easy for you to create topics in your browser by several clicks, pasting your own parameters, and viewing topics in the list.

Create Topic

It's possible to jump from connectors view to corresponding topics and from a topic to consumers (back and forth) for more convenient navigation. connectors, overview topic settings.



Let's say we want to produce messages for our topic. With the UI for Apache Kafka we can send or write data/messages to the Kafka topics without effort by specifying parameters, and viewing messages in the list.

Produce Message

Schema registry

There are 3 supported types of schemas: Avro®, JSON Schema, and Protobuf schemas.

Create Schema Registry

Before producing avro-encoded messages, you have to add an avro schema for the topic in Schema Registry. Now all these steps are easy to do with a few clicks in a user-friendly interface.

Avro Schema Topic

Getting Started

To run UI for Apache Kafka, you can use a pre-built Docker image or build it locally.


We have plenty of docker-compose files as examples. They're built for various configuration stacks.


Configuration File

Example of how to configure clusters in the application-local.yml configuration file:

      name: local
      bootstrapServers: localhost:29091
      schemaRegistry: http://localhost:8085
        username: username
        password: password
#     schemaNameTemplate: "%s-value"
      jmxPort: 9997
  • name: cluster name
  • bootstrapServers: where to connect
  • schemaRegistry: schemaRegistry's address
  • schemaRegistryAuth.username: schemaRegistry's basic authentication username
  • schemaRegistryAuth.password: schemaRegistry's basic authentication password
  • schemaNameTemplate: how keys are saved to schemaRegistry
  • jmxPort: open jmxPosrts of a broker
  • readOnly: enable read only mode

Configure as many clusters as you need by adding their configs below separated with -.

Running a Docker Image

The official Docker image for UI for Apache Kafka is hosted here:

Launch Docker container in the background:

docker run -p 8080:8080 \
	-d provectuslabs/kafka-ui:latest 

Then access the web UI at http://localhost:8080.

Building With Docker







Liveliness and readiness probes

Liveliness and readiness endpoint is at /actuator/health. Info endpoint (build info) is located at /actuator/info.

Environment Variables

Alternatively, each variable of the .yml file can be set with an environment variable. For example, if you want to use an environment variable to set the name parameter, you can write it like this: KAFKA_CLUSTERS_2_NAME
