The Interface

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

Topics

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.

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.

Messages

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.

Schema registry

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

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