A simple web-based viewer to monitor messages on topic(s) in Kafka.

Connects to Kafka via a WebSockets based proxy (using kafka-proxy-ws).



  • Monitor multiple Kafka topics
  • Receive Kafka messages in real-time

Quick Start

  1. Ensure docker is installed and running.

  2. Run the following commands:

$ docker pull jchen86/kafka-topic-viewer
$ docker run --rm -it -p 8080:8080 -p 9999:9999 \
             -e KAFKA_URL=http://your-kafka-url:port \
             -e SERVE_STATIC=true \

Building the Docker image

  1. Run npm build on client directory
$ cd client
$ npm run build
  1. Run docker build on project root directory
$ cd ..
$ docker build -t jchen86/kafka-topic-viewer .

Running from source

  1. Configure the Kafka URL in server/config.js. Default is localhost:9092.

  2. Start the Proxy server

$ npm install && npm run start
  1. Configure the topic names to monitor in client/src/app/config.js

  2. Start the client app

$ cd client
$ npm install && npm run serve

Kafka Topic Viewer should now be live on your server at port 3000.
