From Developers to Developers

Karafka was born out of real engineering problems. Today, we run it ourselves – processing over 500 million messages every day.

Karafka Web UI

Karafka Web UI is a user interface for the Karafka framework. The Web UI provides a convenient way for developers to monitor and manage their Karafka-based applications, without the need to use the command line or third party software.

The interface, among others, includes:

  • historical metrics
  • real-time aggregated metrics
  • real-time information on resource usage
  • error details
  • performance statistics
  • Kafka topics data explorer
  • stale partitions detection (LSO hangs)
  • routing pattern matched topics subscriptions

Process messages like a Pro!

Karafka Pro includes a commercial-friendly license, priority support, architecture consultations, high-throughput data processing features, and more.

Good open source doesn't happen alone. Shape the future of Kafka processing with us.
