KafkIO - The Fast, Easy Apache Kafka™ GUI, for Engineers and Administrators

Hi there! We’re excited to announce that KafkIO has reached a major milestone! Six months and 16 versions since its first release, we feel like it deserves a mention.

KafkIO is a native, client-side Kafka GUI for Windows, macOS, and Linux. It’s designed to cover everything you’d expect from Kafka and its ecosystem—plus more:

  • Expected support for standard connectivity and security protocols
  • Compatible with cloud providers like Aiven and Confluent
  • Specialized integrations for Strimzi, Azure Event Hub, and Amazon MSK
  • Detailed cluster and broker statistics
  • Full topic and message management with flexible search capabilities
  • Automatic detection, formatting, and syntax highlighting of message types
  • View messages in raw or pretty-printed formats
  • Real-time message streaming
  • Consumer and ACL management
  • Full integration with Schema Registry
  • ksqlDB editor and KSQL support
  • Kafka Connect: fully manage connectors
  • Certificate support (PEM, X.509, PKCS12, JKS) without conversion hassles—but a built-in converter is available if needed
  • Health log for basic real-time monitoring
  • Event log to diagnose issues
  • Filterable tables and copy-friendly data
  • Portable mode for keeping the app and configuration in a single folder
  • Import, export, and reset preferences with ease
  • Intuitive pop-ups and tooltips throughout

We’re just getting started, with many more features planned!

KafkIO is highly configurable, supporting self-signed certificates, proxies, timeouts, and more. There’s no backend, Docker, or web server—it’s a traditional desktop app that works out of the box.

This is a freeware (donationware) project, built out of passion for the Kafka community.
