Siege — Kafka Chaos Testing Tool by Kannika.io

Siege is an open-source chaos engineering tool for Apache Kafka, built in Rust.
Developed and maintained by Kannika.io — the Kafka reliability platform.

Siege lets you test Kafka resilience by simulating destructive scenarios: topic deletion, schema corruption, consumer group disruption, and policy modification. It's built for teams who run Kafka in production and want confidence before things break unexpectedly.

What is Kannika.io?

Kannika.io builds tools for Kafka observability, reliability, and chaos testing. Siege is our open-source contribution to the Kafka and chaos engineering community.
