Live message tailing

Pick a topic and watch Kafka messages stream in real time with a clean, readable UI.

Built for real clusters

Works with local Kafka, Redpanda, and Confluent Cloud using SASL_SSL.

Developer-focused workflow

Pretty JSON, filter messages, pause the stream, clear output, and copy events instantly.

No dashboards. No clutter. Just messages.

Offsy is intentionally small. It is not a Kafka administration platform. It is the fastest way to inspect topic messages while developing and debugging.
