Kafma Docs
Kafma is a desktop Kafka client and IDE built to keep the consume–inspect–produce loop in one workspace and clone remote topics—with their schemas and optional field masking—into a local cluster for testing.
Kafma automatically decodes Avro and Protobuf, replays or forwards messages, and lets you draft, diff, and validate schemas before publishing. Use the same app to work with Standard or AWS Glue schemas, manage Kafka Connect connectors, inspect consumer lag and its history, reset offsets, and connect to self-hosted Kafka, Confluent Cloud, or Amazon MSK.

What you can do with Kafma
Producer and consumer, one tab
Consume, inspect, edit, and produce messages without switching views.
Decode, replay, and forward messages
Decode Avro and Protobuf automatically, then replay, forward, or export what you find.
Edit schemas like code
Draft a version, diff it against the live one, and check compatibility before publishing.
Replay prod bugs on your laptop
Clone topic configuration, schemas, and messages locally—with optional field masking.
Diagnose a consumer that fell behind
Inspect lag and pending records, keep session history, and monitor groups in the background.
Manage and troubleshoot connectors
Configure Connect, edit connectors, diagnose failed tasks, and inspect offsets and sink lag.
Work with AWS Glue schemas
Configure credentials and IAM permissions, manage versions, and read and write Glue records.
Create and configure topics
Start from a preset, or set partitions, retention, and cleanup policy yourself.
