## What it is
Kafdrop is a lightweight web UI for viewing Apache Kafka topics, brokers, consumer groups, and browsing messages. It runs on Spring Boot and can be deployed as a JAR, Docker container, or in Kubernetes.

## Use cases
- inspect kafka topics and partitions in a browser
- browse kafka messages in json avro or protobuf
- monitor kafka consumer group lag
- view kafka broker and cluster status
- create kafka topics from a web ui
- debug kafka consumer offsets
- view kafka acls

## When to choose
- you need a quick, lightweight read-only view into a Kafka cluster
- you want to inspect consumer group lag and per-partition offsets
- you deploy on Docker or Kubernetes and want a simple Kafka dashboard
- you need to view messages encoded as JSON, Avro, or Protobuf

## When to avoid
- you need full Kafka cluster administration or management beyond basic topic creation
- you require a UI with heavy write/produce capabilities
- you need monitoring with alerting and metrics history rather than live inspection
