Show HN: Self-contained Kafka demo for developers coming from RabbitMQ

[mkumm]

I'm an Elixir developer with a RabbitMQ background, currently learning C# and Kafka. To make the concepts stick, I built this self-contained demo — it gets you up and running in about 5 minutes.

It helped me understand the practical differences between Kafka and RabbitMQ. Sharing it in case it's useful to others in a similar spot. There's also a Claude AI skill included for setup and teardown (/kafka-demo).

Curious what other Kafka demos or learning resources people have found useful.
