An interactive playground for learning Apache Kafka: a real 3-broker cluster with services in C#, Go and Python. Break it and watch what happens.
- 🗺 Live map — messages flowing through brokers, partitions and consumer groups in real time.
- 💥 Failures — kill brokers, cut the network, build up lag; every event has a "why?".
- 🎓 Learning — guided scenarios, cheat sheets and flashcards.
