What do people build with it?

USE CASE 1

Send form submissions to Kafka instead of writing directly to a database, so multiple services can process them independently.

USE CASE 2

Build an event-driven backend where services communicate asynchronously through Kafka topics.

USE CASE 3

Decouple parts of a backend so one service doesn't have to wait on another's response.

USE CASE 4

Subscribe to a Kafka topic and trigger custom logic whenever a new message arrives.

What is it built with?
