Kinesis is open-source
Kafka is proprietary
What is the difference between Apache Kafka and Amazon Kinesis?
Kafka is managed; Kinesis is open-source
Kafka is open-source; Kinesis is managed
No difference
Both are managed services

Using Kafka Streams API
Automatically in brokers
Only in producers
Not supported
