Why people consider alternatives to Apache Kafka

Kafka moves data at massive scale. When millions of events per second need to flow between systems reliably, Kafka provides the highway.

Teams most often switch away when one of these starts to bite:

Pricing at scale as usage or premium tiers add up.
Missing integrations with the rest of your stack.
Performance or scale limits as your needs grow.
A specific feature gap you have hit in etl & data pipelines.

The 2 direct alternatives below cover the same core job (ETL & data pipelines) with different trade-offs. The 6 tools marked "Same category as Apache Kafka" fit the category but replace Apache Kafka less directly.
