Apache Kafka Confluent Redpanda Apache Pulsar
Vendor Apache Software Foundation Confluent, Inc. Redpanda Data, Inc. Apache Software Foundation
Pricing model Open source + paid options Usage-based Usage-based Open source + paid options
Free tier Yes Yes Yes Yes
Deployment Self-hosted Cloud, Self-hosted Cloud, Self-hosted Self-hosted
Open source Yes (Apache-2.0) No No (BSL-1.1) Yes (Apache-2.0)
Best for Engineering teams building event-driven architectures who want full control over a self-managed streaming backbone. Teams wanting managed Kafka with enterprise features without operating brokers themselves. Teams wanting Kafka-compatible streaming with lower operational overhead or latency than JVM-based Kafka. Teams needing native multi-tenancy or geo-replication in a self-hosted streaming platform.
Pricing

Free and open source with no vendor pricing; operating costs depend entirely on self-hosted infrastructure or a chosen managed distribution.
