Our Verdict

Apache Kafka is the proven standard with the largest ecosystem — choose it if you have a dedicated platform team. Confluent removes Kafka's operational burden with managed infrastructure, 120+ connectors, and Schema Registry — choose it if you want Kafka without the ops pain. Redpanda is the modern challenger with lower latency, simpler operations, and no JVM — choose it for latency-sensitive workloads or if you find Kafka operationally painful.

💡 This verdict is based on general use cases. Your specific requirements, existing tech stack, and team expertise should guide your final decision.

Frequently Asked Questions

Is Redpanda really compatible with Kafka?

Yes, Redpanda implements the Kafka API protocol, so existing Kafka clients, Kafka Connect connectors, and Kafka Streams applications work without code changes. Compatibility is 99%+ for standard use cases.

Why is Redpanda faster than Kafka?

Redpanda is written in C++ using the Seastar framework with a thread-per-core architecture. This eliminates JVM garbage collection pauses, reduces context switching, and provides predictable low latency (2-10ms p99 vs Kafka's 10-50ms).

How much does Confluent Cloud cost?

Confluent Cloud starts at $0.004/partition-hour for basic clusters, with the first $400/month free. A typical production deployment costs $800–$5,000/month depending on throughput and features. Dedicated clusters start at ~$2,200/month.

Should I use Kafka or Confluent?

If you have a platform team with Kafka expertise and want maximum control, self-managed Kafka saves money. If you want managed infrastructure, connectors, Schema Registry, and stream processing without operational burden, Confluent is worth the premium.

Is Apache Kafka free?

Yes, Apache Kafka is free and open-source under the Apache 2.0 license. You only pay for the infrastructure to run it. A production cluster typically costs $1,000–$5,000/month in cloud infrastructure.
