Best-fit scenarios
Choose Confluent if:
Choose Confluent when you need a fully managed, enterprise-grade Kafka platform with comprehensive governance, 120+ pre-built connectors, Apache Flink stream processing, and proven support for complex hybrid cloud deployments across regulated industries.
Choose Redpanda if:
Choose Redpanda when Kafka API compatibility and its single-binary operating model fit your requirements. Validate performance, operational procedures, and commercial terms with a representative proof of concept.
These scenarios reflect the available product evidence. Your requirements, existing stack, and team expertise should guide the final decision.
Frequently Asked Questions
Can I migrate from Confluent to Redpanda without rewriting my applications?
Yes. Redpanda provides full Kafka API compatibility, so existing Kafka clients, producers, and consumers work without application code changes. You can point your existing Kafka clients at a Redpanda cluster and they will function as expected. However, Confluent-specific features like ksqlDB or Confluent's managed connectors do not have direct equivalents in Redpanda and would need replacement with alternatives like Redpanda Connect or inline data transforms.
How do Confluent and Redpanda compare on performance and latency?
Both products publish architecture and service-level information, but throughput and latency results depend on workload design, configuration, and deployment. Test representative topics, retention settings, consumer patterns, and recovery scenarios before making a platform decision.
Which platform is more cost-effective for high-volume streaming workloads?
Redpanda typically delivers reduced infrastructure costs, claiming up to 6x reduced total costs than equivalent Kafka deployments due to its efficient C++ architecture that reduces hardware requirements by 3x or more. Confluent Cloud uses usage-based pricing starting at $0/month for Basic clusters, but costs can scale significantly with data volume, connectors, and processing add-ons. Redpanda's BYOC model keeps data in your cloud, potentially reducing data transfer costs further.
What happened with IBM's acquisition of Confluent, and does it affect Redpanda?
IBM completed its acquisition of Confluent in March 2026 for approximately $11 billion. Confluent is now part of IBM's Data and AI division, with integrations into watsonx.data, IBM MQ, and IBM Z. For Redpanda, this acquisition has been a tailwind: some organizations concerned about vendor lock-in within IBM's enterprise portfolio have evaluated Redpanda as an independent, Kafka-compatible alternative with a focused streaming mission.
