Key feature breakdown
 |  | |
|---|---|---|
| Architecture | ||
| Single Binary |  Brokers, schema registry, HTTP proxy, Raft consensus all built in |  External dependencies on ZooKeeper/KRaft, JVM, schema registry, and HTTP proxy |
| Unified Platform | Redpanda One (R1) engine allows one cluster to support diverse workloads. Optimize per topic for availability, consistency, latency, safety, networking costs, etc. |  Requires multiple clusters to support different workload types in different deployment scenarios: Kora, WarpStream, Freight, Confluent Platform |
| Cloud Storage Options | Tiered Storage production-proven. Cloud Topics GA early 2026 (BYOC, self-managed) for direct-to-object-storage persistence | Tiered storage support. Diskless options for Freight (serverless) and WarpStream (BYOC), both requiring standalone clusters |
| Enterprise BYOC | Production-proven BYOC. Control plane & data plane are both fully managed and resilient to failure | Immature BYOC offering. WarpStream control plane (Confluent-managed) & data plane (customer-managed) are split and less resistant to failure |
| Performance | Designed for modern hardware; supports high throughput & low latency on less infrastructure and flexible engine configurations | Fewer options to optimize performance; struggles with demanding throughput and latency |
| Ecosystem | ||
| Data Connectors | Redpanda Connect: 300+ data, CDC & AI connectors, simple & composable, config-based & stateless | Kafka Connect: 200+ integrations, no AI, distributed systems complexity, inefficient compute |
| Apache Kafka API | Redpanda natively supports the Kafka API | Confluent natively supports the Kafka API, with some exceptions for WarpStream |
| UI | Redpanda Console is free, lightweight and designed to work across the Kafka ecosystem | More restrictive licensing for Confluent Control Center, with certain features designed only for Confluent Platform customers |
| Apache Flink Integration | Flink compatible, but Flink infrastructure & support are not managed by Redpanda Cloud | Fully managed Flink service available as part of Confluent Cloud |
| Simplified Stream Processing | Simplified stream processing using Redpanda Connect for stateless data transformations, light aggregations, and more | Kafka Connect or Flink adds costs/complexity that is overkill for the majority of streaming ETL use cases |
| Support | ||
| Access Experts 24/7 | Industry-leading support comes included. 24/7/365 coverage for production outages, with access to the experts who write the code | Support sold separately. Tiered support model adds delays that can hinder root cause analysis |
| Cloud Provider Availability | AWS, Google Cloud, Azure, including private connectivity across all 3 (PrivateLink, Private Service Connect, Private Link) | AWS, Google Cloud, Azure, including private connectivity across all 3 (PrivateLink, Private Service Connect, Private Link) |
| Security | Enterprise-grade features like SSO, RBAC, audit-logging & more | Enterprise-grade features like SSO, RBAC, audit-logging & more |
| SLAs | 99.99% for Redpanda Cloud Streaming only (does not include Redpanda Connect) | 99.99% for Confluent Cloud, covers a wider mix of the ecosystem, including Flink & Kafka Connect |
| TCO | Up to 60% cost reduction for fan-in architectures and up to 58% cost reduction for fan-out, according to McKnight benchmark report | Cloud CKU pricing model translates to higher costs; "Component" licenses for Platform drive up cost on top of base enterprise license |
Why Redpanda Streaming?
Redpanda is the high-performance alternative built for the modern era. By replacing the JVM with a C++ engine, we deliver 10x lower tail latencies and 6x lower TCO. No fragmented sidecars, no bolted-on compute silos, and no merger-related distractions. Just one simple, unified platform that stays out of your way so you can build.
Zero Merger Distractions, 100% Innovation
As Confluent integrates into the IBM portfolio, their roadmap is increasingly focused on "billable services" and proprietary lock-in. Redpanda remains an independent, developer-first platform.
True Zero-ETL Lakehouse Integration
Don't waste budget on compute gymnastics. While Confluent uses Flink to reach the lakehouse, Redpanda Iceberg Topics materialize streams into query-ready tables, automatically as part of the broker.
Cost-Effective Solution
Redpanda provides 3-6x greater cost efficiency compared to traditional Kafka infrastructure, lowering both infrastructure and operational costs for your team.
24x7 Expert Support
Enjoy round-the-clock support from dedicated account managers, a direct Slack channel, helpdesk access, and solutions experts always ready to assist.
