The Lens

Redpanda is a Kafka-compatible streaming platform that eliminates the operational complexity that scares teams away from Kafka. Kafka-compatible API, 10x faster, and no Java Virtual Machine or ZooKeeper to manage.

Written in C++ with a thread-per-core architecture. Single binary deployment. Your existing Kafka clients, connectors, and tooling work unchanged, just point them at Redpanda instead. Backed by a well-funded company ($100M+ raised). This is production-grade infrastructure, not a side project.

Self-hosted Community edition is free. It's usable: no artificial limits on throughput or partitions. Enterprise adds features like continuous data balancing, tiered storage to S3, Kerberos auth, and audit logging.

The catch: the license (BSL-1.1) means you can't offer Redpanda as a competing managed streaming service. For internal use, no problem. Enterprise pricing isn't published but expect it to be significant: this is infrastructure software for companies with real streaming needs. Also, while Kafka compatibility is excellent, some niche Kafka Streams features and Connect plugins may need testing.

### What's Free

**Community Edition (self-hosted):** Full Kafka API compatibility, single binary deployment, no JVM, no ZooKeeper, rack awareness, schema registry, HTTP proxy (Pandaproxy), admin API. No throughput or partition limits.

### What's Behind the Paywall

**Enterprise (self-hosted, custom pricing):** - Continuous data balancing - Tiered storage (offload cold data to S3) - Kerberos and OIDC authentication - Audit logging - Remote read replicas - 24/7 support

**Redpanda Cloud (managed):** - **Serverless:** Pay-per-use, starts at ~$0.08/million messages. Good for dev/testing. - **Dedicated:** Starts around $600/mo for a basic cluster. Production workloads. - **BYOC (Bring Your Own Cloud):** Runs in your AWS/GCP account. Enterprise pricing.

### The Math

Kafka on AWS (MSK): $150-500/mo for a basic cluster + significant ops overhead. Redpanda self-hosted: $0 software + VPS costs ($50-200/mo for a basic cluster). Redpanda Cloud: $600+/mo managed. Self-hosting saves the most if you have the ops team.

### Verdict

Community edition is production-ready for most use cases. Pay for Enterprise when you need tiered storage or compliance features. Cloud when you need managed ops.
