NATS JetStream vs Redpanda
Self-host pick — both replace Amazon SQS (Message queue / async messaging).
Both NATS JetStream and Redpanda self-host as a replacement for Amazon SQS (Message queue / async messaging). Pick NATS JetStream if you want the lighter footprint — 5min single-binary or docker run, $5-10/mo vps — go binary is light; clustering is straightforward. Pick Redpanda if you need streaming-shaped workloads where you want Kafka semantics (replay, retention) without operating ZooKeeper or a JVM cluster — 20min docker-compose (Redpanda + Console UI) and $15-40/mo vps — single-binary kafka-compatible broker, no jvm.

Good fit for
NATS JetStream
Microservice meshes that want pub/sub + queue + key-value + object store from one binary, with sub-millisecond latency.
Weak at:Less mature observability ecosystem than RabbitMQ; some advanced patterns require deeper NATS-specific knowledge.
Redpanda
Streaming-shaped workloads where you want Kafka semantics (replay, retention) without operating ZooKeeper or a JVM cluster.
Weak at:BSL license restricts commercial managed-service redistribution; cluster ops still needs Kafka mental model.
