RabbitMQ vs Redpanda
Self-host pick — both replace Amazon SQS (Message queue / async messaging).
Both RabbitMQ and Redpanda self-host as a replacement for Amazon SQS (Message queue / async messaging). Pick RabbitMQ if you want the lighter footprint — 10min docker run + management UI, $5-15/mo vps for a single broker; clustered for ha adds nodes. 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
RabbitMQ
Teams who want a battle-tested AMQP broker with rich routing (topic/fanout/headers exchanges) beyond what SQS offers.
Weak at:Operating clustered HA RabbitMQ is non-trivial; budget time for partition/quorum-queue learning.
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.
