Self-host swap-in for Amazon SQS. · Self-host Amazon SQS · RabbitMQ on os-alt

RabbitMQ is one of the open-source self-host replacements for Amazon SQS — license MPL-2.0, 10min docker run + management UI to stand up, and $5-15/mo vps for a single broker; clustered for ha adds nodes. Compare against Amazon SQS's $0.40 per 1M requests (Standard); $0.50 per 1M (FIFO); free 1M requests/mo below.

Switching from Amazon SQS to RabbitMQ

Run `docker run -d --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3-management`. Client migration: replace SQS SDK calls (`SendMessage`, `ReceiveMessage`) with AMQP library calls (Pika in Python, amqplib in Node). FIFO semantics map to RabbitMQ single-active-consumer queues; DLQ via the dead-letter-exchange feature. Visibility-timeout maps to RabbitMQ ack semantics + per-message TTL.

Good fit for: 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.
