ElasticMQ is a lightweight, fully asynchronous, in-memory message queue implementation written in Scala / Akka. It provides a feature-compatible Amazon SQS REST API interface for testing, local development, or embedded usage. It can persist queues or run purely in-memory and also supports Docker deployment and a web UI.

Features

  • SQS-compatible HTTP REST API for full integration testing
  • Runs stand-alone, embedded in JVM, or via Docker container
  • Optionally persistent queues via file or SQL backends
  • Fully asynchronous Akka actor-based architecture
  • Web UI for viewing queues, messages, and operations
  • Supports message batching, visibility timeout, and delay queues
