ActiveMQ vs RSMQ: What are the differences?
What is ActiveMQ? A message broker written in Java together with a full JMS client. Apache ActiveMQ is fast, supports many Cross Language Clients and Protocols, comes with easy to use Enterprise Integration Patterns and many advanced features while fully supporting JMS 1.1 and J2EE 1.4. Apache ActiveMQ is released under the Apache 2.0 License.
What is RSMQ? A lightweight message queue for Node.js that requires no dedicated queue server. Just a Redis server. tl;dr: If you run a Redis server and currently use Amazon SQS or a similar message queue you might as well use this fast little replacement. Using a shared Redis server multiple Node.js processes can send / receive messages.
ActiveMQ and RSMQ can be categorized as "Message Queue" tools.
ActiveMQ and RSMQ are both open source tools. ActiveMQ with 1.5K GitHub stars and 1.05K forks on GitHub appears to be more popular than RSMQ with 1.07K GitHub stars and 78 GitHub forks.
