ActiveMQ vs Kestrel: 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 Kestrel? Simple, distributed message queue system. Kestrel is based on Blaine Cook's "starling" simple, distributed message queue, with added features and bulletproofing, as well as the scalability offered by actors and the JVM.
ActiveMQ and Kestrel can be categorized as "Message Queue" tools.
ActiveMQ and Kestrel are both open source tools. Kestrel with 2.8K GitHub stars and 326 forks on GitHub appears to be more popular than ActiveMQ with 1.5K GitHub stars and 1.05K GitHub forks.
