Apache ActiveMQ vs TIBCO Enterprise Message Service

Apache ActiveMQ is an open-source messaging and Integration Patterns server for applications that exchange messages. It is self-hosted and supports OpenWire, STOMP, AMQP 1.0, MQTT 3.1, and REST. Listed client languages include Java, C, C++, C#, Ruby, Perl, Python, and PHP. Messaging features include message groups, virtual and composite destinations, wildcards, and enterprise integration patterns. ActiveMQ fully supports JMS 1.1 and J2EE 1.4+ messaging, including transient, persistent, transactional, and XA modes; support for Jakarta Messaging 3.1 and JMS 2.0 is partial. Transport options include in-VM, TCP, SSL, NIO, UDP, multicast, JGroups, and JXTA, with JDBC persistence and a high-performance journal. Browser access is available through a REST API and Ajax web streaming. Security options include pluggable providers, JAAS authentication, XML-configured authorization, and user, group, and destination permissions. ActiveMQ Classic costs nothing under the Apache License 2.0.
