Open Source Message Queue (OSMQ)™ is an advanced, pure Java, asynchronous message router, message broker and message middleware framework. OSMQ was designed for high performance, high reliability, and ease of use, with an interface that is less complex than JMS. OSMQ supports a publish-subscribe and point-to-point message architecture, employing a queue-based store-and-forward model of message distribution.
MQue Systems has chosen to release the product as open source, using the GNU public license. To download OSMQ including source code, go to Downloads.
In addition to the GNU public license, MQue Systems also provides commercial licences for its OSMQ and Intebroker products. A commercial non-GPL license covers one server with an unlimited number of connections. The InteBroker/OSMQ license also includes the remote monitor component. To purchase one or more commercial licenses, contact MQue Systems.
InteBroker is MQue Systems's GUI based message broker suite built on top of OSMQ. For a more detailed explanation of InteBroker, including screen shots of the message broker and a copy of the Administrator's Guide, see the InteBroker page.
