Fuse Mediation Router is a certified distribution of Apache Camel produced by FuseSource. FuseSource does all of its development and bug fixes as part of the Apache Camel community, so there are no functional differences between the two. FuseSource may do more frequent releases than Apache, so it is possible to get bug fixes from a Fuse Mediation Router release sooner than from an official Apache Camel release.
In addition to providing a well tested version of Apache Camel, FuseSource also offers an Eclipse based IDE-Fuse IDE for Camel - (currently beta) -for editing XML DSL routes.
