RSSOwl is a news aggregator for RSS and Atom News feeds. It is written in Java, and is built on the Eclipse Rich Client Platform which uses SWT as a widget toolkit to allow it to fit in with the look and feel of different operating systems while remaining cross-platform. Released under the Eclipse Public License, RSSOwl is free software.
In addition to its full text searches, saved searches, notifications and filters, RSSOwl v2.1 synchronizes with Google Reader.
