Vuze (formerly Azureus) is a Java-based BitTorrent client, with support for I2P and Tor anonymous communication protocols. In 2003, the core developers of Azureus formed a company called Vuze, Inc. (formerly Azureus, Inc.)
The program's logo is the Blue Poison Dart Frog (Dendrobates azureus). The Azureus name was given to the project by co-creator Tyler Pitchford, who uses the Latin names of poison dart frogs as codenames for his development projects.
Azureus was first released in June 2003 at SourceForge.net, mostly to experiment with the Standard Widget Toolkit from Eclipse. It is now one of the most popular BitTorrent clients. Released under the GNU General Public License, Azureus is free software.
