Tribler is an open source anonymous peer-to-peer decentralized Bit Torrent client. Tribler is based on the Bit Torrent protocol and uses an overlay network for content searching, which makes the program operate independent of external websites and renders it immune to limiting external action, for example, government restraint. Due to this overlay network Tribler does not require an external website or indexing service to discover content. The user interface of Tribler is very basic and focused on ease of use, instead of diversity of features. Tribler is available for Linux, Windows, and OS X.
