Tribler is an open source anonymous peer-to-peer decentralized BitTorrent client. Tribler is based on the BitTorrent 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.
Tribler also features a built-in video streamer known as SwarmPlayer.
In 2009, the development team behind Tribler stated that their efforts for the coming years were focused on integration of Tribler in television hardware.
Tribler adds keyword search ability to the BitTorrent file download protocol using a gossip protocol, somewhat similar to the eXeem network which was shut down in 2005. The software includes the ability to recommend content. After a dozen downloads the Tribler software can roughly estimate the download taste of the user and recommends content. This feature is based on collaborative filtering, also featured on websites such as Last.fm and Amazon.com. Another feature of Tribler is a limited form of social networking and donation of upload capacity. Tribler includes the ability to mark specific users as online friends. Such friends can be used to increase the download speed of files by using their upload capacity. Due to these features Tribler differs from other popular BitTorrent clients such as Vuze and μTorrent.
The SwarmPlayer is a Python-based BitTorrent Internet TV viewer. It allows one to watch BitTorrent-hosted peer-to-peer digital media distribution of video on demand and plays live Tribler streaming media. It is based on the same core as the Tribler TV application.
Tribler was created by university researchers at the Delft University of Technology, who are trying to improve peer-to-peer technology. Tribler is designed to enhance BitTorrent by removing the need for central elements such as the websites for finding content, as well as being anonymous.
After a news article on TorrentFreak in February 2012 mentioned Tribler's decentralization and the fact that its index is impossible to take down, the website became hugely popular, causing it to be reduced to just the download page to satisfy demand. A warning about Tribler security appeared on the torproject.org website on Dec. 20, 2014 and was addressed shortly thereafter via Github.
