Tribler is an open source decentralized BitTorrent client with a feature project allowing anonymous peer-to-peer by default (checkbox permits direct p2p). 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.[3][4] Due to this overlay network, Tribler does not require an external website or indexing service to discover content.[5] The user interface of Tribler is very basic and focused on ease of use instead of diversity of features.[6] Tribler is available for Linux, Windows, and OS X.[7]

Tribler also features a built-in video streamer known as SwarmPlayer.

The name Tribler stems from the word tribe, referring to the usage of social networks in this P2P client. The first version of Tribler was a small enhancement on ABC (Yet Another BitTorrent Client).

In 2009, the development team behind Tribler stated that their efforts for the coming years were focused on the integration of Tribler with television hardware.

In 2014 (with the release of version 6.3.1[8]) Tribler gained a new feature, allowing some anonymity with the introduction of a custom built-in onion routing network.[9] This feature is only for file transfers between Triblers users, not to any clearnet torrent nor to any clearnet BitTorrent client.[10] Because the custom onion network does not use Tor exit nodes, it is enhanced to make every Tribler user to function as a relay.[11]


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.[12] This feature is based on collaborative filtering, also featured on websites such as and 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.[13] 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.

The core software is free and open source software based on the Tribler platform, licensed under the LGPL 2.1.


Tribler was created by university researchers at the Delft University of Technology, who are trying to improve peer-to-peer technology.[14] 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.

The European Union's P2P-Next project to develop an Internet television distribution standard builds on Tribler technology.[15]


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.[16] A warning about Tribler security appeared on the tor-dev mailing list on Dec. 20, 2014[17] and was addressed shortly thereafter via Github.[18]
