TypeBitTorrent client

qBittorrent is a cross-platform free and open-source BitTorrent client.

qBittorrent is written in C++, and thus is a native application. It uses Boost, Qt toolkit (version 4 or 5), and libtorrent-rasterbar library (for the torrent back-end). Its optional search engine is written in Python.


qBittorrent was originally developed in March 2006 by Christophe Dumez,[1] from the Université de technologie de Belfort-Montbéliard (University of Technology of Belfort-Montbeliard) in France.

It is currently developed by contributors worldwide and is funded through donations,[2] led by Sledgehammer999 from Greece, who became project maintainer in June 2013.[10]

  • IP filtering: file types eMule dat, or PeerGuardian
  • Supports IPv6, but cannot use IPv4 and IPv6 at once[11]
  • Integrated RSS feed reader (with advanced download filters) and downloader
  • Integrated torrent search engine (Simultaneous search in many Torrent search sites and Category-specific search requests (e.g. Books, Music, Software))
  • Remote control through Secure Web User Interface

  • Torrent queuing, filtering, and prioritizing

Packages for different Linux distributions are available, though most are provided through official channels via various distributions.[5]


Ghacks suggested qBittorrent as a great alternative to μTorrent, for anybody put off by recent changes made to μTorrent.[14]
