qBittorrent is a free software cross-platform BitTorrent client GUI written with Qt4. The program uses libtorrent-rasterbar C++ library for the torrent back-end (network communication) functionality. It is developed by Christophe Dumez, from the University of Technology of Belfort-Montbeliard in France. It was started in March 2006 and has been in active development ever since.

qBittorrent is free software that aims to have a small foot-print, to be powerful, intuitive and visually attractive. qBittorrent is an attempt to provide a μTorrent equivalent that is open-source and multi-platform. qBittorrent is currently offering functionality comparable to more popular BitTorrent clients such as Vuze but without requiring the Java Virtual Machine. qBittorrent requires Python only for the search engine while other clients such as Deluge and BitTornado require it for the BitTorrent protocol itself.

Features

The main features present in qBittorrent v2.x are:

• Polished µTorrent-like User Interface
• Well-integrated and extensible search engine
  • Simultaneously search well-known BitTorrent search sites
  • Per-category-specific search requests (e.g. Books, Music, Movies)
• Many Bittorrent extensions: DHT, Peer Exchange, Tracker Exchange, Full encryption, Magnet URI, ...
• Remote control through a Web user interface; Nearly identical to the regular UI, all in Ajax
• Advanced control over trackers, peers, and torrents
  • Torrents queuing and prioritizing
  • Torrent content selection and prioritizing
• UPnP / NAT-PMP port forwarding support
• Available in ~25 languages (Unicode support)
• µTorrent spoofing to bypass private trackers white-listing (Prior to version 2.3.0)
• Advanced RSS support with download filters (inc. regex)
• Bandwidth scheduler
• IP Filtering (eMule and PeerGuardian compatible)
• IPv6 compliant

One of the strength of qBittorrent which distinguishes it from its competitors is its well-integrated search engine which provides an interface similar to the one in eMule, but actually searches on the most popular search Web sites in background.

qBittorrent increased its popularity dramatically in November 2009, when a popular BitTorrent indexing site, thepiratebay.org , switched to magnet URIs, as qBittorrent was then the only BitTorrent client in the Ubuntu repositories with working magnet link support.^{[citation needed]}

qBittorrent is available in about 35 languages thanks to volunteer work of its users throughout the World.

Mac OS X port

As of August 10 2009, qBittorrent is officially available on Mac OS X operating system. The DMG (Apple Disk Image) packages are provided by Stefanos Antaris who joined the project for a university assignment. Although this port of qBittorrent was released recently for this operating system, its developers are hoping users will become interested in this new client.
