qBittorrent is a free software cross-platform BitTorrent client. The program uses libtorrent-rasterbar library for the torrent back-end (network communication) functionality.

qBittorrent is written in the C++ programming language (utilizing the Boost C++ libraries) and, thus, is a native application. It also uses the Qt framework, version 4 or 5. Its optional search engine is written in the Python programming language; users not willing to install Python can choose not to use the search functionality.

It aims to have a small footprint, to be powerful, to be intuitive, and to be visually attractive, going beyond the current functions widely provided by other applications. qBittorrent is an attempt to provide a μTorrent equivalent that is open-source and multi-platform and in adding a streaming-like function to let users download and play video files.[8] qBittorrent currently offers functionality comparable to other 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. For its BitTorrent and μTP implementation, qBittorrent uses the Rasterbar libtorrent library, which is itself written in C++.


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

It is now developed by contributors from all over the world,[2] led by Sledgehammer999 from Greece, who became the current project maintainer in June 2013.[9]

qBittorrent is cross-platform, available on Linux, Mac OS X, Windows, OS/2, and FreeBSD.

As of September 2012, downloads on SourceForge indicate the Windows version of the application was the most popular of all platforms that qBittorrent supports. SourceForge statistics report that 89% of downloads were for the Windows version of the software.[10]

Packages for different Linux distributions are available, though most are provided through official channels by the distributions themselves.[11]


A review by MakeUseOf described the software as "a very stable and elegant tool" with a clean and clutter-free interface.[12] Ghacks thought qBittorrent was a great alternative to μTorrent.[13]
