It aims to have a small foot-print, to be powerful, intuitive and visually attractive going beyond the current functions widely provided by other applications. qBittorrent is an attempt to provide a μTorrent (or "uTorrent") equivalent that is open-source and multi-platform adding a streaming-like function to let users download-and-play video files. 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++.
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.
Packages for different Linux distributions are available, though most are provided through official channels by the distributions themselves.
