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, so systems without a Python implementation installed cannot use that.


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.[9]
