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

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

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,[8] led by Sledgehammer999 from Greece, who became project maintainer in June 2013.[9]

Along with the 4.0.0 release a new logo for the project was unveiled.[10][11]
