qBittorrent is a cross-platform free and open-source BitTorrent client written in native C++. It relies on Boost, OpenSSL, zlib, Qt 6 toolkit and the libtorrent-rasterbar library (for the torrent back-end), with an optional search engine written in Python.[5]
qBittorrent was originally developed in March 2006 by Christophe Dumez, from the University of Technology of Belfort-Montbéliard (UTBM).
It is currently developed by contributors worldwide and is funded through donations, led by Sledgehammer999 from Greece, who became project maintainer in June 2013.[6]
Along with the 4.0.0 release a new logo for the project was unveiled.[7] [8]
In February 2023, a security vulnerability affecting versions 4.5.0 and 4.5.1 was discovered in the Web UI running on Windows systems. This vulnerability enabled unauthenticated access to all files on the host computer via a path traversal bug.[9] This issue has been patched in version 4.5.2, which was released to the public on February 23, 2023.[10]
Some of the features present in qBittorrent include:
qBittorrent is cross-platform, available on many operating systems, including: FreeBSD, Linux, macOS, OS/2 (including ArcaOS and eComStation),[11] Windows.
, SourceForge statistics indicate that the most popular qBittorrent version of all supported platforms, 81% of downloads were for Windows computers.[12]
, FossHub statistics indicate qBittorrent as the second most downloaded software with over 75 million downloads.[13]
Packages for different Linux distributions are available, though most are provided through official channels via various distributions.[10]
qBittorrent Enhanced is a fork of qBittorrent intended for blocking leeching clients such as Xunlei. It is hosted on GitHub.
In 2012, Ghacks suggested qBittorrent as a great alternative to μTorrent, for those put off by its controversial adware and bundleware changes.[14]
