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.[8][9]

History

QBittorent Mascot

qBittorrent was originally developed in March 2006 by Christophe Dumez,[1] from the University of Technology of Belfort-Montbéliard (UTBM).

It is currently developed by contributors worldwide and is funded through donations,[10] led by Sledgehammer999 from Greece, who became project maintainer in June 2013.[11]

Along with the 4.0.0 release a new logo for the project was unveiled.[12][13]

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.[14] This issue has been patched in version 4.5.2, which was released to the public on February 23, 2023.[15]

Features

Some of the features present in qBittorrent include:

  • Bandwidth scheduler
  • Bind all traffic to a specific interface
  • Control over torrents, trackers and peers (torrents queueing and prioritizing and torrent content selection and prioritizing)
  • DHT, PEX, encrypted connections, LPD, UPnP, NAT-PMP port forwarding support, µTP, magnet links, private torrents, v4.6.0 added (experimental) I2P support[15]
  • IP filtering: file types eMule dat or PeerGuardian
  • IPv6 support
  • Integrated RSS feed reader (with advanced download filters) and downloader
  • Integrated torrent search engine (simultaneous search in many torrent search sites and category-specific search requests, such as books, music and software)
  • Remote control through a secure web user interface
  • Sequential downloading (download in order). Enables "streaming" media files
  • Super-seeding option
  • Torrent creation tool
  • Torrent queuing, filtering and prioritizing
  • Unicode support, available in ≈70 languages[6]

Versions

qBittorrent is cross-platform, available on many operating systems, including: FreeBSD, Linux, macOS, OS/2 (including ArcaOS and eComStation),[16] Windows.

(As of July 2017), SourceForge statistics indicate that the most popular qBittorrent version of all supported platforms, 81% of downloads were for Windows computers.[17]

(As of May 2020), FossHub statistics indicate qBittorrent as the second most downloaded software with over 75 million downloads.[18]

Packages for different Linux distributions are available, though most are provided through official channels via various distributions.[15]

qBittorrent Enhanced is a fork of qBittorrent intended for blocking leeching clients such as Xunlei. It is hosted on GitHub.[citation needed]

Reception

In 2012, Ghacks suggested qBittorrent as a great alternative to μTorrent, for those put off by its controversial adware and bundleware changes.[19]
