Overview
qBittorrent is a free, open-source BitTorrent client originally created in March 2006 by Christophe Dumez, a French PhD student, as a lightweight, ad-free alternative to increasingly feature-bloated commercial clients. Leadership passed to contributor sledgehammer999 in 2013, who has led its development since.
Written in native C++ with the Qt 6 toolkit and the libtorrent-rasterbar library, qBittorrent is distributed under GPLv3+ with an OpenSSL linking exception, and it remains entirely free with no advertising or paid tiers.
Key Features
The client includes an integrated torrent search engine via Python search plugins, automated RSS feed monitoring and downloading, sequential downloading for approximate media streaming, and bandwidth scheduling and IP filtering controls.
A secure, browser-accessible web UI allows full remote management of downloads, making qBittorrent popular for headless server, NAS, and Docker-based torrenting setups in addition to standard desktop use.
Pricing
qBittorrent is completely free and open source under the GPLv3+ license with an OpenSSL exception; there are no paid editions, subscriptions, or license fees.
Unlike some competing torrent clients, qBittorrent does not bundle advertising, sponsored offers, or paid upgrade prompts of any kind.
