Where Transmission is known for staying minimal, qBittorrent on Windows takes the broader route and lists unicode support and many features as part of its pitch. It is a BitTorrent client from The qBittorrent project, and version 5.3.0 is the current build in our catalog. The installer is about 47.7 MB.
Free, open source and no price tag
qBittorrent is free. The license is GPL-3.0, so the source code is open. There are no ads, in-app purchases or paid version to worry about.
The project's own pitch is simple: a good alternative to the other BitTorrent clients.
C++, Qt and the libtorrent engine
The client is programmed in C++ with the Qt toolkit. For the transfer work it uses libtorrent, also called libtorrent-rasterbar, written by Arvid Norberg. The developer describes the program as fast and stable.
It handles torrent and magnet downloads, and it supports unicode. It is listed under P2P clients and download managers.
Version 5.3.0 and the October 2026 update
Version 5.3.0 was released and last updated on October 20, 2026. The Windows package ID is qBittorrent.qBittorrent, which helps if you install through a package manager.
