Deluge

Deluge is an open source and cross-platform torrent downloader application, a full featured BitTorrent client for GNU/Linux, BSD, Microsoft Windows and Mac OS X operating systems.

It is entirely based on the ​libtorrent library

The application is based on the libtorrent library, which means that it inherits its features. On top of that, the core and graphical user interface are split in order to allow it to run as a daemon in background and enabling you to connect to it remotely.

Includes top-notch BitTorrent functionality

Key components include three different user interfaces, web-based, command-line and GUI written in GTK+, BitTorrent protocol encryption, mainline DHT (Distributed Hash Table), LPD (Local Peer Discovery), µTorrent Peer Exchange and well as support for NAT-PMP and UPnP (Universal Plug and Play).

Among other important features, we can mention support for proxy servers, private torrents, web seed, FAST protocol extension, password protection for torrents, RSS support, configurable bandwidth scheduler, as well as per-torrent and global speed limits.

Under the hood, supported OSes and availability

A quick look under the hood will show us that the application is written entirely in the Python programming language and uses GTK+ for its graphical user interface.

As mentioned, it is a cross-platform application that run on mainstream OSes, including GNU/Linux, BSD, Mac OS X and Microsoft Windows. Supported architectures include 32-bit and 64-bit.

On Linux, you can download it as a universal source archive, but the best way to install it from the official software repositories of your distribution. While the Debian, Ubuntu, Arch Linux, Slackware, Fedora, openSUSE, Gentoo and Foresight distros are officially supported, Deluge is independent of a desktop environment.

A stable, reliable and user-friendly BitTorrent client for Linux

All things considered, Deluge is without no doubt a stable, reliable and user-friendly BitTorrent client for GNU/Linux platforms.

What is new in this release:

• Network Proxy Settings:
• Since libtorrent 0.16 there has only been a single proxy that applies to all types (Peer, web, etc.) so to prevent bugs with accidentally unsetting the proxy values Deluge now only sets a single proxy but mirrors the settings from peer type to the other proxy types for user display only to show that proxy is enabled for all connections. In the GTKUI this means that the other types are greyed out and will be unable to be set. This is a stopgap measure for 1.3 code and is properly fixed for 2.0 release.
• Deluge WebUI:
• Highly recommended to upgrade to this release as it contains a directory traversal security fix that once again has the real potential to compromise your machine.
• Windows OS:
• The dialog button locations will now be uniform across the application. A proper fix to copy the Windows OS button placement will be implemented for 2.x release. See #3012
• There is a confirmed shutdown bug with the standalone client (classic mode) so before shutting down or logging off on Windows, either ensure Deluge is closed or run in thinclient mode. See #3011

What is new in version 1.3.14:
