Deluge is a free software cross-platform BitTorrent client written with Python and GTK+. The program uses the libtorrent-rasterbar C++ library as its backend for torrent networking functionality through the project's own Python bindings.

Alongside the full version, a portable version is offered which does not require installation.[1]


Deluge aims to be a lightweight,[2] secure,[3] and feature-rich[4] client. To help achieve this, most of its features are part of plugin modules which were written by various developers.

Starting with version 1.0, Deluge separated its core from its interface, running it instead in a daemon (server/service), allowing users to remotely manage the application over the web.[5] It has been one of the first clients to support magnet links, introducing this feature with version 1.1.0 released on January 2009.[6]

libtorrent-rasterbar was one of the first BitTorrent software applications to support peer exchange.


Deluge was started by two members of, Zach Tibbitts and Alon Zakai, who previously hosted and maintained the project at Google Code, but have now moved it to its own website.

In its first stages, Deluge was originally titled gTorrent, to reflect that it was targeted for the GNOME desktop environment. When the first version was released on September 25, 2006, it was renamed to Deluge due to an existing project named gtorrent on SourceForge, in addition to the fact that it was finally coded to work not only on GNOME but on any platform which could support GTK+.[7]

The 0.5.x release marked a complete rewrite from the 0.4.x code branch. The 0.5.x branch added support for encryption, peer exchange, binary prefix, and UPnP.

Nearing the time of the 0.5.1 release, the two original developers effectively left the project, leaving Marcos "markybob" Pinto and Andrew "andar" Resch to continue Deluge's development.

Version saw support for both Mac OS X (via MacPorts) and Windows being introduced.

Around this time, Deluge became notable for its resistance to Comcast's bandwidth throttling without a change in code, while clients like Vuze (Azureus) and μTorrent had to borrow the method implemented by Deluge.[8]

From version 1.1.1 through version 1.1.3, Windows installers were temporarily unavailable due to the Windows packager leaving the project.

Following 1.1.3, packages for all operating systems were no longer provided by the developers; instead, source tars and community provided packages were released.
