Deluge is a full-featured BitTorrent client for Linux, Unix and Windows. It is written in python, uses libtorrent (rasterbar) at its core and GTK for the main user interface along with web and console interfaces for advanced client/server facility.
Deluge features a rich plugin collection; in fact, most of Deluge’s functionality is available in the form of plugins.
Deluge was created with the intention of being lightweight and unobtrusive. It is our belief that downloading shouldn’t be the primary task on your computer and therefore shouldn’t monopolize system resources.
Deluge will work just fine across many desktop environments such as GNOME, KDE, XFCE and others.
