Deluge is a new open source cross platform BitTorrent client which sports the kind of nice clean user interface that you can take home to your mother. It’s not particularly lean, but it supports plugins for extra functionality and the fact it works on Mac, Linux and Windows is a definite plus. The install is a breeze and in use it’s easy to navigate and fast, which makes it a worthy contender. Definitely worth a look.
Deluge is a full-featured BitTorrent client for Linux, Unix and Windows. It uses libtorrent in it’s backend and PyGTK for it’s user interface. 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.
Any idea how this performs in comparison to Azureus?
I'm not sure, I've never been an Azureus fan actually. :-)
