Deluge is a fully-featured cross-platform BitTorrent client. It is Free Software, licensed under the GNU GPLv3+ and adheres to freedesktop standards enabling it to work across many desktop environments.  Deluge contains the common features to BitTorrent clients such as Protocol Encryption, DHT, Local Peer Discovery (LSD), Peer Exchange (PEX), UPnP, NAT-PMP, Proxy support, Web seeds, global and per-torrent speed limits. As Deluge heavily utilises the libtorrent library it has a comprehensive list of the features provided. Deluge has been designed to run as both a normal standalone desktop application and as a client-server. In Thinclient mode a Deluge daemon handles all the BitTorrent activity and is able to run on headless machines with the user-interfaces connecting remotely from any other platform.
