BitComet (originally named SimpleBT client from versions 0.11 to 0.37) is a cross-protocol , HTTP and FTP client written in C++ for Microsoft Windows and available in 52 different languages. Its first public release was version 0.28. The current BitComet logo has been used since version 0.50.

The BitComet program is a multi-threaded multi-protocol hybrid download manager and Peer-to-peer (P2P) file-sharing application. It supports simultaneous download tasks. To complete a particular download, it can draw parts of files from many sources across different P2P and client–server protocols.

BitComet's chief features include an embedded Internet Explorer window to let users search for torrents. Along with the features typical of contemporary BitTorrent clients, it supports UPnP gateway configuration, bandwidth scheduling, , selecting only certain files for download inside a torrent package, NAT traversal (removed in v.1.03),Peer Exchange (in older versions, using a proprietary protocol and starting with v.1.19 also by using the Extension Protocol, implementing a PEX mechanism compatible with µTorrent / Mainline PEX), Initial-Seeding (Super-Seeding) and support for Magnet Links.

When downloading, BitComet gives you the option to prioritize the first and last portions of media files so that files may be previewed before they are completely downloaded.
It also has a "Preview Download Mode" in which all pieces of the torrent will be, basically, downloaded sequentially thus allowing the user to play a media file while downloading (provided that the downloading speed and piece availability stay ahead of playing bitrate).
BitComet also allows users to share their .torrent files, on a searchable P2P network, with other BitComet users through the torrent sharing feature, named "Torrent Share" in previous versions and renamed to "Torrent Exchange" since v.1.17. BitComet uses the Kademlia (mainline) DHT to operate even when the tracker is offline. BitComet is capable of downloading files over HTTP and FTP as well as bittorrent, and it includes download plugins for Firefox, Internet Explorer, and Maxthon.
