Many BitTorrent programs are open-source software others are freeware, adware or shareware. īram Cohen, author of the BitTorrent protocol, made the first BitTorrent client, which he also called BitTorrent, and published it in July 2001. Because BitTorrent is a peer-to-peer communications protocol that does not need a server, the BitTorrent definition of client differs from the conventional meaning expressed in the client–server model.

A BitTorrent client enables a user to exchange data as a peer in one or more swarms. The BitTorrent protocol coordinates segmented file transfer among peers connected in a swarm. The following is a general comparison of BitTorrent clients, which are computer programs designed for peer-to-peer file sharing using the BitTorrent protocol.

For the software application by Bram Cohen, see BitTorrent (software).
