comparison of BitTorrent clients

{{short description|None}}

The following is a general comparison of BitTorrent clients, which are computer programs designed for peer-to-peer file sharing using the BitTorrent protocol.{{cite book |author= |title=BitTorrent User Manual |chapter=Glossary |chapter-url=http://www.bittorrent.com/help/manual/glossary#client |access-date=2 July 2013 |publisher=BitTorrent, Inc. |location=San Francisco |archive-date=28 June 2013 |archive-url=https://web.archive.org/web/20130628015036/http://www.bittorrent.com/help/manual/glossary#client |url-status=live }}

The BitTorrent protocol coordinates segmented file transfer among peers connected in a swarm. A BitTorrent client enables a user to exchange data as a peer in one or more swarms. 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.

Bram Cohen, author of the BitTorrent protocol, made the first BitTorrent client, which he also called BitTorrent, and published it in July 2001.{{cite web |last=Cohen |first=Bram |url=http://finance.groups.yahoo.com/group/decentralization/message/3160 |title=BitTorrent – a new P2P app |website=Decentralization · Implications of the end-to-end principle |publisher=Yahoo! Groups |date=2 July 2001 |access-date=2 July 2013 |archive-date=29 January 2008 |archive-url=https://web.archive.org/web/20080129085545/http://finance.groups.yahoo.com/group/decentralization/message/3160 |url-status=dead }}

Many BitTorrent programs are open-source software; others are freeware, adware or shareware. Some download managers, such as FlashGet and GetRight, are BitTorrent-ready. Opera 12, a web browser, can also transfer files via BitTorrent.

In 2013 Thunder Networking Technologies publicly revealed that some of their employees surreptitiously distributed a Trojan horse with certain releases of Xunlei, the company's BitTorrent-ready download manager.{{cite web |url=http://torrentfreak.com/google-backed-file-sharing-spreads-malware-131014/ |title=Google-backed BitTorrent client spread malware to Windows PCs and Android devices |last=Van Der Sar |first=Ernesto |date=14 October 2013 |website=TorrentFreak |access-date=19 November 2013 |archive-date=18 December 2013 |archive-url=https://web.archive.org/web/20131218142524/http://torrentfreak.com/google-backed-file-sharing-spreads-malware-131014/ |url-status=live }}{{cite web |url=https://www.theguardian.com/technology/2013/oct/15/google-bittorrent-malware-windows-android-xunlei-china |title=Google-Backed File-Sharing Service Spreads Malware |last=Gibbs |first=Samuel |date=15 October 2013 |website=The Guardian |publisher=Guardian News and Media |access-date=19 November 2013 |archive-date=18 November 2013 |archive-url=https://web.archive.org/web/20131118213046/http://www.theguardian.com/technology/2013/oct/15/google-bittorrent-malware-windows-android-xunlei-china |url-status=live }} Xunlei is included in the comparison tables.

! NAT traversalMany clients claim to support this, but just UPnP calls for opening a TCP port is not effective and disabled by factory default in most new hardware. "UDP NAT Traversal" is the proper working solution, supported by just a few.

! DHT protocolDHT permits use of trackerless torrents (with supporting clients) to resume normal torrents when their tracker is down. However, some trackers that register their users for keeping tabs on fair usage (such as a ratio of bytes downloaded to uploaded) may not reliably measure and update usage for users employing DHT.

However, some trackers that register their users for keeping tabs on fair usage (such as a ratio of bytes downloaded to uploaded) may not reliably measure and update usage for users employing DHT.}}
