Comparison of BitTorrent clients
The following is a general comparison of BitTorrent clients, which are computer programs designed for peer-to-peer file sharing using the BitTorrent protocol.[1]
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 doesn't need a server, the BitTorrent definition of client differs from the conventional meaning expressed in the client–server model.[1]
Bram Cohen, author of the BitTorrent protocol, made the first BitTorrent client, which he also called BitTorrent, and published it in July 2001.[2]
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 2007, five BitTorrent clients were discovered to be Trojan horses that attempt to infect Windows with malware.[3][4][5] Those clients—BitRoll, GetTorrent, Torrent101, µTorrent,[6] and TorrentQ—are excluded from the comparison tables below. In 2013, Thunder Networking Technologies admitted that some of their employees surreptitiously distributed a Trojan horse with certain releases of Xunlei, the company's BitTorrent-ready download manager.[7][8] Xunlei is included in the comparison tables.

BitTorrent client | Cache | Web seeding | Broad-catching (RSS) | Prioritization | Selective downloads | Sequential downloading | SOCKS | Tracker exchange | Remote control via web | Search engine | Auto updates | Reviews and Comments | Notes |
- ↑ 1.0 1.1 1.2 1.3 x86-32 and x86-64builds available.
- ↑ Announcements to the tracker are made via IPv6 if possible, but the client doesn't listen on the respective port.
- ↑ Qdbus interface
- ↑ Automatically configure port forwarding (requires Router with UPnP support)
- ↑ Many 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 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.
- ↑ 7.0 7.1 Tracker included with Linux binaries and with source, but not with Windows binary.
- ↑ 8.0 8.1 Exchanging with BT 6 and µTorrent clients (and now MooPolice).
- ↑ It's UDP based, an experimental feature and only supported by other Azureus based clients.
- ↑ 10.0 10.1 Has its own DHT, a mainline-DHT compatible implementation is available as plugin.
- ↑ µTorrent's DHT implementation is the same as Mainline and BitComet's, but unfortunately this is incompatible with Azureus's implementation.
- ↑ Since Shareaza v2.6.0.0, Shareaza includes Mainline DHT support. Also, Shareaza can use the Gnutella2 network to find other Gnutella2 clients sharing the same torrent. This also includes clients who do not actively seed the torrent in question anymore, as long as file hashes (such as sha1 for example) are known.
- ↑ Since Shareaza v2.5.5.1 r9064.
- ↑ Exchanges with µTorrent and Azureus peers.
- ↑ Since version 2.5.0.2. It's UDP based, an experimental feature and only supported by other Azureus clients.
- ↑ Reduces disk usage, file fragmentation (in case it is not preallocated) and latencies via larger written blocks and cached data for hash checking finished pieces.
- ↑ Recently implemented (unofficial) web seeding feature, see HTTP-Based Seeding Specification
- ↑ Called "preview mode"
- ↑ 19.0 19.1 Provides a Java-based and a simple HTML/JS based WebUI.
- ↑ From version 3.0 this feature is called "Streaming mode". The number of pieces to download sequentially is configurable
- ↑ Opera has a feed aggregator that displays feeds like emails.
- ↑ Since Shareaza v2.4.0.2 r7924.
- ↑ Since Shareaza v2.5.3.1.
- ↑ Shareaza also uses G2 to transmit download metadata, such as BitTorrent trackers to other G2 clients.

Notes
- ↑ Automatically configure port forwarding (requires Router with UPnP support)
- ↑ Many 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 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.
- ↑ Reduces disk usage, file fragmentation (in case it is not preallocated) and latencies due to larger written blocks and cached data for hash checking finished pieces.
- ↑ Recently implemented (unofficial) web seeding feature, see HTTP-Based Seeding Specification
