{{Main|Comparison of BitTorrent clients}}

The BitTorrent specification is free to use and many clients are [[Open-source software|open source]], so BitTorrent clients have been created for all common [[operating systems]] using a variety of [[programming languages]]. The official BitTorrent client, [[μTorrent]], [[qBittorrent]], [[Transmission (BitTorrent client)|Transmission]], [[Vuze]], and [[BitComet]] are some of the most popular clients.<ref>{{cite web|url=https://torrentfreak.com/thunder-blasts-utorrents-market-share-away-091204/|title=Thunder Blasts uTorrent's Market Share Away|last=Van Der Sar|first=Ernesto|date=4 December 2009|publisher=[[TorrentFreak]]|url-status=live|archive-url=https://web.archive.org/web/20091207062921/http://torrentfreak.com/thunder-blasts-utorrents-market-share-away-091204/|archive-date=7 December 2009|access-date=15 September 2011|df=dmy}}</ref><ref>{{cite web|title=uTorrent Dominates BitTorrent Client Market Share|url=https://torrentfreak.com/utorrent-dominates-bittorrent-client-market-share-090624/|publisher=[[TorrentFreak]]|date=24 June 2009|access-date=25 June 2013 | archive-url = https://web.archive.org/web/20140403051947/http://torrentfreak.com/utorrent-dominates-bittorrent-client-market-share-090624/ | archive-date = 3 April 2014| url-status=live}}</ref><ref>{{cite web|title=Windows Public File Sharing Market Share 2015|url=https://www.opswat.com/resources/reports/market-share-usage-analysis-file-sharing-antivirus-june-2015#public-file-sharing|publisher=opswat|access-date=1 April 2016|archive-url=https://web.archive.org/web/20160414045045/https://www.opswat.com/resources/reports/market-share-usage-analysis-file-sharing-antivirus-june-2015#public-file-sharing|archive-date=14 April 2016|url-status=live|df=dmy-all}}</ref><ref>{{cite web|last1=Henry|first1=Alan|title=Most Popular BitTorrent Client 2015|date=19 May 2015 |url=http://lifehacker.com/5813348/five-best-bittorrent-applications/1705622513|publisher=lifehacker|access-date=1 April 2016|archive-url=https://web.archive.org/web/20160409025410/http://lifehacker.com/5813348/five-best-bittorrent-applications/1705622513|archive-date=9 April 2016|url-status=live|df=dmy-all}}</ref>

Some BitTorrent implementations such as [[MLDonkey]] and Torrentflux are designed to run as servers. For example, this can be used to centralize file sharing on a single dedicated server which users share access to on the network.<ref>{{cite web |url=http://www.turnkeylinux.org/torrentserver |title=Torrent Server combines a file server with P2P file sharing |publisher=Turnkeylinux.org |access-date=9 July 2012 |archive-url=https://web.archive.org/web/20120707011646/http://www.turnkeylinux.org/torrentserver |archive-date=7 July 2012 |url-status=live |df=dmy-all }}</ref> Server-oriented BitTorrent implementations can also be hosted by [[Internet hosting service|hosting providers]] at [[colocation centre|co-located]] facilities with high bandwidth Internet connectivity (e.g., a datacenter) which can provide dramatic speed benefits over using BitTorrent from a regular home broadband connection. Services such as [[ImageShack]] can download files on BitTorrent for the user, allowing them to download the entire file by [[HTTP]] once it is finished.

The [[Opera (web browser)|Opera]] [[web browser]] supports BitTorrent natively.<ref>{{cite web| url=https://arstechnica.com/news.ars/post/20070201-8750.html| title=Does network neutrality mean an end to BitTorrent throttling?| first=Nate| last=Anderson| date=1 February 2007| publisher=Ars Technica, LLC| access-date=9 February 2007 | archive-url = https://web.archive.org/web/20081216140732/http://arstechnica.com/news.ars/post/20070201-8750.html | archive-date = 16 December 2008| url-status=live}}</ref> [[Brave (web browser)|Brave]] web browser ships with an [[Browser extension|extension]] which supports [[WebTorrent]], a BitTorrent-like protocol based on [[WebRTC]] instead of [[User Datagram Protocol|UDP]] and [[Transmission Control Protocol|TCP]].<ref>{{cite web| url=https://browserpulse.com/how-to-stream-movies-and-download-torrent-files-in-brave-browser/| title=How to Stream Movies and Download Torrent Files in Brave Browser| author=Mark| date=7 May 2020| publisher=Browser Pulse| access-date=6 October 2020| archive-date=9 October 2020| archive-url=https://web.archive.org/web/20201009082825/https://browserpulse.com/how-to-stream-movies-and-download-torrent-files-in-brave-browser/| url-status=live}}</ref><ref>{{cite web|title=What extensions are built into Brave?|url=https://support.brave.com/hc/en-us/articles/360035025231-What-extensions-are-built-into-Brave-|url-status=live|access-date=January 8, 2022|website=Brave Help Center|archive-date=8 January 2022|archive-url=https://web.archive.org/web/20220108170102/https://support.brave.com/hc/en-us/articles/360035025231-What-extensions-are-built-into-Brave-}}</ref> BitLet allowed users to download Torrents directly from their browser using a [[Java applet]] (until browsers removed support for Java applets).<ref>{{cite web|last=Bahgat|first=Alessandro|date=2008-10-10|title=BitLet - Bittorrent applet|url=https://www.abahgat.com/project/bitlet/|access-date=2022-01-08|website=Alessandro Bahgat|language=en-us|archive-date=21 November 2021|archive-url=https://web.archive.org/web/20211121144706/https://www.abahgat.com/project/bitlet/|url-status=live}}</ref> An increasing number of hardware devices are being made to support BitTorrent. These include routers and NAS devices containing BitTorrent-capable firmware like [[OpenWrt]]. Proprietary versions of the protocol which implement [[Digital rights management|DRM]], encryption, and authentication are found within managed clients such as [[Pando (application)|Pando]].
