A BitTorrent client is a computer program that handles downloading and uploading files using the BitTorrents protocol.
I saw my friends using a variety of BitTorrent clients in the early 2000s, but the first one I used was Shareaza since I already had it installed for peer-to-peer file sharing. Finding it quite lacking, I switched to μTorrent which I used for years. However, as that program kept removing features and adding ads, I eventually replaced it with QBittorrent, which is what I use now.
|QBittorrent||BSD, Linux, Macintosh, Windows||Favorite. Good replacement for μTorrent.|
|μTorrent||Android, Linux, Macintosh, Windows||Adware.|
|Shareaza||Windows||BitTorrent was tacked on.|
|Vuze||Android, Linux, Macintosh, Windows||Severely bloated.|
