As you might imagine, there are quite a few BitTorrent clients out there. Some are even good. Among those available include two from Rainberry (formerly BitTorrent, Inc.) the company formed by BitTorrent's developer, Bram Cohen. Rainberry has since been bought out by a cryptocurrency firm, and Cohen is no longer associated with it. We won't be recommending the BitTorrent clients BitTorrent and uTorrent from Rainberry, because both come with advertising, fees, and associated software.With that, let's look at some BitTorrent apps you might want to install.qBittorent: My strongest recommendation is the free and open-source qBittorrent. While its interface is a bit cumbersome, it's been around for a long time, is a clean distribution, works with Macs, Windows, and Linux, and is generally quite powerful. It's not quite as extensible and customizable as other clients, but if you're just getting started, this will get you going.Transmission: Transmission is another free and open-source implementation, this time tuned for MacOS. While there are builds of Transmission for Windows and Linux, this is a gorgeous implementation designed with MacOS users in mind. If you're a Mac user, you probably want to start here.Deluge: Deluge is another free and open-source BitTorrent client. Its claim to fame is that it is very lightweight, meaning it uses very few system resources. You can run this on an old, retired machine and it will do just fine. Deluge also has a pile of extensions and add-ons if you want to customize it.There are lots more, and some commercial applications. But, honestly, I haven't found a commercial application that has enough to offer for its fee, given the considerable capabilities of the three programs spotlighted above.
