uTorrent 3.0 - Free BitTorrent client

What Is uTorrent 3.0?

Micro-Sized Yet Feature Filled

uTorrent 3.0 is a very well-known and appreciated bit torrent client. Most of the features present in other BitTorrent clients are present in uTorrent, including bandwidth prioritization, scheduling, RSS auto-downloading and Mainline DHT (compatible with BitComet). Additionally, uTorrent supports the Protocol Encryption joint specification (compatible with Azureus and above, BitComet 0.63 and above) and peer exchange.

uTorrent 3.0 includes streaming of music and videos, as well as uTorrent Web, a new encrypted WebUI that requires no configuration

As before, this is not feature complete, but many exciting new features have been added to this version: a new, encrypted webUI that doesn't require port forwarding called uTorrent Web; many improvements to the standard WebUI backend; streaming; and a new, optional (non-default) simplified UI.


uTorrent 3.0 was written with efficiency in mind. Unlike many torrent clients, it does not hog valuable system resources - typically using less than 6MB of memory, allowing you to use the computer as if it weren't there at all. Additionally, the program itself is contained within a single executable less than 220 KB in size.

Skinnable and Localized

Various icon, toolbar graphic and status icon replacements are available, and creating your own is very simple. uTorrent also has support for localization, and with a language file present, will automatically switch to your system language. If your language isn't available, you can easily add your own, or edit other existing translations to improve them!

uTorrent is the world's most popular BitTorrent client. In order to make it even better, everal experimental projects have been integrated into the new 3.0 alpha release. The latest version of the main client was supplemented with many new features including remote control and Apps, also the ability to stream video torrents was added.

uTorrent 3.0 Screenshots

uTorrent 3.0 Web (from Project Falcon 2.1) is quite an improvement from the old web client you’ll find in v2.0 and prior. The new web client has really blurred the lines between what’s web and what’s not. Unlike the prior client uTorrent Web supports RSS feeds. Another big change is that it is accessed via https://web.utorrent.com meaning you can manage your client from anywhere on the Internet using a web browser on a PC or an iPhone.

uTorrent 3.0 streaming (also from Falcon) satisfies the impatient by giving the ability to watch content before it is completely downloaded. Streaming is done through your web browser using uTorrent Web and a DivX Web Player and does so decently.

Apps for uTorrent 3.0 (from Project Griffin) is sort of an app store or market, providing web-based add-ons without adding any significant "weight" to the lightweight uTorrent client. This should expand greatly in the next month or so since they just announced a developers challenge which will run until August 13th.
