Transmission is a cross-platform BitTorrent client that is:
Free and Community-Driven.
Transmission differs from bigger clients like μTorrent, Vuze, and BitComet in that it is volunteer-based, open source, and noncommercial. There is no payware version as with Vuze Plus. We don't bundle toolbars, adware, DNA, or anything else. If we did, someone else would fork the project and strip it back out. So what you see is what you get -- and if you'd like to check under the hood to see for yourself, the source code is available for anyone to read.
If you're a programmer, translator, tester, web designer, graphic artist, or a regular person who wants to help, we happily welcome volunteers.
Easy.
Transmission is designed to for easy, powerful use. We've set the defaults to "Just Work" and it only takes a few clicks to configure advanced features like watch directories, bad peer blocklists, and the web interface. When Ubuntu chose Transmission as its default BitTorrent client, one of the most-cited reasons was its easy learning curve.
Lean.
Transmission has the lowest memory footprint of any major BitTorrent client. Imageshack chose Transmission for its BitTorrent farms because the competition "requires amounts of memory several times greater than Transmission". The headless version of Transmission is the client of choice on low-memory hardware, leading many users to install it on their routers to leave running 24/7. Some commercial devices ship with it preinstalled.
Native.
Unlike many cross-platform applications, Transmission integrates seamlessly with your operating system.
The Mac OS X interface is written in Objective-C and uses Growl notifications and dock badging to keep you informed.
"It's fast, it's extremely lightweight, and — even though it's available for a variety of platforms — it behaves just as you'd expect a Mac program to."
Macworld, naming Transmission a "Mac Gem"
The GTK+ interface has been carefully written to follow the GNOME Human Interface Guidelines. If your desktop supports popup notifications, desktop sounds, and a system tray, the GTK+ interface will make use of them.
Powerful.
Transmission has the features you want from a BitTorrent client: encryption, a web interface, peer exchange, magnet links, DHT, UPnP and NAT-PMP port forwarding, webseed support, watch directories, tracker editing, global and per-torrent speed limits, and more.
