partnered to write a Torrent Genie to let people who ran Vuze and owned a Belkin router keep sharing files even when Vuze wasn't running, they decided to use Transmission - not Vuze's own BitTorrent client - on the router. Transmission's small footprint is one reason why many home device manufacturers, such as Imageshack chose Transmission for its BitTorrent farms because the competition requires amounts of memory several times greater than Transmission. Transmission also has the lowest memory footprint of any major BitTorrent client. It even used less CPU than some non-GUI clients. In separate benchmarks, Linux Format and Lacrocivious both found Transmission to use less CPU than any other GUI client. When Ubuntu chose Transmission as its default BitTorrent client, one of the most-cited reasons was its easy learning curve. 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. Transmission is designed for easy, powerful use. We don't track our users, and our website and forums have no third-party ads or analytics.

Its source code is available for anyone to review.

It doesn't hold some features back for a payware version.

Unlike some BitTorrent clients, Transmission doesn't play games with its users to make money:

Transmission is an open source, volunteer-based project. Transmission is a cross-platform BitTorrent client that is: Open Source.
