Transmission is a fast, easy-to-use bittorrent client with support for encryption, a web interface, peer exchange, magnet links, DHT, µTP, UPnP and NAT-PMP port forwarding, webseed support, watch directories, tracker editing, global and per-torrent speed limits, and more.
Transmission has one of the lowest memory & resource footprints of any major BitTorrent client. Transmission's light overhead is one reason why it is so well suited for home NAS and media servers. Having been used by Western Digital, Zyxel and Belkin, Transmission gives truly impressive performance on almost any compatible hardware.
Transmission is an open source, volunteer-based project. Unlike some BitTorrent clients, Transmission doesn't play games with its users to make money.
- Transmission doesn't bundle toolbars, pop-up ads, flash ads, twitter tools, or anything else.
- It doesn't hold some features back for a payware version.
- Its source code is available for anyone to review.
- Transmission doesn't track users, the website and forums have no third-party ads or analytics.
