Transmission, The Lightweight BitTorrent Client

Wez Pyke 04-07-2008

Transmission-Logo Transmission is a free and open source bit torrent client that runs natively on multiple operating systems and is available in many languages worldwide. Transmission is very lightweight and probably one of the best bit torrent clients around. Transmission was first released on September 15th 2005 and has came quite a long way since its first release.


If you use Ubuntu then you will most likely know of Transmission because it is the default bit torrent client.

A really great thing about Transmission is that it has been ported to the iPhone – this makes it possible for you to download torrents with your iPhone while on the move. Although it may drain your iPhone battery, it can still come in pretty useful.

The main build for Transmission though is for Mac OS X and includes specific features that no other build on another operating system has.

Some of the features that are specific to Mac OS X are downloading and seeding queues, basic scheduling, auto-seeding options, groups, customizable toolbar and an advanced progress box. For notifications there is support for the dock and Growl and to keep you updated. Transmission uses Sparkle to check for the latest program versions for you to download.

Transmission Features



Transmission allows for files to be dropped onto the application. Once you open the file you can then select what files you want to download that are inside the torrent, trash the torrent file, give the torrent file a group color and verify the local data so that the transfer starts from where it left off if you have attempted to download that torrent before.

You can easily view torrents that are active, downloading, seedings or paused by clicking the tabs near the top of Transmission and if you have a lot of files within Transmission then you can also narrow it down even more by using the search.

In the inspector you can get general information such as what bit torrent application was used to create the torrent as well as the date that it was created, information on the tracker, the hash, the percentage that the file is complete as well as a ratio of your download and upload on a file, people that you are downloading the torrent from and the files that you have selected to download.


Like most bit torrent applications Transmission will also allow you to create your own torrents in no time simply by choosing the file you want to create as a torrent and the tracker URL as well as comments then hit create and you’re all done.

If you’re downloading or uploading other files then you can limit the speed in which Transmission downloads and uploads torrents.

    I absolutely love Transmission. I use OS X and that's my bittorrent client of choice. I've used it for about a year and it has been updated fairly regularly with great features and awesome UI.

    It's only the default in Ubuntu 8.04 (Hardy Heron). Previously, the default was awful, so if you're going "what? Ubuntu's default torrent app sucks!" that's because you've only seen that gnome-btdownload one that was in the old versions. Transmission is definitely nice for a simple torrent client, but I still prefer Deluge
