Dijjer is free P2P software that dramatically reduces the bandwidth needed to host large files.

Bandwidth is a problem for anyone hosting big files. As soon as your music, mp3 blog, or movie gets too popular, either your site goes down or you get hit with a huge bandwidth bill. Worse, the cost and hassle of distributing large media files means that the internet isn't living up to its potential as a democratic medium. Dijjer solves this problem. What distinguishes it from similar P2P tools (like Bittorrent) is how easy it is to use for publishers and users.

Using Dijjer on Your Website is So Simple

You don't need to install anything. Just put a file on your site as you normally do, but add "http://www.dijjer.org/get/" to the beginning of your links:

When they click a Dijjer link, users will get some of the file from your website, but most of it will come from other people running Dijjer. That's how you save bandwidth. And when someone clicks on the link who hasn't used Dijjer before, they'll get help installing it. After that, downloads happen seamlessly inside their web browser. Try it!

The Dijjer Difference

Downloads happen in your browser. Most p2p clients make you use a separate program. Dijjer doesn't.

Play media files as they download. If you're downloading a song or a movie, you can listen / watch it as it's downloading-- try it!

Works great with RSS & podcasting. Dijjer will work perfectly with ipodder, ipodderx, radio, and every other podcasting "aggregator". More info.

Works for Windows, Mac, and Linux. Everybody can run Dijjer.

No spyware. No adware. No secrets. The Dijjer source code is free, open source, and available to everyone (why this matters).

Copyright friendly. Dijjer only downloads files that are on websites. So for copyright holders, policing Dijjer is exactly the same as policing websites. More info.
