About Calypso

Calypso Calypso is a cross platfrom file sharing client using the anonymous network MUTE. Developed using C++ and Qt, Calypso is portable to windows, linux, and other environments. You can try it by following the installation instructions below.

Why Calypso ?

  • Calypso uses the anonymous network MUTE, protecting your privacy.
  • Calypso is multisource, allowing a good download speed.
  • Calypso is fully compatible with MUTE. You can download files shared by MUTE customers and vice versa.
  • Calypso uses "swarming". This means that it loads portions of the file you want in the middle of the file. Thus the hosts who have entrusted a part of the file can send it, and if the original source disappears before someone else has downloaded the entire file, it is still possible to get the complete file.
  • Calypso allows you to start multiple searches. You can then navigate between the different tabs.
  • Calypso has a two level search system. You first start a search for keywords. Then you can filter the results with a regular expression.
