Since about 2001, the website DemoChoice.org has been providing a voter interface system for running elections with instant runoff voting and the single transferable vote. Separately, OpenSTV has been providing a desktop application and vote-counting engine since 2003.

The developers of DemoChoice and OpenSTV have come together to create a joint effort that incorporates the best of both projects. DemoChoice now has a version that uses OpenSTV's vote counting engine at http://openstv.demochoice.org/.

This version of DemoChoice supports most of OpenSTV's counting methods, and allows you to run a complete election, from collecting the votes to displaying the election results.
