Gordon Alternatives
Gordon is described as 'An open source Flash runtime written in pure JavaScript' and is an website in the development category. There are three alternatives to Gordon, not only websites but also apps for Adobe Flash Professional, Mac and Windows. The best alternative is Google Swiffy, which is free. Other great sites and apps similar to Gordon are Toolkit for CreateJS and Smokescreen.
Swiffy converts SWF files to HTML5, allowing you to reuse Flash content on devices without a Flash player.
