kodeWeave

kodeWeave is a realtime HTML5/CSS3/JS playground that allows you to export your web applications as a desktop or chrome application, while also incorporating libraries like jquery, mootools, mondernizer, bootstrap, etc: all by checking a box. kodeWeave is similar to jsfiddle, jsbin, liveweave, codepen, and tinkerbin, but allows you to export for desktops and chromebooks. Which also has an ui designed for tablets and phones. kodeWeave's source code is also available on Github - https://github.com/michaelsboost/kodeWeave
