Harp intelligently compiles assets as the browser needs them, so it’s insanely fast. All you have to do is Save and Refresh. You can keep your code clean and organized: reuse common elements with partials, and maintain a consistent site design with layouts. Whether you’re making a GitHub project page, or a mobile application using Apache Cordova/PhoneGap, you can easily compile your code to HTML, CSS & JavaScript and host it anywhere.
