Xyzzy is a simple website framework built for the rapid construction of static websites and design prototypes. It is a simple website template that seeks to standardize the implementation of various development patterns and resources in an attempt to shorten production time, improve code readability, and increase cross-browser support.
Technically, Xyzzy is a template website. It packages common web development resources into an easily customizable HTML+CSS presentation layer. There is no administration panel, no documentation, and no WYSIWYG text editor. To use Xyzzy, simply drop the framework files in your docroot. From there you can edit the code by hand in some no-frills text editor, breaking free of your fancy IDE training wheels to become the badass coder you've always wanted to be.
Philosophically, Xyzzy is a rebel. Xyzzy doesn't want to be the type of framework that you can use out of the box to build most websites, and it will make your life harder if you try to use it as such. Instead, Xyzzy maintains a subtle but complex mixture of utilitarian functionality + instruction by example. It should work as a basic foundation that helps inspire you to select and implement more effective solutions to finish the product, rather than forcing you to select from a rigid menu of programming magic just for the sake of being comprehensive.
The Xyzzy framework was created by Mighty Media in an effort to standardize their production of functional website prototypes. This corageous agency creates superb designs that often cannot effectively be represented to clients through graphic mockups, so their projects typically move directly from wireframing to prototyping. Using Xyzzy, Mighty Media creates functional prototypes and beta websites in the same amount of time it takes most designers to build static photoshop mockups.
