The Chromeless project experiments with the idea of removing the current browser user interface and replacing it with a flexible platform which allows for the creation of new browser UI using standard web technologies such as HTML, CSS and JavaScript.

Instead building a whole new platform, the web itself should be the platform. That a developer could design the browser using standard web technologies combined with a minimal set of new APIs to interact with the underlying operating system and control the application’s user interface.

This new functionality is exposed as lightweight conventions on top of the DOM and javascript modules exposed via the CommonJS packaging standard.
