A Mozilla Labs project developed to remove and replace the traditional Web browser user interface with a more flexible platform that enables new browser user interfaces using Web technologies like HTML, CSS, and JavaScript. In short, Chromeless (currently inactive) is designed to enable developers to build desktop applications with common Web development technologies.
The Chromeless project is a more ambitious undertaking that takes over for Mozilla Labs recently retired Prism project, which allowed users to create desktop-like apps from individual websites. Chromeless utilizes the Python programming language and the same rendering engine found in the Mozilla Firefox 4 Web browser, and is available for major operating systems such as Mac OS X (v10.5 and later), Microsoft Windows (Windows XP and later) and most versions of Linux.
Chromeless is not affiliated with Google nor does it share any relation with the company’s Google Chrome Web browser.
