1. Snap-CSS an open-source css editor for windows. Snap{css} is an extremely light-weight, notepad-like application that allows css designers to easily edit their code in a familiar environment while having quick acccess to helpful features such as our beautify and collapse functions.

2. Amaya is a Web editor, i.e. a tool used to create and update documents directly on the Web. Browsing features are seamlessly integrated with the editing and remote access features in a uniform environment. This follows the original vision of the Web as a space for collaboration and not just a one-way publishing medium.
