Pyjs is a port of Google's GWT to Python. It provides a stand-alone python-to-javascript compiler, an AJAX library, widget toolkit, and general-purpose libraries that resemble desktop toolkits such as pyqt4 and pygkt2.
With Pyjs, rich media applications can be written entirely in python, and deployed for all major web browsers.
Pyjs Native is now included by default, making it possible to run Pyjs applications -- unmodified -- as native Python desktop applications. HTML, CSS, and plugin features remain available, even in the browser version, thanks to ubiquitous browser engine technology. WebKit, XULRunner and MSHTML are the three current available options.
