Prism is a cross-platform application that lets you integrate web applications with your desktop.
Prism now provides a cross-platform way to integrate the web platform with the desktop environment, and developers don’t have to lift a finger to desktop-enable their web applications, while users have the choice to use their favorite web apps in their browser, on their desktop of choice, or in both places.
Prism is the successor to WebRunner, which I wrote about a while ago. Mozilla just released the Linux version of Prism. Prism is a web browser that runs web applications to look and launch as if they were traditional applications.
