Microsoft Silverlight and Adobe AIR are cross-device platforms that run advanced web applications locally on computers.
Mozilla is now readying the release of their open-source project, Prism, which will make it even easier for you to turn most web pages into applications usable directly from your computer.
The current Prism beta that is available is very stable, and according to a source from Mozilla, Prism will be stable enough to be bundled with the upcoming Firefox version 3.6.
Prism works like this: while you are on a web page, simply right-click, and turn the page into an app via the option, and that’s it, you’re done. You can also manually enter URLs into Prism to create applications. Prism currently works on Windows, Mac, and Linux operating systems.
So you might be asking yourself what all of this is about, essentially, the apps that run on these platforms are richer in features compared to apps within web browsers. Prism (with the other platforms) could make life easier for you. For example, you can head over to the FedEx website, and create an app to easily use from your desktop to track parcels. Another example is the NASDAQ Market Replay app (on Adobe AIR), a stock market analysis tool that works well because of the ability to store and manipulate significant amounts of historical data from the web thanks to Adobe AIR. Other possible uses are to create apps from your favorite email service like Gmail, that will allow you to get notifications on your desktop when new emails arrive. For example, if you get your email with Yahoo Zimbra, the current app displays notifications as emails arrive, as seen in the screenshot below on the Mac OS X dock.
The main advantage for Prism is that because it is an open-source project compared to proprietary technology used by Silverlight and Adobe AIR, opting to develop for Prism could cost companies less and could be a faster process with more extensive available support.
Despite the popularity of AIR and Silverlight, Mozilla has one significant competitive advantage: Firefox. With over 300 million downloads of the popular web browser, bundling Prism, a lesser known technology to the average computer user, could spark mass adoption assuming the users find value in using the apps on their machines locally compared to accessing their favorite services from their respective browsers.
