Turn Any Webpage into Real Mac App – Fluidium

Fluidium is an open-source platform for developing Rich Internet Applications that run as native Mac OS X desktop apps. It’s very similar to the Adobe Air platform, except fluidium is open source (liberal Apache license) and an exclusive platform for Mac.

You can wrap your existing web app in a pure, native Mac application shell and provide the best of both worlds to your demanding user base.
No Doubt It is Mac-only and makes no cross-platform compromises. With the high quality of native Mac apps, cross-platform, least-common-denominator approaches don’t cut it on OS X. Your Fluidium-based app will fit right in on OS X as a first-class Cocoa citizen.
It is wholly based on the same open-source technology that powers the popular Mac OS X Site Specific Browser, Fluid.
