Turn your web app into a Mac Desktop App with Fluidium
Fluidium is a open source platform for developing Rich Internet Applications that run as native Mac OS X desktop apps. It’s very similar to Adobe Air platform except fluidium is open source (liberal Apache license), and exclusive platform only for Mac.
With Fluidium, 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. Fluidium is unabashedly 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 completely based on the same open source technology that powers the popular Mac OS X Site Specific Browser, Fluid.
