As the release of Jobs’ letter, the debate between Apple and Adobe has reached its climax. However, it is reported that Apple has developed Flash alternative named Gianduia last year.

Apple introduced Gianduia last June at WOWODC. The title of the new alternative came from an Italian hazelnut chocolate, is “essentially is browser-side Cocoa (including CoreData) + WebObjects, written in JavaScript by non-js-haters,” according to a tweet by developer Jonathan “Wolf” Rentzsch.

Apple Retail has actually already been using Gianduia to create web app clients, for a variety of popular programs over the last several months, including its One-to-One program, iPhone reservation system, and its Concierge service for Genius Bar reservations and Personal Shopping programs. It is apparent that Gianduia is well received compared with Cappuccino, SproutCore and JavascriptMVC as the developers can uses it to achieve various dynamic effects without any proprietary web plugin. Just as Rentzsch tweeted, “Blown away by Gianduia. Cappuccino, SproutCore and JavascriptMVC have serious competition. Serious.”

It is likely that more information will surface at this year’s WOWODC and WWDC events.
