Just as with MobileMe, iCloud Web seems to be done with SproutCore and a bit of jQuery[1]. Though it feel funny when they recreate the iOS-style scrollbar with JavaScript, despite Lion already has such a thing... (not to mention the scrollbar is inconsistent between Contacts and iCloud Calendar) I'm honestly surprised at how "complete" these apps are. At least with Calendar and Contacts, they works exactly like its iPad/OSX equivalent.
