Apple’s iCloud built using the SproutCore framework
Apple’s new iCloud Web apps are built using the same SproutCore Javascript engine that was used throughout MobileMe. If the favicon above doesn’t prove it, looking at the underlying code below seems to offer undeniable evidence.
SproutCore describes itself as an open-source framework for building blazingly fast, innovative user experiences on the web.
Here’s a nice interview with Charles Jolley, one of the founders of SproutCore and previous MobileMe Javascript Frameworks Manager. He left Apple about a year ago to start Strobe – a device agnostic Web publishing engine based on…you guessed it, SproutCore.
Interestingly, SproutCore lists Strobe Inc. as its parent company.
