SproutCore: HTML5 application framework
SproutCore is an HTML5 application framework for building responsive, desktop-caliber apps in any modern web browser, without plugins.
SproutCore works by doing the only thing that can truly eliminate the latency problem: it moves your business logic to the client. SproutCore applications are full-fledged programs, written in JavaScript. That JavaScript executes in your user’s browser, freeing up your servers (and server engineers) to focus on what’s most important in a cloud application: delivering users’ data as quickly and reliably as possible. But SproutCore isn’t your mama’s JavaScript library. It isn’t meant to augment existing web pages. It isn’t meant to add animation to documents. SproutCore is a tool for building applications. It has more in common with Cocoa or .NET than jQuery or MooTools. Because of that, SproutCore will change the way you think about building web apps. SproutCore is server-agnostic and will plug into your existing backend. http://www.sproutcore.com/
