Cappuccino is an open source framework that makes it easy to build desktop-caliber applications that run in a web browser.


Features  

Objective-J code

Lightning Objective-J Language

Objective-J is a powerful object-oriented language which compiles to run in the browser. Because Objective-J is a superset of JavaScript, it's easy to mix and match. Objective-J extends JavaScript with traditional inheritance and Smalltalk/Objective-C style dynamic dispatch.

Fish Stunning Controls

Cappuccino's AppKit ships with a huge number of controls, each polished far beyond what's expected on the web. You can quickly build complex apps without reinventing the wheel every time you need a scrollable, sortable, virtual, auto-saves-column-settings table view.

Paint brush Interface Builder

If you have a Mac you can build your Cappuccino user interface in Xcode's Interface Builder, just like you would in Cocoa. Skip the tweak-coordinated-rebuild-test cycle and just place labels and buttons where you need them. The XcodeCapp utility will do the rest.

Cocoa on the web: 280 North, Objective-J, and Cappuccino

...from what I have experienced using 280 Slides, a future with Cappuccino based-apps is a bright one.

Why Objective-J, Cappuccino and SproutCore are completely changing the web app industry

...if you use Cappuccino, those apps will automatically look and behave like ... desktop apps - with zero learning curve on the developer's side. He or she can simply focus on building an kick ass app instead of trying to re-invent basic UI functionality every single time.

An interview with 280 North on Objective-J and Cappuccino

I can see the allure of Objective-J / Cappuccino for building desktop-like Web applications. It gives you a very high level abstraction over the browser. No more DOM. No more CSS layouts, which can be the bane of your existence for a complicated and dynamic layout.

Cappuccino 0.9.7

After nearly a year's worth of work we are truly excited to introduce Cappuccino 0.9.7, a major update to the Cappuccino framework featuring a massive number of new features.

Since Cappuccino is such a wide framework, ranging from a low foundations such as our Objective-J compiler, all the way up to the full featured, fully themable UI kit AppKit, it's incredibly hard to summarise all the changes. But here's our best stab at it:

Cup - The File Upload Framework

A common need for Cappuccino apps is the ability to upload files. Until now, the only native Cappuccino upload solution was DeepDropUpload by David Cann. While DeepDropUpload works, it hasn't been updated in two years, and it doesn't integrate directly with Interface Builder.
