Froth: Objective-C Web Application Framework

Objective C, sure, but cross platform, thanks to Cocotron, an open source implementation of the Cocoa API. http://www.cocotron.org/

It's the first Cocotron-based project I see featured on HN, although it's not the first success story that they could brag about...

The deployment may be cross platform, but to develop with Cocotron you need a Mac. I didn't see the reasoning behind them choosing Cocotron explained on the project page, but it seems like if they really wanted it to be cross platform they should have used GNUstep. It would also be nice to have a comparison between this and GNUstepWeb.

Having a web framework in Objective-C will probably bring a new meaning to code verbosity.

Does the non-Apple runtime support Objective-C 2.0?

"Froth is a Objective-C web application framework that brings the power and simplicity of Cocoa development to the web."

"simplicity" = subjective

True. At least that line did not contain the canned "Simple and Lightweight" dot dot dot.
