What is MacGap?

MacGap provides HTML/JS/CSS developers an Xcode project for developing native OS X App. These Apps run in OS X's WebView and take advantage of WebKit technologies.

MacGap exposes a JavaScript API for OS X integration, such as displaying native notifications or writing data to a file. MacGap is extremely lightweight and nimble; a blank application weighs less than 1MB.

Mac App Store compatible

MacGap makes use of WebViews which is a standard feature that is available when developing native OS X apps within Xcode. The API that is added is also based on official API's provided by Apple. Therefore there are no dirty hacks, no embedded chrome browser or anything that would stand in your way for Mac App Store submission.
