Before Steve Jobs rejoined Apple in the 1990s, one of the flagship projects at his company, NeXT, was WebObjects, a set of tools for making what were called at the time “internet applications.” Today we just call them websites.
Well, not quite. Websites cover pretty much anything you view online, while WebObjects was revered for its backend capability.
WebObjects was ahead of its time, and when Apple bought NeXT, it adopted the framework and even uses it to run parts of the online Apple Store even today. But WebObjects hasn’t been updated for external developers since 2008.
WebObjects has been on life support for year, despite still being used at Apple.
