BuildFactory isn't meant to replace Xcode, not in the slightest. I am certain that I'm not the only mac developer that has multiple Xcode projects going at once, such as applications and frameworks, etc, this tool is meant to ease the development of multiple Xcode-based projects at once, helping the developer build everything he needs to.

BuildFactory isn't just for the developers though, many people use open source mac projects, such as Adium, Colloquy, and Growl. Sometimes their release cycles stretch longer than one would like, so you can easily check out Adium's source code (via Subversion), for example, and enable BuildFactory's subversion feature, ot keep up to date builds of Adium.

Continuous Integration has been a focal point of BuildFactory. Using BuildFactory, you can use continuous integration in two ways.

1. Automated builds of everything, on a timer
2. Automated builds of Subversion-based projects, when they are updated

By using BuildFactory as a continuous integration tool, you can spot bugs quicker, and help ease the pain of debugging major applications on the Mac platform.
