brew is a package manager, I can install a set of applications and libraries that will be kept up to date with a simple command line. If your coding doesn't take you outside of what Apple provide then you are probably not missing anything.

Personally I have the Android SDK and NDK, QtCreator, Qt5, cppcheck, cloc, mongodb, node, wine and others. If you are not using a variety of 3rd party tools to produce/automate your work then you probably don't need to worry.

Having all those kept up to date for me saves me so much time.
