What's really cool is that he breaks the code down into small pieces and shows you how everything is connected. He's a lifesaver when you need to understand some old software that no one has documented. He produces super clear diagrams and shows you in two seconds what depends on what. For maintenance, it's absolutely vital! Review collected by and hosted on G2.com.

The downside is that it's a purely technical tool; if you're not familiar with code, you'll struggle. The interface is a bit clunky and not very user-friendly. When the project is huge, it gets a bit slow, and you have to wrestle with the options to get the analysis to complete without crashing. Review collected by and hosted on G2.com.
