Nub displays differences in folders in an efficient and beautifully stylish way. Nub makes identifing changes in folders quick and easy by displaying what's important and hiding what isn't.
Nub compares any number of folders, it is not limited to comparing just two. Nub lets you save comparisons, so if you need to compare the same folders frequently, you can re-run the comparison later.
For file level comparison, Nub integrates with other apps. It auto-detects Kaleidoscope, Changes, Araxis Merge, TextWrangler, BBEdit and FileMerge and you can use your own custom tool as well.
