Does this tool actually calculate regex differences? It seems more like a playground to look for the differences oneself.

In any case, nice work! I've been looking to understand more of the mechanics of regex-to-dfa translation myself.

Yeah there's a little space under where you enter the different regexes where it shows you information including the differences
