What's the diff? I love regexr and credit that site to my finally understanding regex.

In fact, I was just on it this morning!

I think regexr does a better job of helping you to understand exactly what is happening in the regex. I typically reach for debuggex when I already have a decent understanding of how to accomplish what I want and just want a simple way to edit & test, I think the interface is less busy for that case.

debuggex makes really nice railroad diagrams.
