RegExr vs Debuggex opinions
pros, cons and recent comments
benhampson Debuggex's best feature was the visualiser. I can't find another site that has exactly that, but the RegExr explainer at the bottom of the page is a good alternative. Plus, the interface is clean, the cheatsheet is handy, and the 'Community Patterns' are helpful.
