Looks like a useful tool. I've been using a similar one: http://regex.powertoy.org/ http://regex.powertoy.org/ The latter supports several languages' regex dialects, and I like the visual way it displays group matches, particularly when groups are nested. It can be a bit clunky, though, whereas Rubular is pretty clean and usable.
