Is there any good regex webapps out there?

I'd like to be able to set which type of regex syntax is used, enter some text and a regex and get matches highlighted. Preferably with different colors so it's easy to detect what in the regex is causing the match.

I use the RegexTester to do this, the site is pretty simple and does just what you ask.

I've always used regexlib.com (here is their testing page, they even have a silverlight engine in there which is quite cool). They also have a great library of regexes that people have submitted.

reAnimator is a great regular expression visualizer. It helped me optimize some tricky regexes.
