Have you seen www.debuggex.com? It's very visual and gives you real-time feedback for quickly understanding a regex. — Sergiu Toarca

From my answer to this question:

I think you will find www.debuggex.com very valuable. Some advantages of debuggex are:

Feedback is in real-time, so you can understand what's happening faster
The ability to answer the question "Why does/doesn't it match here?" for any position in your text.
Very heavy on the visuals, it was a core design decision behind it's creation

At the time of writing, it only supports Javascript. However, more languages are planned for the future.

Excellent tool. Wish I could upvote more. A bit of a learning curve but the video helps a lot.

A very good (though not free) regex tester, debugger and converter is RegexBuddy. It's especially handy if you need to convert regular expressions from one flavor to another, and there is a grep tool built in.

Rubular

It's actually for Ruby but it's pretty good for testing most standard regex. It allows lookbehind though which Javascript does not implement.

Apologies, it doesn't allow lookbehind!

There are differences, yes. There can even be slight differences in how regex is implemented between browsers (e.g. IE's "JScript" variant vs. Firefox), surprise surprise.

You should find plenty of JS-oriented regex testing tools on the web though. For example, I've used this one in the past, which is written in Javascript:
