RegEx visualizer tool [closed]

Question

1 - Is there any software that can get a regex string and render a diagram or some similar stuff that can be used to analyze it. I tried some Windows and web apps, but unfortunately no one provided visualization.

2 - In this page there was a screen-shot of such an app, but nothing else. Does anybody know its name?

Answer 1

The image you have is from The Regex Coach. It is free to use, but they do encourage to give a fee to support it.

I've used the tool a lot previously and can recommend it.

Answer 2

I recently found this http://www.regexper.com/. You can visualize the Javascript-style regex. Very handy. Hope it helps.
