Online Regex Testing

Back in 2004 I posted about The Regex Coach, its a great app that I still use today, however it only really works on Windows so I have been looking for some alternatives.

There is a really great resources called Regular-Expressions.info it even has a cheap tool that you can use to do something similar to The Regex Coach.  Today Lifehacker mentioned RegExr, its a great web app but also has standalone versions for Windows, Linux and OS X, full of sample regular expressions, good explanations of what a regular expression parses as etc, it is a perfect replacement for The Regex Coach, worth checking it out!
