RegExr

I love RegExr. It is the best app for regex I have ever found. However, this app is quite useless and it doesn't work offline.

It's useful. However, it is not an app. It's a hyperlink. I have to connect to internet to use the function.

Very great App! so useful

Probably this is best one I found over the internet. If there is a bad thing about this app, it is that it does not come out as the first result on Web store when I search for "regex"

This webapp is really good. Beautiful UI, great instant highlighting & syntax help. Great work!

It's only a shortcut, but the website is awesome for working with and referencing Regular Expressions.

Extremely useful and usable. Comes with Help, References, Examples, and Community submitted / voted on Expressions.

Nice! Realtime syntax highlighting and tooltips!

I like it. It's simple, it's easy to use, and it saves a heck of a nightmare researching all those Regex commands for the one that is "assumed" to work. No more having to create custom test cases in my code just to make sure it works properly! Woo!

Love it
