I just uploaded the desktop version of RegExr. It's just an AIR version of the online application for now, but I'll add some desktop specific features, and put up a nicer looking page when I have a chance.
With this morning's announcement of the AIR alpha for Linux, this means RegExr is now the first free tool for editing and testing regular expressions (RegEx) that runs on Mac OSX, Windows, Linux, and online (as far as I can determine). Pretty cool, considering it only took 60 minutes of work to convert the online application to a desktop program and add update notifications.
You can install the desktop version of RegExr here. Or, you can use the online version at regexr.com.
Next up, I plan to add support for testing replace functions, and then a proper lexer.

The online version of this tool saved me a lot of time over the weekend, so I'm very happy I found a desktop version of it also. Thanks! Hope you have time to develop it further. One feature that comes to mind for the AIR app would be the ability to store the expressions you create in a side panel for later use.

Love it! This is a lifesaver, thank you! I am using the AIR version.

I just found your site today, and was able to solve two problems. You site might save me 100's of hours a year, by making it possible to make some of our developers fish for themselves.
