Is there a good browser based sandbox to practice regex?

I am looking for recommendations for a browser based regex sandbox to practice some proof of concept expressions.

From stackoverflow
  • I've used http://www.rubular.com/ a few times, seems to do the job.

  • I like RegExPal.com. Good luck.

  • Try NRegEx.

  • This one's pretty good too: RegExr

    John Sheehan : Also has a downloadable AIR app which is nice
  • http://demo.1060research.com/ep+name@app_regular_expression_cookbook

  • For online sandboxes for several different languages, platforms, and open source applications, see this similar SO question.

  • Which flavor? Regex support is included in most of the major programming languages in use today, in editors and IDE's, in command-line tools like grep and findstr, and lots of other places. Every one of these tools/languages/applications has its own regex flavor, and no two flavors are completely alike.

    For the regex flavor of a specific programming language, I just Google for "<language> regex tester"; there always seems to be at least one online tester available.

  • I'm biased of course because I wrote it. But there's a good one for .NET regular expressions called Regex Hero.

  • I wrote my own Regular Expression (REGEX) Online Test Sandbox with a Match and Replace feature since I could not find one with a Replace feature. It's running under a DOT NET (.NET) Engine. Great for testing Regex patterns, but also good for quick and dirty reformatting of text files and strings.

  • This is fairly handy for .net based stuff:
