The most powerful free online regexp testing tool is by far http://regex101.com/ - lets you select the RE engine (PCRE, JavaScript, Python), has a debugger, colorizes the matches, explains the regexp on the fly, can create permalinks to the regex playground.

Other online tools:

Windows desktop tools:

Regexbuddy does all this. http://www.regexbuddy.com/

RegexBuddy is great!!!

小开

Rubular is free, easy to use and looks nice.

小开

I use Expresso (www.ultrapico.com). It has a lot of nice features for the developer. The Regulator used to be my favorite, but it hasn't been updated in so long and I constantly ran into crashes with complicated RegExs.

小开

RegExBuddy so far I concur with and endorse.

小开

I agree on RegExBuddy, but if you want free or when I'm working somewhere and not on my own system RegExr is a great online (Flash) tool that has lots of pre-built regex segments to work with and does real-time pattern matching for your testing.

If you are an Emacs user, the command re-builder lets you type an Emacs regex and shows on the fly the matching strings in the current buffer, with colors to mark groups. It's free as Emacs.

Here are some for the Mac: (Note: don't judge the tools by their websites)

小开

I'll add to the vote of Reggy for the Mac, gonna try out some of the other ones that Joseph suggested and upvote that post tomorrow when my limit gets reset.

for online: http://regexpal.com/ for desktop: The Regex Coach

+1 For Regex Coach here. Free and does the job really well.

I am still a big The Regulator fan.
There are some stability problems but these can be fixed by disableing the Intellisense. It gets mad with some expressions and typos in building an expression.

Would love it if Roy Osherove updated, but looks like he is busy with other things.

couple of eclipse plugins for those using eclipse,

RegExr for testing with the Actionscript 3 (whichever standard that may be)

小开

I like to use this online one: http://www.cuneytyilmaz.com/prog/jrx/ Of course, it'll be javascript regexp, but I've never yet done anything clever enough to notice the difference.

小开

How much is your time worth? Pay the $40 and get RegexBuddy. I did, and I even upgraded from 2.x version to 3.x. It has paid for itself many times over.

I use the excellent and free Rad Software Regular Expression Designer.

If you just want to write a regular expression, have a little help with the syntax and test the RE's matching and replacing then this fairly light-footprint tool is ideal.

小开

In the standard Python installation there is a "Tools/scripts" directory containing redemo.py.

This creates an interactive Tkinter window in which you can experiment with regexs.

小开

In the past I preferred The Regex Coach for its simplistic layout, instantaneous highlighting and its price (free).

Every once in awhile though I run into an issue with it when trying to test .NET regular expressions. For that, it turns out, it's better to use a tool that actually uses the .NET regular expression engine. That was my whole reason to build Regex Hero last year. It runs in Silverlight, and as such, runs off of the .NET Regex Class library directly.

小开

Kodos of course. Cause it's Pythonic. ;)

小开

I personally like the Regular Expression Tester.

It's a free firefox plugin, so always on!

小开

Also this regex plugin can be useful for eclipse and idea users.

小开

I like http://regexhero.net/tester/ a lot

小开

Check out Regex Master which is free and open source regular expression tester

小开

http://rgx-extract-replace.appspot.com has the functionality to enlist the captured regex groups formatted in columns and optionally can replace the matched patterns in the input text.
