I personally like the Regular Expression Tester.

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

Answer 5

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.

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.
