Can anyone recommend a tool (free or cheap, online or desktop) to help build regular expressions, preferably with real-time highlighting of matches.

I've tried searching on this and I seem to get a hotchpotch of old links that are either broken, install adware or simply crash. There must be something decent out there. I'm prepared to reward the programmer with a reasonable fee if the app is okay.

Kind wishes - Patrick

There it is:[^]
I am using it for years.
