Regular expressions apps for Mac


Regular expressions are a good tool for text automation. Which apps would you recommend to try regular expressions on a Mac? RegExRX is a good one, but it is not optimized for High Sierra and perhaps will not work in the future.


I don’t have a recommendation to pass along yet, but have recently been spending some time with Expressions.

There’s a free trial available and it’s included in Setapp.


Not an app, but a website, Regular Expressions 101 is an online playground where you can build and test regular expressions. You can also choose the “flavor” of regex that you are targeting (i.e., php, javascriot, python, golang).


Another vote for Regular Expressions 101. It’s my goto and because it is web based so I can use it on pretty much any platform I might be working on at the time :sunglasses:

@misterharrycrumm’s observation about the language/flavour variance is a key feature to be aware of and it is absolutely the difference between pulling your hair out and sitting back with a smug look on your face.


Thank you for your suggestion. I have been playing around with Expressions. It is quit basic, but has a nice, clean interface, allows to save user’s RegEx and includes a good cheat sheet.


Thank you (thanks also to @misterharrycrumm . Regular Expressions 101 is great an free. Of course an internet connection is needed, but is good that I can also use it on iOS. The ability to choose the “flavour” is very useful.


You’re very welcome, @Pedro. I appreciate you sharing some feedback on Expressions.


Been a while since I last used it, but I’ve used Patterns often


Thank you, @martijnengler I will give it a try.


Bit late, but +1 for Patterns
