I‘ve tried a whole bunch of nicely designed regex apps (and this one seems to fit in), but the one feature that is absolutely essential is support for different regex dialects. Often, they only provide the dialect for the specific language they’re implemented in, and often that’s not even specified. What I usually want to do is to track down subtle differences between Perl, Python, gnu grep, and vim
While the UI was heavily inspired from Expressions, Expressions does have more features including saving expressions locally. If you want a more feature-full app, then definitely get Expressions. Regxr was just a little project put together over a couple of days for fun, and it's truly not an original idea, haha
Wow! I need to remember to give this a try. I usually use https://regexr.com/. I like it because it usually works for all languages and it's served over https. That is always nice!
Edit: For what it is worth, you link serves over https, too. Just not by default.
Looks promising - I found I couldn't edit sample text - anything I typed in the sample area was added to the end of the sample, not the caret position.
