When I was doing advent of code 2020 in julia, I noticed there were no good resource like [pythex.org](http://pythex.org) to test out the julia regular expression results. Looking up resources to host a simple web app that can solve this. Can you point me to resources with regards to

1. creating julia web app (i did looked up, genie, webio, interect); are there blogs/threads/videos that makes creating a no-brainer simple julia web app ?
2. Hosting services. what are the options other than heroku / aws for hosting julia apps easy

Do you often find that the generic online regex testers do not correspond to Julia’s implementation? I think that Python needs those online tools because their implementation is non-standard ([regex - Perl compatible regular expression (PCRE) in Python - Stack Overflow](https://stackoverflow.com/a/7066413)).

Edit: Julia has Perl compatible regexes ([Strings · The Julia Language](https://docs.julialang.org/en/v1/manual/strings/))

Try this and set to PCRE: [https://regexr.com/](https://regexr.com/) (courtesy of @ferrolho)

I have also found that [https://regex101.com/](https://regex101.com/) works quite well for testing Julia regex’s.

Ok. I was under the assumption python regex follows the standard 🙂
