Go Regexp debugger?

[Steve Mynott]

I'm aware of https://regex101.com/ which is fine 90% of the time for
debugging go regex, but I did find an edge case where it misled me a
few years back.

There was a specific website which used go on the backend to do
something similar with more compatibility, but I can't find details
and think it disappeared anyway, I'm sure I saw a repo for this?

Does anyone remember what I'm talking about?

Alternatively, are there any command line go regexp debuggers. I used to use

https://metacpan.org/pod/Regexp::Debugger

when I used Perl and something similar for go would be great if it existed?

To (partly) answer my own question.

The Heroku link is dead, but the code runs fine locally with an added
go.mod file.

For Windows, there's regexbuddy.com and regexmagic.com.  These work together to help debug regexp's.  But these are not free programs.
