Just to add, having tried to install...
I'm a partial nerd and probably exactly your audience - I run a small tech agency, familiar enough with PHP to break things but not a proper dev, work on all range of stuff like SEO / content / accessibility / etc... ie - this is exactly the kind of tool I'm looking for to do site audits, content stuff, etc. Normally I find myself reaching for yet another license of Screaming Frog's SEO Spider [0] and find myself groaning at having to pay another £240 p/a - but do it anyway...
Anyway - at first attempt with this I get a "won't install" warning on my Mac. And it's sufficiently scary for someone like me (techy enough to be aware of all the potential things that can go wrong with just installing any old software from the web but not skilled enough to look at the source code and figure out if you're legit or doing something awful to me...) - that I just can't really justify installing it.
Your message about it being notarized and potentially ok to find on the Mac App Store is reassuring at first, but dated 2023.
(I know I have a slight double standard here in that I install Screaming Frog but I've used it for years and know it, whereas you feel fairly unknown...)
So - just some feedback there, I think I'm exactly your audience, and I'd pay for this, given some further signals that it's legit.
