Hi, I'm the developer. That link is (2021), so I'm not sure why it was submitted, but I did just release StopTheScript for Safari Mac a few days ago: https://underpassapp.com/news/2023-9-28.html
Simply because it made browsing the web on iOS possible for me again. I think it would be appreciated by many HNers who haven’t discovered it yet.
I agree only because I don't want to learn JavaScript.
