JavaScript & CSS Code Usage
See how much of each JavaScript & CSS file loaded on a page is actually used.
It's worth noting 100% usage is not a realistic goal for most websites. You can also use Chrome devTools, find out how here: Google devTools Doc
You can also download the JS / CSS files with just the used stuff, but be aware, these are not meant to be replacements, classes and functions may get missed, and replacing your sites files with these may very well break something!
Getting Blocked? site owners might well choose to block tools like this, especially if they are pretending to be Googlebot.
If you are testing your own site, you can find the IP ranges used by this tool here ttb-ipranges.json and allow list them in your firewall or security plugin.
