Feature by feature
Where LoupeKit stops, and why
- People Also Asked extraction
- It works by reading Google’s result pages, which means running on google.com and every country domain it has. LoupeKit holds no host permissions and reads only the tab it was opened on, by request.
- Right-click into Ahrefs, Moz and Semrush
- Each of those is a paid service with its own account, and a shortcut to them is a link to somebody else’s product. The Developer tab’s validators open free public checkers instead, and say in the group that the address is sent.

If SEO is your job and most of your day is spent between search results and the SEO suites.

Pick LoupeKit if
If the question is why a page is not doing what its tags say: what the result really looks like once it is cut off, what a crawler gets before scripts run, which bots robots.txt actually admits, and whether an answer engine can read the page - alongside the stack, the layout and accessibility.
