Free to use. Onlyfy Pro is $5/month for unlimited searches.
Install
Click Add to Chrome above, then Add extension in Chrome's prompt.
Open the Ads Library and run a search. Onlyfy checks where each ad lands and filters out the ones that don't go to a Shopify store. A control bar appears bottom-right.
Your first search is free. After that, sign in with Google or your email to get three searches a day. There's no password.
Why does Chrome say "read and change all your data on all websites"?
Onlyfy has to open each ad's landing page to see whether it runs on Shopify, and advertisers
can link anywhere, so the set of sites can't be known in advance. It checks each store's own
site directly from your browser, reads the response, and stops there. It injects nothing into those sites
and never sends us the pages it reads.

Using it
The control bar, bottom right
Shows how many Shopify ads are on screen and how many were filtered out. Show brings the filtered ones back, greyed out and labelled with the reason, so you can check Onlyfy's work. Hide takes them away again. The gear opens every setting without leaving the page.
Grouping duplicates
One advertiser can fill a whole page with near-identical ads. The grouping button cycles through no grouping, Group by product and Group by store, and is always labelled with the mode it is in. By product is usually what you want: it hides repeats of the same offer but still shows every product a store is testing.
Strict mode
Off by default. Some stores sit behind bot protection that blocks the check. Those stay visible so you never lose a winner. Turn Strict on to hide them too.
Deep check
On by default. When an ad points at a redirect or cloaker page, Onlyfy follows it and asks the destination's storefront API directly. Slightly slower, noticeably more accurate.
Good to know
Lead-gen and app-install ads are always hidden
They have no outbound store link, so there is nothing to check.
Results are cached
Each store is checked once and remembered for two weeks, so repeat searches filter instantly.
Edge, Brave and Opera
All three install straight from the Chrome Web Store link above. Edge may first ask you to allow extensions from other stores.
Prefer to install it manually?
Download the ZIP and unzip it. Keep the folder somewhere permanent. Chrome loads the extension from this folder, so deleting it uninstalls Onlyfy.
Open chrome://extensions in a new tab.
Turn on Developer mode with the toggle in the top-right corner.
Click Load unpacked and select the unzipped folder.
Manual installs don't auto-update, and Chrome will prompt you about developer-mode extensions on restart. The Web Store install is the easier path.
