FAQ
Why was my pixel not detected?
This scan reads the server-delivered HTML. Tags injected later by JavaScript or a tag manager rule may not appear. The free browser extension sees live requests.
Which sites can be scanned?
Only public http and https pages. Private and internal addresses are blocked for safety.
