Free tracking scanner
See what ad blockers take. Before they take more.
Enter a website. We read its tags, find its server-side provider, check seven layers of protection and open it in a real browser with an ad blocker.
Six checks. One report you can share.
- 01
The page
Whether it answers, where it is served from, and whether a bot check stands in front of it.
- 02
Tags
Google Tag Manager containers, Google tags, the consent tool and where each script loads from.
- 03
Server-side provider
Stape, TAGGRS, Addingwell, JENTIS, your own Cloud Run or SGTM.space, read from DNS, headers and loader addresses.
- 04
Protection layers
Seven layers compared with the rules EasyPrivacy, AdGuard and uBlock Origin apply to tags.
- 05
A real browser
The page loads twice, as a new visitor and after accepting the cookie banner, and we record every tag request.
- 06
Score and fixes
A score out of 100, what to fix first, and how to move to your own domain.
About the scanner
Is it really free?
Yes. No sign-up and no card. Each visitor gets a few scans an hour, and a report for the same site is reused for a few hours so we do not fetch it again.
What does the scanner store?
The address you entered and what we found there: tags, providers and findings. Never the page itself, cookie values, visitor identifiers or your IP address. Reports are deleted after 30 days.
Does it work if I use Stape, TAGGRS or my own Cloud Run?
Yes. The scanner reads any website and names the server-side provider it finds, with the evidence, and lists what you would repoint to move.
Will the scan show up in my analytics?
The browser pass is a real page view, so it can appear as one visit. Its user agent ends in SGTMspaceAudit/1.0 if you want to filter it out.
