Detect header bidding, ad servers, SSPs, CMPs, identity & consent tech

More than a boring CLS tool

Check the health of your prebid implementation and all the connected ad servers, SSPs, CMPs, identity and consent tech.
Get a detailed report of all detected tags, their categories, and how they interact with each other.

Header bidding detection.
See exactly which SSPs a publisher has configured in Prebid.js, their bidder timeouts, price floors, and whether re-auctioning is enabled on refresh.
CMP & consent tech.
Identify which consent management platform is running, whether GDPR and GPP are configured, and if consent is being passed correctly to bidders.
Ad server fingerprinting.
Detect GAM, AdSense, Xandr, Smart AdServer and more — including version info, lazy loading config, and single request architecture status.
Identity & data solutions.
Surface identity tech like Unified ID 2.0, LiveRamp, ID5, and first-party data tools that publishers use to maintain addressability without third-party cookies.
Performance signals.
Measure real page load time, LCP, total blocking time, and how much of that blocking time is attributable to ad tech loading on the page.
Network request inspection.
See every ad-related network request fired during page load — tagged by technology, with payload sizes so you can spot bloat at a glance.
