About Free Website Tracking Checker
Sonar is a free website tracking checker that scans your site and reports what tracking is actually running, including GA4, Google Tag Manager, ad pixels, and dataLayer events. It provides a first-pass tracking audit with evidence for each finding, no account or installation required. Designed for website owners and marketers who need to verify their tracking setup.
What makes it different
Only reports problems it can prove from the crawl, providing validated findings rather than assumptions based on plans.
