What is actually tracking your site?
Paste any URL. We read the page source and report which analytics and advertising tags are really there, which are stale, and what looks wrong.
Reads one page's HTML source only. Tags loaded through Tag Manager will not appear, because they are injected after the page loads. We do not keep the URLs you check.

Source tells you what loaded. It cannot tell you whether the events behind it fire on the right actions, deduplicate properly, or match what your ad platforms report. That part takes opening the accounts.
