Tracking Health Scanner

A real Chromium browser loads the page and records every network request. You get a graded report of what fired, what fired twice, and what fired before it should have.

Public pages only. Initial load, desktop viewport, US locale, no clicks. Reports get a shareable link; 10 scans a day per person.

What it checks

What a single page load can't tell you

Whether add_to_cart carries value, whether the purchase event fires once on the thank-you page, whether tags behave after Accept. That needs a scripted journey replayed on a schedule — which is the monitor we're building next.
