Tag Inspector — Meta Pixel, LinkedIn & GA4 Tag Detector

Tag Inspector helps you understand your website’s tracking: which tags are detected, what events they send, and where the setup may need attention. Open the side panel to see tracking IDs and captured events as you browse. Inspect event parameters, explore the data layer, and review findings with clear explanations and suggested fixes—including duplicate tracking signals and purchase events missing a transaction ID. Detection combines page HTML, network requests and JavaScript signals, including supported tags that load after the page opens. Explore six sections: • Overview — detected platforms, tracking IDs and a checks score. • Activity — captured events and their decoded parameters. • Consent — available consent signals, including Google Consent Mode. • Data — captured data-layer events and values. • Issues — configuration warnings and suggested fixes. • Report — a printable summary of your observations. Inspection runs locally on your device. The full privacy policy is linked from this listing. Tag Inspector is free to use. Built by NUVIX.
