Marketing tag QA for the current page PixelCheck — marketing pixel inspector & debugger PixelCheck shows you exactly which tracking pixels fire on a page and what data they send — without digging through the network tab or console. It recognizes the major advertising and analytics platforms, including the Meta Pixel, Google Ads and GA4 (via Tag Manager or direct install), the TikTok Pixel, and the Pinterest Tag. Open any page, click the icon, and every fired event appears with the full data attached to it. What it does • Detects tracking pixels on any website, including Shopify stores that load tags inside sandboxed iframes • Lists every fired event — PageView, Purchase, AddToCart, InitiateCheckout, Lead, and custom events • Shows full event parameters, custom data, and advanced matching fields • Works across all frames on a page, so nothing fires unnoticed • One-click copy for any pixel or tag ID • JSON pretty-print toggle for complex nested values • Show/hide toggle to keep long values out of your way Who it's for • Performance marketers validating conversion tracking before a campaign goes live • Developers debugging tag implementation on staging and production • Agencies and QA teams auditing tracking setups across client sites Privacy PixelCheck reads pixel data only on the page you're actively inspecting. It does not collect, store, or transmit your browsing data. PixelCheck is an independent tool and is not affiliated with, endorsed by, or sponsored by any of the platforms it detects.
