Pixel Helper — Meta, Google, TikTok, Reddit & 20+ more

One pixel helper for your whole stack. Most pixel debuggers only show you one platform at a time. If you run several ad and analytics tools on the same site, none of them can answer the question that actually costs you money: "AddToCart reached one platform but not the other. Why?" Pixel Helper watches all of them at once and tells you. WHAT YOU SEE ✓ Every pixel, measurement and container ID detected on the page ✓ Every event that fired, with value, currency, products and deduplication ID ✓ Whether each event actually left the browser — ad blockers, CSP and consent banners silently kill events the page really did call ✓ Coverage: the same shopper action mapped across every detected platform, side by side, so gaps are obvious ✓ Setup problems: tag present but library never loaded, pixel initialised twice, platform loaded but firing nothing, conversions with no dedup ID (which guarantees double-counting against your server-side API) ✓ Copy report — a plain-text summary for a ticket or a client email Works with the major advertising, analytics and tag management platforms used on ecommerce and lead-gen sites. The full list of supported platforms is on the support page. Built for merchants, agencies and developers who have to prove tracking works before they spend on ads. Privacy: no backend, no account, no data collection. Everything stays in your browser's session storage and is deleted when the tab closes.
