Pixel Debugger – Meta, GA4, TikTok & 46 more

See what every ad and analytics pixel on a page sends: event names, values, currencies and order IDs, every parameter decoded.

Pixel Debugger shows what the tracking pixels on a website actually send, as it happens, in Chrome's side panel. • Decodes 49 ad network and analytics networks, including Meta, Google Analytics 4, Google Ads, TikTok and Pinterest. The full list is at pixeldebugger.com/networks. • The signal board: one lane per network, one dot per event, page by page, so you see at a glance what fired where. • Exact values: event names, values, currencies, order IDs and products exactly as sent, each with the key it came from. Nothing is guessed or renamed. • Every parameter: for each event, which of the network's supported parameters were sent and which were not. • Catches problems: invalid values and currencies, duplicate events, failed requests, and networks that report different values for the same order. • Setup view: the website platform (12 detected, including Shopify, WooCommerce and Magento), which pixel scripts loaded, consent commands and click IDs. • Record a journey across pages, save it on your computer, and export JSON or Markdown audits. Everything stays on your computer. The extension only observes requests; it never blocks or changes them, and it sends nothing anywhere.
