IsPixelWorking

IsPixelWorking checks the ad tracking on a web page and tells you what is broken and how to fix it. Give Claude the page your ads point to. A Chrome browser in the EU visits it twice: once without touching the cookie banner, and once arriving as if from an ad, with cookies accepted and the main buttons clicked. It records what the page tries to send to ad platforms and grades the Meta, TikTok and OpenAI (ChatGPT Ads) pixels separately.

The report covers tracking that fires before consent or stays silent after it, duplicate events, missing event IDs, lost ad click IDs (fbclid to the _fbc cookie, ttclid), extra pixels and signs of server-side tracking. Each problem comes with a step-by-step fix guide for Shopify, WordPress, Webflow, Framer or any other site, and there are guides for Cookiebot, CookieYes, OneTrust, Usercentrics and Complianz. After you deploy a fix, Claude can run the check again to confirm it.

Free, no account needed. A check takes 20 to 60 seconds, and results from the last 24 hours are reused.

What it does not do: it sees the browser side only, so it cannot prove that Meta or TikTok accepted server events (Conversions API); only the ad account shows that. It never fills in forms, never clicks buy or checkout buttons and never forwards tracking data to ad platforms, so purchase events are not tested and the site's ad accounts get no test data. It runs from the EU only. Other ad platforms (Google Ads, LinkedIn and others) are listed but not graded. Findings describe technical behaviour, not legal compliance.
