Extension Metadata

About this extension
Every website you visit is being watched. Not just by the site itself — by dozens of invisible third parties embedded in the page. Tracking Pixel Inspector makes the invisible visible.

WHAT IT DOES

→ Detects 1×1 tracking pixels hidden in images
→ Finds invisible iframes used as beacons
→ Identifies tracker scripts from known data brokers and ad networks
→ Shows a badge count the moment trackers are found — no clicking needed
→ Breaks down results by category: Social, Analytics, Advertising, Marketing

CATEGORIES COVERED

🎯 Social — Facebook Pixel, Twitter Analytics, LinkedIn Insight, Snapchat, TikTok, Pinterest, Reddit
📊 Analytics — Google Analytics, GTM, Hotjar, Segment, Mixpanel, Amplitude, FullStory, Microsoft Clarity, Heap, LogRocket, Mouseflow, and more
📢 Advertising — Google DoubleClick, Google Ads, Amazon Ads, Criteo, Microsoft Ads, AppNexus/Xandr, Quantcast, Rubicon, Taboola, Outbrain, and others
✉️ Marketing — HubSpot, Klaviyo, Intercom, Marketo, Salesforce Pardot, OneSignal

HOW TO USE

Browse normally — the badge updates automatically as trackers are detected
Click the extension icon to open the inspector panel
Expand any category to see which trackers are present and their source URLs
Hit "Rescan page" to re-detect after dynamic content loads
THIS IS NOT A BLOCKER

Tracking Pixel Inspector does not remove or block any trackers. It only reveals what is already there — helping you understand why ads seem to "read your mind" across different websites. Think of it as a flashlight, not a firewall.

🔒 PRIVACY

No data is collected, stored remotely, or shared. All detection runs entirely in your browser. The extension never reads page content or transmits anything outside your device.
