TagProof — Analytics & Pixel QA Inspector

About

SEE EVERY ANALYTICS & AD TAG THAT FIRES — AND CATCH THE BROKEN ONES BEFORE THEY WASTE AD SPEND.

A dead conversion pixel or an event firing the wrong value means weeks of ad budget optimized on
garbage data — and a furious client. TagProof shows you exactly which analytics and ad tags fire on
any page, and flags the ones that are broken, duplicated, or missing required data. One click. No setup.

🔍 EVERY TAG, ON ANY PAGE
Click the icon and TagProof lists every analytics and advertising tag that fired. Get a clean breakdown of measurement IDs, event names, values, currency, consent state, and HTTP status codes. Works with major analytics, ad, and marketing platforms.

🚦 AUTOMATIC QA CHECKS
TagProof flags the issues that quietly cost money:
• Duplicate events firing 2× (double-counting your conversions)
• A vendor running under two measurement/pixel IDs (dev + prod mixed up)
• A purchase / Purchase event missing value or currency (your ROAS will be wrong)
• A beacon that returned an HTTP error or got blocked
• A tag library loaded but firing zero events
• Google tags firing with no Consent Mode signal (gcs) — for EEA traffic & the GA4↔Ads consent split

🔒 100% LOCAL & activeTab-ONLY
TagProof only inspects a page when YOU click the icon. No "read all your websites" permission, no
background access, and no page content ever leaves your browser. It even recovers tags that fired on
page load — without any broad permission — by reading the browser's own Resource Timing data.

🧷 BASELINES & MONITORING (PRO)
Save what a healthy page fires as a baseline; TagProof then flags any expected tag that goes MISSING
— the silent breakage free tools never catch. Point it at your own free Cloudflare Worker for a daily
liveness check with Slack/Discord/email alerts when a tag dies.

⚠️ HONEST LIMITS (please read)
The extension deep-inspects tags only while you have the page open. The optional Pro Worker does a
cheap daily HTTP liveness check — it can't run a browser, so it can't confirm an event fired correctly.
TagProof reads tag requests the page already makes; it does not modify your tracking.

PERFECT FOR
• PPC & analytics agencies validating client conversion tracking
• Ecommerce teams whose tracking numbers don't match store backend values
• Growth & marketing leads QA-ing a campaign landing page before launch
• Developers shipping tag manager changes who need a fast sanity check
