Alioramus – Pixel & Tag Debugger

See what your pixels really send: GA4, GTM, Meta, Google Ads, TikTok and more, decoded and checked in a side panel. Local only.

Alioramus shows every tracking pixel and analytics tag your page sends, in plain language. The icon counts the tags on every page you open; click it to open the side panel and see which tags fired, what each event carried, and what is wrong with them. It checks every hit against 100 rules for the mistakes that quietly break attribution: duplicate purchases, missing currency, unhashed emails, consent sent after the tags fired, pixels installed twice, a pixel that loads but never sends. Works with Google Analytics 4, Google Tag Manager, Meta Pixel, Google Ads, TikTok and ten more ad and analytics platforms. - Page: the tags on this page, each event and its parameters, with problems explained. - Issues: what is broken, why it matters, how to fix it, and the event that shows it. - Site: the pages you visited, which tags fired on each, and the site's consent and server-side setup. - Plan: pick what the site should track (e-commerce, lead generation, or drafted from what it sends) and watch each event turn green as you click through. - For specialists: press F12 and open the Alioramus tab for raw requests, recordings across pages, and export to JSON or CSV with identifiers pseudonymised. Everything runs inside your browser. Alioramus has no server and sends nothing anywhere. Chrome asks for access to the sites you visit because a pixel helper needs to see the tag traffic of whatever page you are checking. Alioramus is an independent tool and is not affiliated with or endorsed by the platforms whose tags it decodes.
