Analytics Debugger

Your Single Source of Truth (SSOT) for debugging analytics implementations

Analytics Debugger is your Single Source of Truth (SSOT) for debugging analytics implementations, right inside Chrome DevTools. Formerly known as "GTM/GA Debugger". Open DevTools, pick the Analytics Debugger tab, and every page you load becomes a clear report: what fired, in what order, with what data. Built for analysts, developers and marketers who need to know that tracking does what it should. WHAT'S NEW IN 3.0 A complete rebuild: faster, cleaner, and easier to read. - New report, page by page: each page load (and single-page app navigation) gets its own block, with a tab per vendor - Google Analytics 4: batched hits split into events, server-side tagging responses, and Consent Mode decoded - Consent: CMPs, TCF, GPP and Global Privacy Control in one report - Cookies: what each page sets, changes and removes - New tools: GTM Enhanced Preview, GTM Overrides and DataLayer DB - Command palette (Ctrl+K), themes, and a built-in bug report SUPPORTED VENDORS - Google Tag Manager / Google Tag: dataLayer pushes, containers, tags, triggers and variables - Google Analytics 4: events, parameters, user properties, ecommerce items, consent state (gcs / gcd), server-side responses and the cookies they set - Consent: the CMP on the page and the consent it holds, TCF, GPP and Global Privacy Control signals - Cookies: every cookie the page and its third parties set, with expiry, domain and flags - Other analytics tools: many more web analytics, product analytics and privacy-focused analytics platforms - Marketing pixels: the most widely used ad and conversion pixels TOOLS - GTM Enhanced Preview: start Tag Manager's preview from the panel and keep containers in preview on the sites you debug - GTM Overrides: inject, replace or block GTM containers on chosen sites, even with a delay, to test changes before you publish - DataLayer DB: save any dataLayer push, find it later, and push it again on any page - Data Attributes Inspector: Debug your data- tagged elements. PRIVACY Everything stays in your browser. Nothing you debug is sent anywhere, and the extension only looks at a tab while its DevTools panel is open.
