Custom Mappings
Analytics platforms use parameter names that don't match what your team calls things internally. Define custom aliases for any vendor so the debugger displays your own naming conventions. Supports GA4, Google Ads, Adobe Web SDK, Facebook, Bing, TikTok, Pinterest.
DataLayer Simulator
Push synthetic events directly to the dataLayer without touching your codebase. Test how your GTM tags respond to specific event structures before deploying any code. Essential for QA workflows.
Consent Mode Checker
Full audit of analytics_storage, ad_storage, ad_user_data, and ad_personalization in one dedicated view. Inspect the complete GTM consent command history plus Bing UET and Shopify consent state, refreshed on demand.
Built-in Checks
Automated validation runs on every session with zero setup. Catches GA4 ecommerce events missing an items array, purchase events missing transaction_id or currency, invalid measurement ID formats, and absent consent signals.
Browser Storage Manager
Read-write access to Cookies, LocalStorage, and SessionStorage in one panel. No navigating the DevTools Application tab. Built-in Base64 decoding for analytics and consent cookie values.
Vault
A notes system built into the extension for capturing findings as you debug. Organized by site and page URL, tagged for easy retrieval, and exportable as JSON for team handoffs. Nothing ever leaves your browser.
