Overview
Instantly reveals which analytics and marketing tags are running on any website — with tracker IDs, right from the toolbar.
TagCheckerKI is a marketing audit tool that shows which analytics and tracking technologies are installed on any website — without opening DevTools. How it works Click the extension icon on any page. TagCheckerKI automatically reloads the page, intercepts all outgoing requests, and displays detected tools with their IDs in a clean table. Tags appear in real time as the page loads. What you can detect The extension recognizes over 40 popular platforms across several categories: Analytics platforms — including session recording and product analytics tools used to measure user behavior and site performance. Tag management systems — containers that load and manage third-party scripts on a page. Advertising and retargeting pixels — scripts that track conversions and enable audience targeting across ad networks. CRM and end-to-end analytics — platforms used for lead management, sales tracking, and revenue attribution. Call tracking services — tools that assign phone numbers to traffic sources for offline conversion measurement. Live chat and support widgets — customer communication tools embedded on a page. Push notifications and email marketing — subscription and messaging platforms loaded via script. Key features Shows tracker IDs directly in the popup — no need to dig through page source or network requests manually. Flags deprecated technologies in red so you can spot outdated implementations and recommend upgrades. Real-time detection — tags appear as they are fired during page load. One-click ID copy for quick reference. Works as both a toolbar popup and a DevTools panel. Search and filter to find a specific tool on complex pages.
