Event Watcher

Watch analytics, GTM and consent events in real-time. 500+ platforms, optional AI features, all in Chrome DevTools.

See every tracking event on your website in real-time. One DevTools panel replaces the need to switch between multiple vendor-specific debuggers. WHAT IT DOES Event Watcher captures four types of tracking activity as it happens: - Network Tracking Requests: HTTP requests sent to analytics, advertising, and marketing endpoints - DataLayer Pushes: Events pushed to data layers across multiple implementations - Script Loads: Tracking scripts loading on the page, with full initiator chain showing how each script was loaded - Navigation Events: Page URL changes via History API, popstate, and hash changes BROAD PLATFORM COVERAGE Detects 400+ tracking platforms across 14 categories including analytics, tag managers, advertising, customer data platforms, consent management, session replay, ad tech, A/B testing, and marketing automation. Each detected platform is shown with its official icon, brand color, and category badge for quick visual identification. FOUR VIEW MODES - Stream View: Chronological event stream with platform icons, timestamps, and contextual badges - Tool View: Events grouped by category and platform - Page View: Events grouped by domain and page URL - Script Tree View: Dependency tree showing which scripts loaded which DEEP EVENT INSPECTION Click any event to inspect its full payload: parsed parameters in human-readable tables, custom data (event properties, user properties, traits), e-commerce data, consent signals, cookies set, raw request details, and script dependencies. 35+ platforms have dedicated parsers that transform raw request payloads into structured, readable output with labeled sections and grouped parameters. SCRIPT INITIATOR TRACKING Every script and request is classified by how it was loaded: directly by the page, by a tag manager, or by another third-party script. Uses stack trace analysis to build a complete dependency tree of all tracking tools on the page. CONSENT STATE TRACKING - Detects 40+ consent management platforms and reads consent state from cookies, browser APIs, and data layer events - Tracks consent mode parameters across major analytics tags - Shows a consent timeline: initial defaults, consent platform loading, user choices, and updates - Highlights potential compliance issues such as tracking before consent or after denial TAG MANAGER HUB & CONTAINER INTERCEPT - Container intelligence: version info, tag/variable/trigger counts, and script dependencies - Container actions: block, swap, inject, or preview tag manager containers for debugging - Rules persist across page reloads SEARCH & FILTERING Keyword search, platform filter, category filter, script filter, consent filter, interaction filter, and saveable filter presets. Filter combinations let you isolate exactly the events you need. COPY & EXPORT - Copy individual events as JSON or tab-separated table - Export the full event stream as HAR - Export consent timeline as JSON CUSTOMIZABLE Configurable defaults for stream direction, sort order, filter states, and data layer nesting. Add custom tracking endpoints for internal or uncommon platforms. Resizable panels, keyboard navigation, and dark mode (follows your DevTools theme). MULTIPLE ACCESS POINTS Use it as a DevTools panel (primary), Chrome side panel, toolbar badge showing active tool count, or popup for a quick overview. WHO IS THIS FOR? Built for web developers, analytics engineers, QA teams, marketing technologists, and privacy/compliance professionals who need to debug, audit, or validate tracking implementations.
