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 site in real-time — one DevTools panel replacing a stack of vendor-specific debuggers. WHAT'S NEW IN VERSION 1.4.2 Consent detection fixes and broader tool coverage: ▪️Consent platforms served from regional data centres are now detected. Sites whose consent banner is served from an EU, UK, Asia-Pacific or Australian data centre previously showed no consent platform at all — those setups are now recognised, including the moment a visitor's choice is saved. ▪️13 newly supported tools across analytics, marketing automation, widgets, A/B testing, session replay, CDPs, and more, so more of what a site runs is recognised out of the box. ▪️Wider coverage of tools you already track — new endpoints added to platforms already supported, whose actual tracking data was showing as Unknown while only their loading script was recognised. WHAT IT DOES Event Watcher captures four types of tracking activity as it happens: ▪️Network requests to analytics, advertising, and marketing endpoints ▪️DataLayer pushes across multiple implementations ▪️Tracking script loads, with the full initiator chain showing how each script was loaded ▪️Page navigation (History API, popstate, hash changes) 500+ platforms are detected across analytics, tag managers, advertising, CDPs, consent management, session replay, ad tech, A/B testing, and marketing automation. Each one is shown with its official icon, brand color, and category badge. VIEW MODES Stream (chronological), Grouped (eight pivots — Tool, Page, Event Name, Consent Category, Datalayer, Endpoint, Cookie, Identity), Script (dependency tree of every tracking script on the page), Stack (the site's martech stack at the tool level), and Pinned (a per-domain parking spot for events that survives Clear and reloads). DEEP EVENT INSPECTION Click any event for parsed parameters in readable tables, custom data, e-commerce items, consent signals, cookies set, raw request details, and script dependencies. 30+ platforms have dedicated parsers that turn raw payloads into structured, labeled sections. CONSENT TRACKING ▪️Detects 40+ consent management platforms ▪️Reads consent state from cookies, browser APIs, and dataLayer events ▪️Tracks consent mode across major analytics tags ▪️Shows a full consent timeline: defaults, CMP load, user choice, updates ▪️Highlights potential issues such as tracking before consent or after denial TAG MANAGER TOOLS Container intelligence (versions, tag/variable/trigger counts, dependencies) and container actions — block, swap, or preview — with rules that persist across reloads. SEARCH, FILTER, EXPORT Keyword search plus platform, category, script, consent, and interaction filters — combinable, and saveable as presets. Copy events as JSON or TSV; export the session as HAR; export the consent timeline as JSON. CUSTOMIZABLE Configurable defaults, custom tracking endpoints for internal or niche platforms, resizable panels, keyboard navigation, and dark mode that follows your DevTools theme. ACCESS POINTS DevTools panel (primary), Chrome side panel, toolbar badge with active tool count, and popup overview.
