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 1.4.0 Clearer event inspection and more consistent tool names across the panel: ▪️Data layer detail views — client-side data layers from more tag managers now open in dedicated data-layer views (the data the site pushed, plus the full computed state), matching the existing Google data-layer view. ▪️Easier-to-read JSON — dataLayer and JSON sections get bigger expand arrows, indent guides, row highlighting, and click-anywhere-to-collapse. Open any section in a larger window when a payload is too big to scan inline. ▪️Self-describing Unknown events — unrecognised tracking requests now show their endpoint host in the stream and as a filter chip, so you can tell what's firing at a glance instead of seeing a generic "Unknown" row. ▪️Copy dataLayer Pushes — a lighter export of just what the site pushed to window.dataLayer, alongside the existing full export that also includes the computed state for tag-manager debugging. ▪️Consistent, current tool names — every tool reads the same in the stream and in its filter chip, and vendors now use their current official product names under consistent logos. ▪️Consistent AI privacy — the privacy scrubbing that protects the opt-in AI features now covers the whole chat, not just the first question. ▪️Sharper detection and steadier long sessions — fewer false positives, fuller consent-platform coverage, lighter memory use, and a more accurate consent counter throughout. ▪️Better vendor decoding — first-party (proxied) Adobe Experience Platform traffic now decodes into its full readable breakdown instead of a generic proxy row, and gzip-compressed product-analytics captures now decode to their event name and properties. 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. WHO IT'S FOR Web developers, analytics engineers, QA teams, marketing technologists, and privacy professionals who debug, audit, or validate tracking implementations.
