Event Watcher

Watch analytics, GTM and consent events in real-time. 400+ 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 1.2.0 Grouped view — eight ways to slice the same session: ▪️Tool — events grouped by category and platform ▪️Page — events grouped by domain and page path ▪️Event Name — events grouped by their semantic name (page_view, purchase, …) so the same gesture across vendors lines up ▪️Consent Category — every captured event grouped by which consent it requires (Analytics / Marketing / Functional) ▪️Datalayer — dataLayer pushes grouped by where they came from (your site, a tag manager, or a third-party script) and broken down by TMS vendor or specific script ▪️Endpoint — every outbound request grouped by destination host, split first-party vs third-party so server-side / CNAME / edge collectors stand out ▪️Cookie — events that wrote a cookie, grouped first/third-party then by cookie name ▪️Identity — events grouped by canonical identifier kind (User ID / Device ID / Session ID / Pixel ID / Click ID) — surfaces mid-session ID changes and identity-stitching gaps that the stream view can't show A drag-to-reorder picker lets you pin the pivots you actually use to the chip row. Also new in 1.2.0: ▪️AI Chat for any group scope — right-click any group header to open a chat scoped to that slice ▪️Consent Platform vs. Google Consent Mode mismatch warning — better detection of when your CMP and Google Consent Mode signals disagree, so silent drift between the two surfaces in the consent timeline instead of going unnoticed ▪️31 new supported platforms across ad tech, advertising, analytics, A/B testing, customer data platforms, monitoring, video / audio streaming, widgets, and server-side data collection; 31 missing platform icons backfilled; CMP detection coverage extended to 11 more consent platforms 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) 400+ 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), and Script Tree (dependency tree of every tracking script on the page). 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.
