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 1.3.0 Two new view modes — Pinned and Stack: ▪️Pinned — a per-domain parking spot for events. Hover any row in Stream and click the pushpin to save it. Pinned events survive Clear and inspected-page reloads, so you no longer need to export and re-import just to revisit a handful of events. ▪️Stack — the site's martech stack as a tree. One node per platform, parented by who loaded it: page → tag manager → vendor tools. Each card carries an attribution dot (green / yellow / grey) showing how confident the parent assignment is, and clicks open a per-tool detail panel with Stack position, Session activity, and Consent context. Exports as Markdown, Mermaid (flowchart LR), SVG, or a one-click drop into MartechStack Builder. Also new in 1.3.0: ▪️Consent violations on tool chips — every filter-toolbar chip's count badge now reads as neutral metadata, with a red or yellow pill alongside showing the actual count of denied or pre-consent events that tool fired. You can see which tool is the consent offender at a glance, not just that a violation exists somewhere in the session. ▪️Export menu overhaul — the same five formats wherever you copy events. "Copy for Human" gives a readable, curated JSON view. "Copy for AI" is a sparse, single-letter-key payload tuned to fit the input limits of popular AI tools. "Copy Complete" is everything including raw HTTP and the consent timeline. "Copy Full DataLayer" gives only dataLayer pushes plus computed state. A new "AI tool target" setting picks the paste-size budget so the AI copy auto-trims for ChatGPT Free / Plus / Claude / Claude Enterprise. ▪️Display density — a Compact mode in Settings tightens padding across the toolbar, event list, and detail panel so more fits on screen. Font size is unchanged; use browser zoom for that. ▪️Settings modal redesign — a search bar at the top of Settings, a new Look & Feel section for visual-presentation toggles (theme, toolbar layout, tool chips, density), and refreshed descriptions across the modal. ▪️Sharper detection — Stape Data Tag client beacons on first-party analytics subdomains are now caught by the existing detection gate, Tealium Collect events split tracked-payload from session-storage passthroughs in exports, and CDP destination configs (Segment, RudderStack, Hightouch, mParticle, Adobe AEP Web SDK, Adobe Launch) now render a clickable "Destinations configured" section. ▪️New supported platforms across tag managers, analytics, CDPs, first-party collection, and widgets. 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.
