Event Watcher

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 1.1.0

Optional AI assistance, powered by your own API key:

▪️Event Explainer — one click explains what any captured event is, what it's doing, and whether it looks right
▪️AI Chat — ask free-form questions about your captured session (consent flow, duplicate events, missing data)
▪️Smart Unknown Identification — identifies unknown tracking endpoints the built-in detection can't classify
▪️Page-scoped and container-scoped AI — focused presets for analysing a single page navigation or a GTM container's tags, variables, and triggers
▪️Bring your own key from Google Gemini (free tier available), Anthropic Claude, or OpenAI. Keys are stored locally in the browser. AI features are fully optional and disabled by default; PII redaction in prompts is on by default.

Also new in 1.1.0:

▪️Event Comments — attach a free-text note to any captured event ("missing currency", "fires twice on mobile"); notes travel with JSON exports and are picked up by AI features automatically
▪️Settings → Features — hide whole feature areas (AI, GTM Hub, Script Tree, Cookie detection, Consent Check) to match how you actually use the extension

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.

FOUR VIEW MODES

Stream (chronological), Tool (grouped by category), Page (grouped by URL), 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.

WHO IT'S FOR

Web developers, analytics engineers, QA teams, marketing technologists, and privacy professionals who debug, audit, or validate tracking implementations.

PRIVACY

▪️Captured data stays local and in-memory by default — no browsing data, URLs, or page content is sent anywhere
▪️AI features are opt-in and only send data to the AI provider you configure with your own API key
▪️Anonymous usage analytics are optional and can be disabled in Settings
▪️No personally identifiable information is collected by the extension itself

Free. No premium tiers, no feature gates, no account required.
