    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.
    
    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.
    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.

    description
    See every tracking event on your website in real-time.
    
    One DevTools panel replaces the need to switch between multiple vendor-specific debuggers.
    
    WHAT IT DOES
    
    Event Watcher captures four types of tracking activity as it happens:
    
     - Network Tracking Requests: HTTP requests sent to analytics, advertising, and marketing endpoints
     - DataLayer Pushes: Events pushed to data layers across multiple implementations
     - Script Loads: Tracking scripts loading on the page, with full initiator chain showing how each script was loaded
     - Navigation Events: Page URL changes via History API, popstate, and hash changes
    
    BROAD PLATFORM COVERAGE
    
    Detects 400+ tracking platforms across 14 categories including analytics, tag managers, advertising, customer data platforms, consent management, session replay, ad tech, A/B testing, and marketing automation.
    
    Each detected platform is shown with its official icon, brand color, and category badge for quick visual identification.
    
    FOUR VIEW MODES
    
     - Stream View: Chronological event stream with platform icons, timestamps, and contextual badges
     - Tool View: Events grouped by category and platform
     - Page View: Events grouped by domain and page URL
     - Script Tree View: Dependency tree showing which scripts loaded which
    
    DEEP EVENT INSPECTION
    
    Click any event to inspect its full payload: parsed parameters in human-readable tables, custom data (event properties, user properties, traits), e-commerce data, consent signals, cookies set, raw request details, and script dependencies.
    
    35+ platforms have dedicated parsers that transform raw request payloads into structured, readable output with labeled sections and grouped parameters.
    
    SCRIPT INITIATOR TRACKING
    
    Every script and request is classified by how it was loaded: directly by the page, by a tag manager, or by another third-party script. Uses stack trace analysis to build a complete dependency tree of all tracking tools on the page.
    
    CONSENT STATE TRACKING
    
     - Detects 40+ consent management platforms and reads consent state from cookies, browser APIs, and data layer events
     - Tracks consent mode parameters across major analytics tags
     - Shows a consent timeline: initial defaults, consent platform loading, user choices, and updates
     - Highlights potential compliance issues such as tracking before consent or after denial
    
    TAG MANAGER HUB & CONTAINER INTERCEPT
    
     - Container intelligence: version info, tag/variable/trigger counts, and script dependencies
     - Container actions: block, swap, or preview tag manager containers for debugging
     - Rules persist across page reloads
    
    SEARCH & FILTERING
    
    Keyword search, platform filter, category filter, script filter, consent filter, interaction filter, and saveable filter presets. Filter combinations let you isolate exactly the events you need.
    
    COPY & EXPORT
    
     - Copy individual events as JSON or tab-separated table
     - Export the full event stream as HAR
     - Export consent timeline as JSON
    
    CUSTOMIZABLE
    
    Configurable defaults for stream direction, sort order, filter states, and data layer nesting. Add custom tracking endpoints for internal or uncommon platforms. Resizable panels, keyboard navigation, and a sun/moon dark mode toggle synced across DevTools and the side panel.
    
    MULTIPLE ACCESS POINTS
    
    Use it as a DevTools panel (primary), Chrome side panel, toolbar badge showing active tool count, or popup for a quick overview.
    
    WHO IS THIS FOR?
    
    Built for web developers, analytics engineers, QA teams, marketing technologists, and privacy/compliance professionals who need to debug, audit, or validate tracking implementations.
    
    PRIVACY
    
     - All captured data stays local and in-memory only
     - No browsing data, URLs, or page content is sent to external servers
     - Optional anonymous usage analytics to help improve the extension (opt-out available in Settings)
     - No personally identifiable information is collected

About

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.

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.
