Real-time GA4 debugging for Analysts and Developers. Decode, validate and inspect Google Analytics 4 requests. GA4 debugging belongs in DevTools. Not in the network tab, not in an external tool, not in a spreadsheet you built yourself to decode request strings. Felix puts everything directly inside Chrome, where the work actually happens. Every GA4 request gets captured the moment it fires. Over 70 parameters decoded automatically, translated from raw tracking data into something a human can actually read. No setup, no switching contexts, no manual inspection. You open DevTools, you see your data. From there, a chronological event timeline shows you the full sequence of user interactions so you can follow exactly what happened and when. If something does not add up between two events, the side-by-side comparison view shows you where they diverge. E-commerce arrays, which are usually unreadable in the network panel, become a clean table with product names, IDs, prices, quantities and categories laid out clearly. Consent Mode signals are decoded into a visual dashboard so you know exactly which storage types are active at any point. Felix also validates every event automatically against GA4 360 limits or GA4 Basic (you can switch via settings) and best practices. Missing parameters, reserved event names, incorrect setups, all of it flagged in real time before bad data reaches your reports. For complex implementations, keyword and regex filtering lets you find exactly what you are looking for. And when you need to share findings or document a session, one click exports everything as structured JSON. Page performance sits alongside your analytics data too. TTFB, First Contentful Paint, DOM Complete, and a visual waterfall chart, because tracking and performance rarely live in isolation. Everything runs locally in your browser. No external servers, no accounts, no data collection of any kind. Your data stays yours. Built for Digital Analysts, Frontend Developers, and QA Engineers who need accurate GA4 data and do not have time to chase it down. Please share your feedback and wishes with us to max. the value for our analytics community :)!
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. 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. ▪️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. ▪️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. 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). 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. ▪️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 Container intelligence (versions, tag/variable/trigger counts, dependencies) and container actions — block, swap, or preview — with rules that persist across reloads. 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. Configurable defaults, custom tracking endpoints for internal or niche platforms, resizable panels, keyboard navigation, and dark mode that follows your DevTools theme. 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. ▪️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

New Window to the Right
Opens a new window directly to the right of the current window and wraps when the window reaches the edge of the monitor. # New Window to the Right A Chrome extension to avoid having new window open off screen or partially off screen. This Chrome extension opens new windows directly to the right of the current window (instead of Chrome's default cascading behavior). Like many people, my Chrome window is always set to take the maximum vertical space on my monitor (but not the maximum horizontal space). Unfortunately, whenever you open a new Chrome window, Chrome cascades new windows down and to the right by default. This means that every new window starts off with part of its window off screen. 1. **Disables cascading:** Opens new windows directly to the right of the current window. 2. **Right edge protection:** Protects against opening a new window having any part of its window off screen to the right. If a new window has any portion of its window off screen, the new window will open on the left side of the screen, instead. 3. **Multi-monitor support:** New windows always fully appear on the same monitor from the window they were spawned from. (Note: The source monitor is determined by the location of the top left corner of the last focused window.) This keeps windows from opening with their window split across multiple monitors or having a window appear on a different monitor than the one you were originally working on (less mental context switching). * Note: The source monitor is determined by the location of the top left corner of the last focused window. I hope you find this as useful as I have!
