  💡 Why Choose Felix Debugger?
  
  Felix Debugger is more than just a Chrome extension, it’s a complete GA4 debugging and analytics QA tool. Instead of switching between tools or manually decoding requests, you get:
  ✅ Faster debugging
  ✅ Better data quality
  ✅ Clear insights into GA4 tracking

  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 :)!
