This repository contains a compiled Protocol Buffer descriptor (.desc file) that allows you to decode and analyze Firebase Analytics (GA4) network requests sent from mobile apps (Android/iOS).
firebase_analytics_proto_by_luratic.desc
A compiled protobuf descriptor for decoding Firebase Analytics payloads.
This file can be used to interpret binary-encoded messages sent via gRPC, protobuf, or POST payloads in Firebase Analytics requests.
Google Analytics 4 (GA4) on mobile apps (via Firebase SDK) sends data in a binary protobuf format rather than plain JSON as in web measurement.
This descriptor helps researchers, developers, and analysts inspect and reverse-engineer those network payloads to better understand how GA4 events are structured and transmitted.
It can be used for:
- Decoding mobile analytics payloads captured with tools like Charles, Proxyman, or mitmproxy
- Debugging analytics implementations in Firebase SDKs
