Drengr vs Firebase Analytics
Firebase logs the events you instrument with logEvent(). It never sees the HTTP response your app received — so it can't tell you a checkout returned `insufficient_funds`. Drengr captures the response in-process and annotates it into a business event server-side, with zero tracking code.
| Capability | Drengr | Firebase Analytics |
|---|---|---|
| Sees network response bodies | ||
| Business events 0-code (payment outcome, decline reason) | ||
| Tells you WHY a payment failed | ||
| Manual event instrumentation | Not needed | Required (logEvent) |
| Mobile-first |
