OkHttp interceptors for network monitoring9 min readSentry does far more, including tracing, session replay, profiling and self-hosting. Codeskop is a narrower mobile tool built around crashes, ANRs and failed API calls. Here's an honest comparison with dated pricing.
Keep Crashlytics for free, mature crash reporting. Add Codeskop when you need failed API calls, ANRs on older Android versions, web errors and WhatsApp alerts in one place. Here's the honest comparison.
Flutter routes errors through three channels: the framework, the platform dispatcher and isolates. Here's what each catches, a complete main() setup, and how to report them in production.
Kotlin exceptions on iOS terminate the app with a stack trace that points at Swift, not your Kotlin code. Here's why, how to fix it with @Throws and exception hooks, and the tools that do it for you.
Use an application interceptor to record failures, an EventListener for timings, and keep HttpLoggingInterceptor out of release builds. Here's the code, plus how to ship it safely.
Firebase Crashlytics is the cheapest: it's free. Beyond that, entry plans run from $9 to $80 a month and are limited by events, users or sessions. Here's every price, checked and sourced, with picks by situation.
