## What it is
KSCrash is an open-source crash reporting framework for Apple platforms (iOS, macOS, tvOS, watchOS, visionOS). It catches Mach exceptions, signals, C++/ObjC exceptions, main thread hangs, and OS-level terminations, generating full Apple-format crash reports.

## Use cases
- capture crash reports in an iOS app
- detect main thread hangs in Swift apps
- report OOM and thermal terminations on Apple platforms
- collect Objective-C and C++ exception backtraces
- send crash reports to a custom backend server
- debug app crashes on tvOS and watchOS

## When to choose
- you need self-hosted or custom crash reporting on Apple platforms
- you want full Apple-format crash reports with every field filled in
- you need hang detection and termination diagnostics beyond what Xcode gives
- you want an MIT-licensed, dependency-light crash reporter

## When to avoid
- you want a turnkey hosted dashboard with symbolication and analytics out of the box (use Sentry or Firebase Crashlytics)
- your app targets non-Apple platforms
- you only need basic analytics events rather than crash diagnostics

## Facets
- artifact type: library
- maturity: active
- function: monitoring, logging, developer-tools
- domain: mobile-development, developer-tools, apple-ecosystem
- platform: cpp
