What KSCrash is

KSCrash is a free, MIT-licensed crash reporting framework for iOS and macOS apps. After it is installed, it saves reports on disk and can capture Mach exceptions, signals, C++ and Objective-C exceptions, main-thread hangs, and operating-system events such as out-of-memory, thermal, CPU, and reboot terminations. Reports use Apple’s format. The project documents installation with Swift Package Manager or CocoaPods.

Its Watchdog monitor flags main-thread hangs lasting 250 milliseconds or longer and records full backtraces. CPU monitoring follows averages over sliding windows and can create non-fatal reports when warning or critical states occur. Other capabilities include a sampling profiler, zombie detection, memory tracking, automatic crash-cause diagnosis, and custom exception reporting. KSCrash also processes MetricKit MXCrashDiagnostic payloads; that integration does not yet support hang and CPU exception diagnostics. For server delivery, the project directs users to use a KSCrash installation. Its security policy cautions that reports may contain sensitive information and recommends reviewing them before transmission and using HTTPS endpoints.

Who it suits

KSCrash suits developers building for Apple platforms who want an open-source framework to capture and store crash reports. It may also fit teams that need hang monitoring, CPU monitoring, or MetricKit processing as part of their crash reporting setup.

What it does well

  • Free, MIT-licensed framework.
  • Supports iOS and macOS.
  • Captures multiple exception types and operating-system terminations.
  • Hang monitoring records full backtraces for hangs of 250ms or more.
  • Offers CPU monitoring, memory tracking, and a sampling profiler.
  • Installation is documented for Swift Package Manager and CocoaPods.

What to know first

  • MetricKit integration does not support hang and CPU exception diagnostics.
  • Server delivery requires a KSCrash installation.
  • Crash reports may contain sensitive information that needs review before transmission.

As github.com lists them, read 4 Oct 2026. The maker's own page has the final word.

Getting started

  1. Open the KSCrash project website.
  2. Choose Swift Package Manager or CocoaPods for installation.
  3. Install KSCrash in the Apple platform project.
  4. Review reports before transmission and use an HTTPS endpoint when sending them to a server.

Verdict

Choose KSCrash if you need a free, open-source crash reporting framework for iOS or macOS with on-disk Apple-format reports and broad crash capture. Look elsewhere if your MetricKit workflow depends on hang or CPU exception diagnostics, or if you need server delivery without a KSCrash installation.
