Make sense of your crash reports
Unmangle turns raw, mangled crash files from any Apple platform into clean, readable stack traces, right on your Mac and completely private.
Free on the Mac App Store.
Automatic dSYM matching
Point Unmangle at your symbol files and it pairs each crash with the right dSYM by UUID, so you spend time reading the trace, not hunting for the matching build.
- Matches by build UUID
- Drag-and-drop symbols
- Clear warnings when symbols are missing
See the whole crash, not just the stack
Beyond the backtrace, Unmangle surfaces the device, process, exception, and register state, and lets you jump between threads, so you can understand exactly what happened.
- Device, process & exception details
- Register state at the crash
- Navigate every thread
Symbolication powered by Apple's own tools
Unmangle symbolicates and demangles with the same tooling Apple ships in the developer toolchain, so the traces you read match what Xcode would produce. No guesswork, no third-party reimplementation of the format.
Your crash data never leaves your Mac
Everything happens locally and offline. There is no account, no upload, and no telemetry. Your reports and symbol files stay on your device, always.
- 100% on-device processing
- Works fully offline
- No account, no tracking
Automate it with the bundled CLI
Unmangle ships with unmangle-cli, a command-line tool for inspecting and symbolicating crash reports right from the terminal. Handy for when you'd rather stay in your shell than reach for the app.
- Inspect reports as structured JSON
- Symbolicate against your local dSYMs
- The same engine as the app
