Crash Beautifier
Crash Beautifier is a focused DebugTools mini-product for developers. Clean up and inspect stack traces from mobile and web runtimes.
Use cases
- Turn pasted failures into a cleaner root-cause checklist.
- Separate the first error from retries, noise, and downstream symptoms.
- Prepare a concise report for an issue, pull request, or incident note.
How it works
- Paste or load the snippet you want to inspect in Crash Beautifier.
- Run the tool in the browser and review the highlighted output.
- Copy, export, or turn the result into the next debugging step.
Privacy
- Crash Beautifier is local-first. The core workflow runs in your browser and does not require sending pasted content to DebugTools servers.
