Decode a stack trace

A crash report from an obfuscated build shows renamed symbols. Paste the rename map that came with your Pro download and the stack trace, and get your original names back. Everything happens in this request — nothing is stored.

How it works

  • The map is the .map.txt file bundled in your obfuscated .zip when you tick Include rename map. It is a Pro feature and is never stored on our servers.
  • Any frame whose names are in the map is rewritten back to the original type and method; frames the map does not cover are left unchanged.
  • Keep the map private — it is exactly what undoes the renaming. Prefer decoding locally for sensitive traces; this page keeps nothing, but the map still crosses the network when you paste it here.
