FAQ: Stacktrace Cleaner
Can Stacktrace Cleaner deminify stack traces automatically?
It improves readability, but full deminification still requires matching source maps.
Why should I focus on the first app frame?
That frame often marks the closest userland boundary where the failure actually started.
Is cleaned stack output useful for postmortems?
Yes. Cleaner traces improve cross-team communication and reduce ambiguity in incident reviews.
