StackDeobfuscator

This utility mod is designed to simplify the workflow for Minecraft mod developers by automatically converting unreadable technical class and method names into human-readable names across all error messages and crash reports.

Core Features

StackDeobfuscator performs remapping of incomprehensible production names (such as net.minecraft.class_310) into readable mapped names (such as net.minecraft.client.MinecraftClient). The functionality enables developers to instantly understand issue root causes in non-development game versions without requiring time to decrypt exception code.
