Stack Deobfuscator Mod (1.20.4, 1.19.4) | 1Minecraft

Stack Deobfuscator Mod is a lifesaver for mod developers. Instead of staring at useless error messages full of obfuscated class names like net.minecraft.class_310, you get real readable output like net.minecraft.client.MinecraftClient. Every crash report and console error gets automatically remapped so you can actually figure out what went wrong.

Why Use Stack Deobfuscator?

When something breaks in Minecraft with mods, the crash logs are almost impossible to read in production builds. This mod fixes that instantly. All those random class names and method calls suddenly become actual class names you recognize. No more guessing where the error actually happened.

Before and After

The difference is night and day. Here’s what you get without it:

net.minecraft.class_148: Manually triggered debug crash
at net.minecraft.class_309.method_1474(class_309.java:509)
at net.minecraft.class_310.method_1574(class_310.java:1955)

And here’s what Stack Deobfuscator gives you:

net.minecraft.util.crash.CrashException: Manually triggered debug crash
at net.minecraft.client.Keyboard.pollDebugCrash(Keyboard.java:509)
at net.minecraft.client.MinecraftClient.tick(MinecraftClient.java:1955)

The mod works with Yarn/Quilt mappings and Mojang mappings, so you get readable output no matter what.
