Mixin Watchdog is a lightweight developer utility mod that scans all active mixins at runtime and reports which mods are mixing into which classes — including cross-mod interactions.
Features:
- Detects when mods mix into classes from other mods or vanilla Minecraft
- Flags potential mixin conflicts (e.g. multiple mods targeting the same class)
- Logs mixin class names, configs, and source mods
- Outputs to both text and JSON logs in the logs/ folder
- Thread-safe logging with support for large modpacks
Designed to help mod developers, modpack creators, and server admins identify compatibility issues early — before they cause crashes.
No setup required. Just install and launch.
