About this Mod

🤪 Insanity Wrapper

Because if you want it to work right, you need to wrap it up!

Run Fabric & Quilt mods on NeoForge for Minecraft 1.21.11+! Insanity Wrapper is a powerful compatibility layer that bridges different modding frameworks into a unified NeoForge environment.


🎯 What Does It Do?

Ever wanted to use your favorite Fabric mods alongside NeoForge? Insanity Wrapper makes it possible. Simply drop it in your mods folder along with any compatible Fabric/Quilt mods, and watch the magic happen!

No complicated setup. No manual conversions. Just download, install, and play.


🏗️ Core Components

Insanity Wrapper is built on three powerful systems working together:

Insanity Loader

A custom mod loader built on NeoForge that extends modding capabilities beyond what NeoForge provides out of the box. It implements Fabric Loader API shims, handles mod discovery, and manages the entire compatibility pipeline.

Fabric API Shims

Custom-built compatibility layers that route Fabric API calls to their NeoForge equivalents. These are not the actual Fabric API—they're manually crafted implementations that provide the same interface.

Insanity Transformer

Handles bytecode transformation, import remapping, and compatibility patching to ensure seamless integration between modding ecosystems.


✨ Key Features

  • Full Mixin Support — NeoForge's native Mixin system handles everything
  • Access Widener Conversion — Automatically converts to Access Transformers at runtime
  • Cross-Mod Compatibility — Fabric mods can interact with NeoForge mods via the event bus
  • Network Translation — Seamless packet conversion between Fabric and NeoForge
  • Simple Installation — Just drop it in your mods folder!

Frequently Asked Questions

Insanity Wrapper server crashes on startup – what to do?

Most common cause: wrong neoforge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.

Is Insanity Wrapper compatible with neoforge?

Insanity Wrapper officially supports neoforge for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Insanity Wrapper – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Insanity Wrapper consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
