## What it is
MelonLoader is a universal mod loader for Unity games that supports both Il2Cpp and Mono backends. It loads mods and plugins into games at runtime, providing a common framework for the Unity modding community.

## Use cases
- load mods into Unity games
- create mods for Il2Cpp Unity games
- create mods for Mono Unity games
- inject plugins into a game at runtime
- set up a modding framework for a Unity title
- debug game mods during development

## When to choose
- you want to mod a Unity game regardless of scripting backend
- you need one loader that works with both Il2Cpp and Mono
- you want a mature, widely-adopted Unity modding ecosystem

## When to avoid
- the target game is not built with Unity
- you need a mod loader for a non-DotNet runtime like native C++ games
- you only want cosmetic asset swaps that a simpler tool handles

## Facets
- artifact type: framework
- maturity: active
- function: plugin-system, developer-tools
- domain: gaming-tools, developer-tools
- platform: windows, dotnet, cross-platform
- tags: mod-loader, unity, il2cpp, mono, modding, game-mods, game-development, linux, macos
