## What it is
A library that lets Unity developers write game scripts in native C++ (or C/assembly) instead of C#, communicating via P/Invoke bindings. It provides bindings and code generation so C++ code can act like MonoBehaviour scripts while avoiding Unity's garbage collector and IL2CPP build overhead.

## Use cases
- write unity game scripts in c++
- avoid unity garbage collector frame hitches
- speed up unity build and compile times
- use simd intrinsics in unity game code
- replace c# game logic with native plugin
- hot reload c++ code in unity editor

## When to choose
- you need deterministic performance without Unity's garbage collector
- slow IL2CPP build times are hurting iteration speed
- you want direct control over machine code, SIMD, or assembly in a Unity game

## When to avoid
- your team is C#-only and not comfortable with C++
- you rely heavily on .NET APIs, generics, or C# ecosystem tooling
- you need long-term support or frequent updates - the project has not seen releases since 2021
