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
