## What it is
Huatuo is a native C# hot-update solution for Unity that extends the il2cpp AOT runtime into an 'AOT + Interpreter' hybrid runtime, enabling dynamic assembly loading on all platforms including iOS and consoles. It implements a high-performance register interpreter and differential hybrid DLL technology so hot-updated code runs at near-native AOT performance with zero learning cost.

## Use cases
- hot update c# code in unity games on ios without jit
- fix bugs in shipped unity game without app store review
- load c# assemblies dynamically in il2cpp builds
- run hot-updated game logic at near-native performance
- avoid lua-based scripting limitations in unity projects
- support reflection and inheritance across hot-update and AOT code

## When to choose
- you need full C# feature support (reflection, multithreading, async) in hot-update code
- you want near-zero learning cost and no adapters or code generation
- you target iOS or consoles where JIT is restricted
- performance and memory of hot-updated code matter

## When to avoid
- your project uses mono backend instead of il2cpp
- you need a simple scripting layer and can accept lua or other VM tradeoffs
- you require long-term vendor support - the project appears no longer actively maintained

## Facets
- artifact type: library
- maturity: maintenance
- function: interpreter, compiler
- domain: programming-languages, cross-platform
- platform: cpp, game-engine
- tags: unity, il2cpp, hot-update, csharp, aot-interpreter, hybrid-runtime, differential-hybrid-dll, game-hotfix, game-development, android, ios
