Why JEngine

Ultralight Core

A handful of files — that's the entire core package. Drop it in and hot updates just work. No boilerplate code required.

10x+ Performance

HybridCLR runs standard C# natively — 10x+ faster than ILRuntime or Lua. UniTask for GC-free async, Nino for zero-allocation serialization.

Built-in Security

Encrypt assets and DLLs with XOR, AES, or ChaCha20. Obfuscate hot update code with Obfuz. No other hot update framework ships this.

One-Click Build

Compile code, generate AOT metadata, obfuscate, encrypt, and package resources — all from one button in the JEngine Panel.

All Platforms

iOS, Android, Windows, macOS, WebGL — plus WeChat, Douyin, Alipay, and TapTap mini-game platforms. YooAsset powers games with 1M+ DAU.

AI-Powered Development

First hot update framework with a Claude Code plugin. AI that understands JEngine patterns and writes idiomatic code for your game.

Before & After

Traditional Approach	With JEngine
Learn Lua or TypeScript for hot update code	Standard C# — same language, same IDE, same debugging
Register cross-domain adapters (ILRuntime)	Zero adapters — HybridCLR runs C# natively
No built-in asset protection	XOR / AES / ChaCha20 encryption + code obfuscation
Manual multi-step build pipeline	One-click build from JEngine Panel

Quick Start

Unity 2022.3+ required. Follow the Getting Started Guide to be up and running in minutes.
