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.
