Ship game updates without shipping a build.
Runtime hot updates for all platforms — push code, assets, and logic without rebuilding.
Powered by HybridCLR with built-in encryption and obfuscation.
1,000+ games shipped · 100+ companies in production · built-in Claude Code AI integration.
Why JEngine
Ultralight CoreA handful of files — that's the entire core package. Drop it in and hot updates just work. No boilerplate code required. |
10x+ PerformanceHybridCLR runs standard C# natively — 10x+ faster than ILRuntime or Lua. UniTask for GC-free async, Nino for zero-allocation serialization. |
Built-in SecurityEncrypt assets and DLLs with XOR, AES, or ChaCha20. Obfuscate hot update code with Obfuz. No other hot update framework ships this. |
One-Click BuildCompile code, generate AOT metadata, obfuscate, encrypt, and package resources — all from one button in the JEngine Panel. |
All PlatformsiOS, Android, Windows, macOS, WebGL — plus WeChat, Douyin, Alipay, and TapTap mini-game platforms. YooAsset powers games with 1M+ DAU. |
AI-Powered DevelopmentFirst 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
