JEngine — Development skill for Claude Code

**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 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.
