Why JEngine?

• Lightweight - Only core package (few files) required; add optional packages as needed
• One-Click Build - JEngine Panel builds code + assets with obfuscation in one click
• 10x+ Performance - HybridCLR outperforms ILRuntime/Lua hot update solutions
• Zero/Minimal GC - UniTask (GC-free async) + Nino (high-performance serialization)
• All Platforms - iOS, Android, Windows, macOS, WebGL, WeChat, Douyin, Alipay, TapTap
• Secure Updates - Obfuscate hot update DLL + encrypt resources (assets & DLL/PDB) with XOR/AES/ChaCha20
• Commercial Ready - Production-proven by individuals and enterprise teams
