KBEngine 是一款開源的游戲辦事端引擎，應用簡略的商定協定就可以夠使客戶端與辦事端停止交互，
應用KBEngine插件可以或許疾速與(Unity3D, OGRE, Cocos2d, HTML5, 等等)技巧聯合構成一個完全的客戶端。

辦事端底層框架應用c++編寫，游戲邏輯層應用Python(支撐熱更新)，開辟者無需反復的完成一些游戲辦事端通用的底層技巧，
將精神真正集中到游戲開辟層面下去，疾速的打造各類收集游戲。

(常常被問到承載下限，kbengine底層架構被設計為多過程散布式靜態負載平衡計劃，
實際上只須要赓續擴大硬件就可以夠赓續增長承載下限，單台機械的承載下限取決於游戲邏輯自己的龐雜度。)
