![](/files/-M2ys_54msQxGBitP7PS)

官方說明：

> ConfigCat is a feature flag and configuration management service. Providing a nice user interface where you can change the configuration of your application on the fly.

Global config setting在我工作上很常用到，主要的目的是：**希望不需透過更改Code，來控制一些參數**。

比如說：

你的主管想要測試網站字體大小，你可以把這個自體大小設定儲存在Config cat上，這樣你只要給你的主管Config cat網站，他就能夠很快的自己做字體調整，你就不用重新部署你的網站了。
