    Hippy

    Hippy

    Tool to build cross-platform and high-performance awesome apps

    Hippy is a cross-platform development framework, aiming to help developers write once, run on three platforms(iOS, Android and Web). Hippy is quite friendly to Web developers, especially who are familiar with React or Vue. With Hippy, developers are able to create the cross platform app easily. Hippy is now applied in 27+ Tencent apps such as Mobile QQ, Mobile QQ Browser, Tencent Video App, QQ Music App, Tencent News, reaching hundreds of millions of ordinary users. For Android, we recommend using the real cellphone for better develop experience, because Hippy is using X5 JS engine which can't support x86 simulator, as well as ARM simulator has a low performance. For iOS, we recommend to use iOS simulator when first try. However, you can change the Xcode configuration to install the app to iPhone if you are an iOS expert.
