Cocos2d-x vs PlayCanvas

Cocos2d-x is a free, open-source C++ framework for building games, apps, and other interactive GUI programs. Developers can publish from one codebase to mobile, desktop, web, and console targets, using C++ or JavaScript and Lua bindings. The product page lists OpenGL ES 2.0 and Metal for graphics rendering and says Lua or JavaScript can be used for game hot updates. Its maker describes the C++ core as lightweight and optimized for devices including low-end Android systems. The community maintains the framework under the MIT license. The download page says version 4.0 uses CMake for all platforms, supports Metal on iOS and macOS, and removes the H5 engine and JSB.
