I thought it best to explain the state of Cocos products, as it seems a number of similar questions have arisen lately.
Cocos2d-x: v3 continues to receive bug fixes and important updates. v3.18 is planned in the future. v4 will bring Metal support with some other bug squashing. Going forward v4 will most likely be the main branch, replacing v3. Time will help us decide this. There is no visual editor for Cocos2d-x.
Cocos2d-lua: is stable and fast.
Cocos2d-x-lite: is a derivation of Cocos2d-x that provides a runtime environment for Cocos Creator. It is not possible to use Cocos2d-x-lite for game creation.
creator_to_cocos2d-x: is an EOL’d Cocos Creator plugin for exporting the UI of Scenes to c++ source files. This plugin currently only works with Cocos Creator v1.9.3.
Cocos Studio: an EOL’d GUI editor for Cocos2d-x. It is NOT open source and there are no plans to do this for the foreseeable future.
Cocos IDE - an EOL’d IDE environment.
Cocos GUI: an EOL’d project management tool that let you manage Cocos projects.
