Roughly speaking, due to browser security concerns, WebGL games must be executed through a web server. Running your project locally will result in the game not loading! Hosting your own server or changing your browser's settings can be tedious for yourself and others that you plan to share it with.
With that, the best way to share WebGL games is to upload it online and share it privately or publicly.
