It needs to run on a machine that can handle it. Uploading to your website is not an option. It is basicly a game. So you need to treat it as a game.
You can alternatively use “Pixel Streaming” to run it on a server and then integrate a page on your website and stream it to that website. Like a netflix stream or similar. So the website only displays what is happening on the streaming server. This way you can play it on a phone or in any web browser. Look it up, there is documentation for it.
