Best practices for publishing Godot web games on external browser portals

Hi everyone,

I run a browser gaming website called BunaGames, and I’m interested in improving how Godot web exports behave when they are hosted or embedded on external browser game portals.

For developers who publish Godot games to the web, what are the best practices for:

  • reducing initial download size

  • improving WebAssembly/WebGL loading performance

  • responsive scaling on mobile

  • fullscreen support

  • iframe compatibility

  • audio and input focus

  • cross-origin requirements

  • performance on lower-end devices

I’m especially interested in whether you use custom HTML export templates or specific export settings when distributing games to third-party websites.

Any advice from developers who regularly publish Godot games to browser portals would be appreciated.
