Godot and Netlify

Quickly deploying Godot games on the web with Netlify

January 22, 2023

When I think of video games, I generally still think of an application that is downloaded and runs on the client. Technically, that’s still the case with web-based exports from Godot Engine, since the web browser has to download the files before being able to run them.

I thought maybe I could just run the index.html file locally, but that does not work, as the web-based games with Godot Engine rely on modern browser features that require specific opt-in settings from the web server. If you try to just run the “index.html” file directly, you’ll be greeted with the following type of message instead of the game:

Hosting with Netlify is super simple. Create a new manual deployment, create a zip from the exported files, and upload it. It’ll show the same error message until Netlify is configured to allow the required features. Simply add a netlify.toml configuration file with the following contents:

# netlify.toml
[[headers]]
  for = "/*"
  [headers.values]
    Access-Control-Allow-Origin = "*"
    Cross-Origin-Opener-Policy = "same-origin"
    Cross-Origin-Embedder-Policy = "require-corp"

That’s all it took for a Godot Engine web export to come to life.
