Netlify is our preferred hosting platform due to its ease of use and getting started. They have a drag and drop interface that allows you to take your Deployment output and get started.
The Gorilla App Deployment instructions prominently feature:
The Drop experience will ask you to create an account after upload. I suggest you do that so you can further manage the app later.
Go to Site settings → General → Site details and click "Change site name". Choose something memorable like familyname-gorilla.
Go to Site settings → Domain management → Custom domains. Click "Add custom domain" and follow the instructions to connect your own domain (e.g., example.com).
The easiest way to update your Gorilla site is to use the app to "Add More Videos" and then redeploy. Once you do it once, it should be pretty quick, as all the configuration will be saved.
Keep an eye on your usage to stay within free tier limits:
View your usage in Team settings → Usage.
Share your Netlify URL with your children and enjoy your custom YouTube content!
