Add domain to Google Appengine w/o using Google Ap

Question

I've tried to add a custom domain for my app, my own domain, instead of default example.appspot.com.

But just figured out that Google don't allow to use Google Apps for free anymore. Only Google Apps for Business.

Actually I don't need anything provided by Google Apps for Business, just need to use my own domain for my GAE project. But seems that now there no way to use custom domain w/o signin for Google Business account? and paying $50 a year.
Is it correct? Is there any other way to add custom domain to GAE?

Answer 1

From https://stackoverflow.com/a/23006209/8137:

I just discovered today (as of 2014-04-11) a new custom domain settings page is available from Google Developers Console:

1. Go to https://console.developers.google.com/project
2. Click on your project
3. On the left click "App Engine"
4. Click "Settings"

There you go! You can configure custom domain without the need of Google App account!
