Can you delete appengine projects?

I just hit my 10 application limit. Is there a way to delete ones where I never finished the idea?

Can you delete a Google Cloud project?

In the Google Cloud console, go to the IAM & Admin Settings page. On the IAM & Admin Settings page, click Select a project. Select the project you want to delete, and click Open. Click Shut down.

No, you can't delete apps. You can reuse them, particularly if you intend to use a custom domain anyway, or you can post a request on the official group and one of us Googlers will grant you extra apps. We'd prefer you didn't create a new account.

App deletion is now supported - just click on 'Application settings' under 'Administration' in your control panel, and click 'delete application'.
