Is it possible to use google datastore without app engine?

Question

Is there a "disable app engine only" button so I don't have a rogue hello world application hanging around on the web?

When I use this button it disables everything including datastore which I use separately as my haskell app database.

Answer 1

No, you cannot disable your App Engine and still have Datastore working.

That being said, you only need App Engine enabled, you don't need to have a functioning app or even a deployed app.
