Can Objectify be used outside of GAE?
2 answers
Objectify is for GAE use only. Other Java ORMs that can interoperate with the Datastore like JDO, JPA, etc. are similar.
To access your data store from the outside world, you will either want to write handlers in your GAE API that can use the Datastore interface for you, simply by pushing those methods on your API that make sense in the context of your application, or you will use the Google Cloud Datastore API Client Library for Java , allowing an external application to directly touch your data store.
