App Engine Starter and Enterprise versions

App Engine Starter is included in all products (that is, it's free). To access additional features outside of App Engine Starter, you need a paid App Engine Enterprise license.

The App Engine Enterprise version enables users to act as a Fulfiller for unlimited custom apps and unlimited custom tables. Customer entitlements may vary depending on the type of App Engine subscription purchased. Contact your account team or your company's ServiceNow admin for entitlement confirmation.

See App Engine: What you get on the ServiceNow product site for details on what products are included in each version.
