Autonomous Database for Developers is available on Autonomous Database on Dedicated Exadata Infrastructure

Customers who have subscribed to Autonomous Database on either Dedicated Exadata Infrastructure or Exadata Cloud@Customer can create and use Autonomous Database for Developers instances. Autonomous Database for Developers instances are free Autonomous Databases that developers can use to build and test new applications.

With Autonomous Database for Developers instances, you can try new Autonomous Database features for free and apply them to ongoing or new development projects. Developer database comes with limited resources and is, therefore, not suitable for large-scale testing and production deployments. When you need more compute or storage resources, you can transition to a paid database licensing by cloning your developer database into a regular Autonomous Database.
