NoSQL Workbench for Amazon DynamoDB adds support for DynamoDB local

You can use NoSQL Workbench to build new data models easily and from scratch, or import and modify existing data models. You also can visualize data models based on your applications’ access patterns. With the addition of support for DynamoDB local, you now can develop and test your DynamoDB applications in your local development environment without incurring any additional costs. DynamoDB local does not require an internet connection and it works with your existing DynamoDB API calls.
