ddbsh (the DynamoDB shell) is an open source CLI for DynamoDB. You can download it here. We would like to make it easier for you to install and use this tool. A pull request has been submitted to homebrew but it is currently blocked. One of the reasons for this is that the ddbsh github repository is not well enough known.
If you would like to have a homebrew formula for ddbsh, please help!
