Isn't that one of the many, manyavailable Laravel Forge CLI tools?
So, yeah - Forge CLI is a CLI tool to interact with your Laravel Forge provisioned server and site.
This allows you to keep a single YML file that contains the configuration of both your staging and your production server.
With Forge CLI, you can simply pull down the current environment file from Forge, edit it in your favorite code editor, and push the changes back to Forge.
But Forge CLI also allows you to synchronize the changes that you make to this file, back to Forge.
