Hi,
I would like to know if there is any sandbox environment in Squidex Cloud.
I developed a marketplace that is running in production, but I need a sandbox mode to test new features and fix bugs.
Thanks.
You can just create a second app for free 
Ok, but how can I replicate some Schemas and Content from my Production App?
You can use the CLI for that: https://docs.squidex.io/02-documentation/developer-guides/automation-tools#synchronize-all-app-settings
