Hi,
In the Mendix Free (Cloud Node) version, you cannot have multiple parallel environments (like Dev/Test/Acceptance) within the same app. Each app is limited to a single free environment.
However, your proposed approach is valid.
You can create a separate app as a sandbox:
.mpkThis effectively gives you a second parallel environment, just as a separate app.
If you don’t want a separate app:
But this is not fully isolated like a real environment.
You cannot have multiple environments within a single free app, but creating a duplicate app as a sandbox is the correct and commonly used workaround in the Free version.
As far as I know, mendix does not allow to have multiple envs on a free sandbox.
Instead, you can create different braches to your app and you can make changes to mainline and your collegagues can make to another branch.
Only one person at a time can utilize Sandbox, but your code wont be distrubed.
LAter point in time, if everything is working fine you can merge all the braches to mainline and have a single source code.
