Is it possible to create different project folder for each tenant/customer?

Is it possible to create a different project folder for each tenant/customer?

If yes, how do I create?
Can anyone help me out with this?
Projects : Node-RED

No you cannot. Node-RED is not a multi-tenant runtime. You can have multiple users, but they all access the same set of flows/project.

You can run multiple instances of node red on different ports, if that would solve your problem.
