Hi @ursboller
In our current release, each Firefly app can only be deployed and accessed within the same organization. While we have considered the ISV angle (where an ISV can build and sell an app / a service to be used by multiple orgs), we currently don't have a timeline for supporting this ootb.
If you have immediate need to use the same app for a few different orgs, you can potentially deploy the same code into different organizations using different credentials. However, you will need to manually manage this process as of now.
Hope this helps!
Sarah
