I think this is more where you run a kiosk and you can (using cli) deploy an instance of a selection of apps per domain. Its all Opensource.

elfhost seems to be a commercial service to sell you deployment of SaaS hosted aps. ( But it looks like to bundles deployment and hosting - Im not sure)

What I am trying to understand is whether coopcloud are trying to bring those apps together to work in standard integrated ways - Or just be able to spin them up.

e.g. Having out of the box ldap, email and Nextcloud instances that work nicely together would be appealing. Drop a domain in. Spin up an instance and you are off.
