Exactly what apps are you looking to install? Cloudways is just a managed Vultr, their panel gives you one click installs.
NextCloud, OSTicket. There might be 1 or 2 other similar apps.
Yeah, don't know anyone but Softaculous that will do those. I mean, you can use MY install guides. They are about as easy I've got specifically guides for both of those. One is already a Salt state file, so you just "apply" it and you are good to go. The other one I am working on.
