Automates lots of the process you need to to setup a selfhosted instance. But you can’t self host on your own hardware, need to use a VPS which is Hetzner or DigitalOcean only.

Hello, is there a way to self host selfprivacy? I didnt find any links or docs for the vps/script/setup for a vps that isnt digital or hetzner
Not yet. We’re still working on a generic installer and will target Proxmox soon.
