Sorry I missed your comment. I have Kuma on the VPS because it’s monitoring my two other sites. Basically if I’m out of town and power is out, I’ll know, and still be able to access my vaultwarden. Everything else is hosted locally

I can’t speak to cosmos, but I have Pangolin, Kuma, and vaultwarden on a hetzner vps and I love it. I run everything in docker compose files on a Debian host. Right now I have authentik on one of my sites, but I think I will be switching to voidauth also hosted on the vps in the near future

Is this kind of a nextcloud / office365 replacement?

I set up a piefed instance pretty easily for personal use, I recommend checking it out
