Check out Kavita! It sounds perfect for what you’re doing and I have had literally 0 issues using all of their built-in features. It’s a surprisingly stable and full-fledged open-source product.

The pictures folder on my instance is at 1.3GB after two days. It’s just me and my friend. About how many communities are you subscribed to?

• Trilium - Similar to Obsidian but open source.

I use TrueNAS Scale for my NAS and Ubuntu server for my VM’s/home server. I probably am forgetting something, but, that’s what’s listed in my Portainer :).
