Always enjoyed scrolling though these posts, figured I’d give it a go here:
What are your must-have selfhosted services?
Some of mine:
- Adguard Home - Add blocker
 - Adguard Home Sync - sync multiple adguard instances
 - Bookstack - documentation
 - BorgMatic - config driven backup
 - Change Detection - monitor websites for changes, prices for example.
 - FreshRSS - RSS reader
 - Home Assistant - home automation
 - KitchenOwl - groceries
 - Rclone - sync backups to remote storage
 - Traefik - reverse proxy
 - Vikunja - todo list
 - Wireguard Easy - VPN
 


Yep, it just needs outbound connectivity. I run mine on an intranet like you, with VPN access for when I’m not at home.
