I love Actual. It’s fantastic and easy to use. I use off-budget accounts and weekly / monthly reconciliation just to keep the general value of these accounts at stable intervals.
I have a slight bone to pick with the PWA version of the site though. After a couple months of using the PWA front end to keep my budget and transactions accurate manually, I opened the site on my desktop browser and it completely lost all that work due to a sync issue. Apparently the PWA for weeks had not remained in sync and so all manual entries were not making back to the server. But the app works so well I never noticed because it kept just working. Supposedly there’s an alert saying it’s not synced with the server but it’s not prominent enough. So if you use that feature (the PWA) then be sure it’s syncing often.
I would make the case for proxmox on the machine so you can divvy up the hardware as you see fit— but also setup the hard drives as a zfs1 pool (1 redundancy failure allowed). This way you can make multiple isolated machines or use LXC containers directly for apps, services, etc. while benefiting from ZFS’s excellent performance and reliability. I would say that TrueNAS Scale has been a bit of a letdown for me because it feels bloated, easy to make mistakes with complicated setups, and I have less control over the hardware. I don’t like how updates have fully broken apps. That said it is a reliable ZFS wrapper with more bells and whistles in the UI over what proxmox offers— caveat being that both can do everything if you want to take the time to learn ZFS commands.
There is also the TrueNAS based alternative HexOS that is more beginner friendly for just getting a nice NAS setup fast while still supporting apps / containers.
