it'll be very good. it won't resolve conflicts for you, though - just like Dropbox or Google Drive also wouldn't. It's last-write-wins, so you either need to keep your devices connected and syncing at all times, or you need to be careful when you edit the same files on different devices.

I use Syncthing for all kinds of things and it's excellent, but it's not really a silver for bullet for mutable data like text files.

I have a small vps as one of my syncthing nodes, and every device syncs with that central server in addition to syncing with eachother. This removes the need to keep everything online at the same time as the vps is always online, receiving and propagating changes from any device.

Yeah me too. I love syncthing but prefer using it with an always on 'server' like dropbox rather than just pure p2p.

What I really like about it is that you don't have to sync everything everywhere. I have work folders I sync with just my work machines, and personal ones that go to my personal VPS.

I'll look into it, thanks for the suggestion! The risk de-synchronization poses can probably be mitigated with automated local backups.

BTW, just a second vote for Syncthing, here. It's basically my "move data around" Swiss Army knife.

Need to get my Keepass database on my phone? Syncthing.

Need to back up my reMarkable to my NAS? Syncthing.

Need to replicate game saves between my PC and my Steamdeck because the game doesn't support Steam Cloud Sync (I'm looking at you, Subnautica)? Syncthing.

I run Paperless as a document management system and use Genius Scan on my phone. I use Syncthing to automatically move scans from my phone to the Paperless inbox folder.

And none of that data resides on a third party cloud. Just encrypted, peer-to-peer sync. It really is fantastic.

I went to Syncthing.net and they didn't mention iOS or Android.

Does it run on those?

If I can ask, what is Paperless? Google is strangely unhelpful.

It's a self-hosted document management system:

https://docs.paperless-ngx.com/

Think: replacing paper file folders with a digital system. Supports OCR, a variety of metadata, tagging and categories, etc.

My primary use case is taxes, but for any important legal or financial documents, I throw 'em in Paperless.

I can’t recommend Paperless enough. I set up email forwarding to the Paperless ___domain and it automatically downloads the attached documents. The only problem I have now - I am using a somewhat older version and there’s no direct migration path to the recent one.
