A few years ago I was in a Arma3 Milsim group that hosted their own server.

Back then there was no automated way to sync plugins so we installed syncthing and told all users to install it too.

We put like 50gigabytes worth of addons on syncthing and the users were so much happier because since 50+ people were using this syncthing connection, everyone could download with full speed from the others as in contrast to the 100mbit/sec bandwith of the HTTP server we formerly used.

And nobody had to care about checking versions anymore, the syncthing folder was directly synced into the Arma3 plugin directory

That is not a bad model if you completely trust the server owners. I feel there are more secure ways, but I suspect if a Arma3 server wanted to infect a machine with a bad mod they could. so the threat vectors are the same really.

I’ve used syncthing sporadically over the years, but it has had very bad iOS support whenever I’ve tried it.

Mobeus exists, but doesn’t integrate into the files app, and uses a lot of battery.

I also used Resilio Sync for years, but it appears to have more or less died out.

So when it came to finding a replacement I settled on using cloud native for synchronization, and simply put encryption on top, and for that, Cryptomator is great.

I use CryFS combined with SyncThing, perfect solution for my needs. Have it set up on linux and android.

I tried many, many sync solutions (I self host a lot) but syncthing always looked weird to me.

One day I forced myself to actually configure it and, boy, what a wonderful product it is.

It takes some time before you have the eureka moment but then the flexibility of the tool us incredible.

It is hard to keep track of the links so I wrote https://github.com/wsw70/syncthing-map to ease the pain a little bit.
