I haven’t tried Sync-in but if simple is what you want then a Synology DS225+ should get you up n running quickly.

Which part of the seafile install was it that made you back off?

Ah, I forgot to mention I’m already running my own Debian server. Ideally, I wouldn’t have to buy another device just for online file management.

There’s proxies behind proxies behind proxies that proxy to proxies so you can proxy while you proxy.

I managed to install half of it, but then some of the many servers you need to install didn’t end up talking with each other. I tried studying the architecture for a bit, but still couldn’t figure out which server’s request I needed to rewrite in order for the other server to see it.
