I freaking love my #SyncThing setup, it makes workflow across multiple devices on a local network — Linux and Windows desktops, an Android phone, occasionally even a Steam Deck — so easy and seamless! There's an initial learning/setup curve and at one point Windows threw a curve ball by arbitrarily switching folders around, but once you get used to the basic concepts things make sense, troubleshooting isn't too much trouble, and it's a breeze to flexibly configure folders for different uses like one-way backups (e.g. sending phone pics and footage to desktop) and two-way synchronization (e.g. keeping folders synced between desktops or between a desktop and phone).
