I recently discovered Syncthing, an open-source tool for syncing files across multiple machines. Setting up Syncthing on my personal devices was easy, but I went on an interesting journey deploying it to a cloud server. Why run Syncthing in the cloud? Syncthing synchronizes files peer to peer. That means that at least two of my devices have to be online and running Syncthing simultaneously to stay in sync. If I change a file on my desktop, shut it down, and then take my laptop with me on a work trip, my laptop won’t pick up the changes I made on my desktop.
