Someone mentioned it in a comment and I genuinely didn’t know what I was setting up, but its basically airdrop but to all your devices/servers so if you have an iphone like me you can goto any photo/file click share, taildrop, then pick the device, its a prettty fast transfer. It shows up in the downloads folder on my pc by default.
I no longer have to upload to icloud files to grab my files, it is very convenient and seems to be free forever for personal use up to 100 devices? I had no idea what I was even setting up til I saw the guide afterwards, I thought it was for monitoring server health, but it’s made sharing files between devices/servers very convenient. (this was likely obvious, just wanted to share with others who didn’t know)
You can also use something called wormhole. Very handy tech.
Also portal which is LAN aware.
