I've personally used Snapdrop and Croc before and they're both very nice
AirDrop's use of wireless technology to discover (bluetooth) & connect (wifi) devices remains a great frontier few have explored or tapped. Sad.
Edit: Apparently some support for linux is possible.
> As AirDrop exclusively runs over Apple Wireless Direct Link (AWDL), OpenDrop is only supported on macOS or on Linux systems running an open re-implementation of AWDL such as OWL.
I've been fiddling away with OWL and OpenDrop for a few months now, trying to get it working on a Raspberry Pi Zero.
The goal was a digital picture frame that accepts Bluetooth and AirDrop pictures. The bluetooth part works fine... but it's the Airdrop part that's dead in the water at the moment.
