https://pairdrop.net/ is a fork of SnapDrop with a more responsive maintainer (apparently: https://github.com/schlagmichdoch/PairDrop/discussions/115 )

That's the first file share app that doesn't miss the point (I don't want to install anything, just send a file).

Looks great but would it work between two smartphones out in the wild? Or does it require being on the same LAN.

also https://www.sharedrop.io/ it uses webrtc for local communication

Piling some more alternatives, a fork to snapdrop:
