I have not used Landrop but looking at it from the outside, Landrop is version 0.4 and has received no development for 3 years now. LocalSend is past 1.0 and still in active development. I'd rather use LocalSend then instead of something abandoned before it was deemed complete.
Thanks, this tends to be functionality I dont need that often but when I do it's frustratingly difficult finding something that doesnt feel like it's going to need me to sign over my soul so it's good to know about other open source solutions.
