How does localsend work exactly? I've read both their website and Github README as well as part of their protocol docs but I still have no idea. How does the initial device discovery work? For file transfer does it use the local wifi, some external server, …?

It looks like they implement something similar to Bonjour [1] using multicast DNS [2]. Not sure if it's basically a reimplementation like Avahi [3] or if it's a slightly different protocol (only skimmed the code [4] briefly).
