The README and website certainly seem polished, but I haven't used the utility yet.

What's the main value prop over wormhole? That it works from the browser?

That you can send over 1000 files without it messing it up, and they'll end in the right place.

That you can set the recipient so it will auto-accept from the trusted senders.

And for me that in Android I can do Share to....localsend to do it faster than with wormhole.
