You should know that WebRTC is not ideal for this use-case, it has inherent performance and discovery issues. All web-based solutions are flawed until hypothetically the browsers and/or WebRTC step up their game. Fine for a pdf or something, but try it with large files and you’ll very likely have a bad time.

I must say LocalSend seems pretty great (even though they’re a “direct competitor” to my app https://payload.app/ )
