A similar project but this one works entirely in the browser and can connect to clients beyond your local network with "public" rooms
Pairdrop is awesome! The docs are a bit hidden, the FAQ is at https://github.com/schlagmichdoch/pairdrop/blob/master/docs/... and the How-To for integration into Share menu on Android, iOS and Windows at https://github.com/schlagmichdoch/PairDrop/blob/master/docs/...
They forked sharedrop after it and snapdrop got acquired and enshittified by LimeWire, whoever that is now.
Should have been called PearDrop
I'll need to give this a shot. I have Localsend installed for sending thing between my iPhone and Linux desktop, but it doesn't always play nice. Even with the Localsend port open in Firewalld it can take upwards of 10 minutes for the devices to see each other. A browser solution should at least have faster discovery.
