Open drpl.co on two devices connected to the same network. They find each other automatically. Click a device to send files or messages. The receiving device has to accept before anything is sent, and the files then move directly between the two devices, encrypted.
The server introduces the devices to each other and gets out of the way. The one exception is when a firewall or VPN blocks the direct connection: drpl then relays the data through the server so the transfer still works, and says so in the Transport row while it happens.
