Basically, just works with no issues, many users report problems when using programs like KDEconnect which is more than just filesharing and kinda bloated.
Actually Snapdrop and Pairdrop requires Internet and the remote server to function. It needed the remote server to kick-start the P2P connection between devices.
It uses a P2P connection if WebRTC is supported by the browser. WebRTC needs a Signaling Server, but it is only used to establish a connection and is not involved in the file transfer.
I wouldn’t recommend LocalSend, as you’ll have to allow port 53317 if you have firewall enabled. Otherwise, this thing wouldn’t work at all.
If you want to share files locally, securely, and at maximum speed, I recommend Warpinator. Especially, if you’re on Linux, Warp works the best with beautiful UI. On Android, I use Wormhole. It’s plain simple, and doesn’t require me to poke my firewall. It also works both ways, locally - extremely high speed through direct transfer without using the internet, and over the internet.
An internet connection is required and The best transfer method will be determined using the “Magic Wormhole” protocol which includes local network transfer if possible.
Magic Wormhole uses a public relay server to send data from one computer to another. This means that the data goes through a third party server before reaching its destination. This server is responsible for the initial handshake and the exchange of keys for encrypting the data.
The transferred data itself doesn’t consume data from ISP. The internet is only required for the initial handshake, thus the internet is needed for the warp to work.
I also tested LocalSend again with my firewall port 53317 opened. The app works as expected.
Edit: It was my mistake. Because my phone was on VPN, so sharing from my phone’s hotspot didn’t work. Now, everything works as expected with LocalSend.
I use kdeconnect as my main internal network transfer, if that is playing up I go to local send. Warpinator always had trouble setting it up, but today I had another go and got it to work.
According to you the application is safe, I would like a simple application like this to transfer my GOS files to my Linux, but first I would like to know if in terms of security and privacy, LocalSend can be trusted.
