Transfer files over WiFi without internet
You are at a conference, on an airplane, or in an office where the internet is slow or restricted. You need to get files from one device to another. Both devices are on the same local network but there is no route to the outside world.
Cloud-based file sharing does not work here. Google Drive, Dropbox, WeTransfer all need an internet connection to upload and download. Even if you just want to send a file to the person sitting next to you.
Local mode
KEIBIDROP can discover devices on the same network automatically. When both devices are on the same WiFi or wired LAN, they find each other without contacting any server. The connection is direct between the two machines. All data stays on the local network.
The transfer speed is limited by your local link, not by any internet bandwidth. On a good WiFi connection, large files move in seconds.
No internet at all
If neither device has internet access, the automatic discovery still works over the local network. You exchange codes by showing your screen to the other person or reading the code out loud. Once connected, everything happens locally.
When internet comes back
KEIBIDROP also works over the internet for devices that are not on the same network. It connects directly when possible. If firewalls block the direct connection, a relay forwards encrypted data that it cannot read. You use the same app in both scenarios.
Encrypted either way
Whether the transfer is local or over the internet, the connection is encrypted end-to-end. Even on a shared WiFi network where others could intercept traffic, the file contents are protected. The encryption is quantum-resistant, designed for both current and future threats.
