KEIBIDROP

Send files between any device.
Fast. Private.

No cloud storage. No accounts. No file size limit. Files go directly between your devices, encrypted so nobody else can read them.

Download Source Code

Free and open source. No sign-up.

What you get

No file size limit

Send a 5 KB document or a 500 GB video. There is no limit. Transfer resumes if the connection drops.

No accounts

No email, no password, no sign-up. Open the app and start sharing. Your files, your business.

Nobody can read your files

Files are encrypted on your device before they leave. If a relay is used, it forwards bytes it cannot decrypt.

Works everywhere

macOS, Windows, Linux, Android, iOS. Same app, same protocol. Send between a phone and a laptop, or two servers.

Same network? Even faster

Devices on the same WiFi find each other automatically. One tap to connect. No codes, no internet needed.

Open source

The engine is open source (MPL-2.0). Inspect the code, audit the crypto, build your own client.

Two ways to share

Direct Transfer

Pick files to send. Your peer picks files to download. Simple and fast. Good for photos, videos, backups, project folders.

Virtual Folder

Your peer's files appear as a folder on your computer. Open them with any app. Changes sync both ways. Like a shared drive, but encrypted and peer-to-peer.

How it works

1

Open the app on both devices

Each side gets a short code. Or toggle local mode and devices find each other on the same network.

2

Exchange codes

Send your code to your peer via Signal, WhatsApp, or any channel. They send theirs. On the same WiFi? Just tap their name.

3

Connect and share

One tap to connect. Drag files in, share folders, or use the virtual mount. Everything is encrypted end-to-end.
