KEIBIDROP and AirDroid

A phone suite behind an account, or two folders joined.

By Marius-Florin Cristian · 27 September 2026

AirDroid manages a phone from a computer: files, notifications, messages and remote control, behind an account, with a free plan that shows ads and limits the size of a file sent away from the local network. KEIBIDROP does one thing. It joins a folder on one machine to a folder on another, with no account, no ads and no size limit, and it mounts the folder so you open one file instead of receiving all of them.

Files only, with nothing in the way

KEIBIDROP joins two folders and stops there. There is no account to create, no ad in the app, and no limit on the size of a file or a folder. AirDroid covers more of the phone, and its free plan limits the size of a file sent away from the local network.

Browse the other side and pull one file

KEIBIDROP mounts the other machine's folder as a folder on yours, and a read pulls only the bytes it touches, so you open the one file you came for instead of receiving a whole directory. It is a real filesystem, so Premiere, Resolve, Blender, grep and git open a path on it the way they open a local one.

Add files in a browser, open them on demand elsewhere

Open web.keibidrop.com, add files, and pair with a desktop that runs KEIBIDROP. The desktop sees the files in its mounted folder and pulls only the bytes an application reads; a terminal or an agent does the same through kd. The other direction works too: the desktop's folder is listed in the browser and a file downloads when you ask for it. Two browsers can pair the same way.

Limits

Platforms. Windows, macOS, Linux and Android today, and iOS is next.
Sending needs no driver. A whole file transfers with nothing extra installed. Add WinFsp, fuse3 or macFUSE on the machine that mounts, and the same folder opens in place: files open on demand and only the bytes an application reads cross the link.
Both peers online. A share joins two machines that are both running.

Common questions

Is there a file size limit?

KeibiDrop has none. AirDroid's free plan limits the size of a file sent away from the local network, and the paid plan lifts it.

Do I need an account?

No. Two KeibiDrop peers exchange an 86 character fingerprint once and connect on it afterwards. AirDroid needs an account on the phone and on the computer.

Can I read notifications or control the phone?

No. KeibiDrop moves files and mounts folders. AirDroid does both and more, and the two run side by side.
