From install to a shared folder in a few minutes.
KEIBIDROP puts another computer's folder on yours. You open it, read and edit files, and they stay on the other machine, streamed to you as you read them. Everything is encrypted end to end, and nothing is stored in a cloud.
Two people, or two of your own devices, run KEIBIDROP and connect once. Each side sees the other's shared folder as a normal folder in Finder, Explorer, or any file manager.
macOS: brew install keibidrop Linux: sudo dpkg -i keibidrop_amd64.deb Windows: choco install keibidrop
The install page has the full per-platform commands and direct downloads.
For the virtual folder, install a FUSE driver once: macFUSE on macOS, fuse3 on Linux, WinFsp on Windows. The install page lists the commands and the one-time approval step on macOS. If you only want to send files (Direct Transfer mode), you can skip the driver.
No codes to copy on a local network.
Save the other person as a contact to skip the fingerprint exchange next time. On a local network, saved contacts reconnect with one click.
It works through firewalls on its own. If a direct connection fails, KEIBIDROP falls back to an encrypted relay that forwards bytes it cannot read. No port forwarding, no router setup.
Once connected, the peer's shared folder shows up as a normal folder. On macOS it appears in Finder under the KEIBIDROP volume, on Linux at ~/KeibiDrop/Mount/, and on Windows as a drive letter.
Open it. The files are listed right away. Read one and the bytes stream from the other machine as your application reads them. A 10 GB file opens immediately, and only the parts you touch come across. Write a file into the folder and it lands on the other side.
| Direct Transfer | Virtual Folder | |
|---|---|---|
| What | Drag files in; the peer pulls what they want | The peer's files appear as a folder you can open |
| Speed | up to ~660 MB/s | up to ~250 MB/s |
| Needs | nothing extra | macFUSE / fuse3 / WinFsp (once) |
| Use it for | sending big files, folders, or many files at once | working on shared files, repos, projects |
You pick per connection. Most of what makes KEIBIDROP useful is the virtual folder.
Every install includes three interfaces: the desktop app (keibidrop) that most people use, the interactive terminal CLI (keibidrop-cli), and the scriptable agent CLI (kd), which prints JSON for automation and AI agents. See the agent CLI guide for the full command set.
See what you can do with it: work on a git repo from another machine, hand a database between computers, open large media files without downloading them.
