Direct-transfer mode works on every platform without any driver. The driver is needed only for the shared folder (the FUSE mount).
macOS
Minimum version: macOS 12.
Driver: macFUSE. First install requires an approval in System Settings and one reboot. Steps: Install on macOS.
On macOS 15.4 and later, macFUSE can run through the FSKit backend. It runs in user space, with no kernel extension. Enable it in System Settings → macFUSE → Use FSKit.
The .dmg and all binaries in it are signed with a Developer ID and notarized by Apple.
The mount appears in Finder as the KeibiDrop volume.
Linux
The .deb targets Debian and Ubuntu on x86_64. Other distributions can use the .tar.gz.
Driver: fuse3. The .deb declares the dependency. For the .tar.gz, install it yourself.
/etc/fuse.conf must contain an uncommented user_allow_other line. KeibiDrop mounts with allow_other so other processes and service accounts can read the folder.
The desktop app needs a graphical session. The two CLIs run headless; a server install can skip the GUI libraries.
Windows
64-bit Windows with WinFsp. WinFsp 2.1 (the current stable) is recommended. The Chocolatey package installs WinFsp as a dependency.
The WinFsp 2026 (2.2) line is in beta. It carries FUSE fixes relevant to KeibiDrop and two security fixes. When 2.2 is stable, it becomes the recommended version.
The mount appears as a drive letter, for example K:. The mount point must not already exist; WinFsp creates it.
Windows binaries are not code-signed yet. SmartScreen shows a warning on first run. Verify the download against SHA256SUMS instead.
There is no .exe installer. Use the .zip or Chocolatey.
Mobile
iOS and Android apps exist and are in testing. They are not in the app stores yet. Mobile is transfer-only: it sends and receives files with the same encryption, without the shared-folder mount.
Releases
Desktop version for these docs: 0.4.0. Releases in the 0.x line are tagged Beta.
Every package contains the three interfaces: keibidrop, keibidrop-cli, kd.
Every release publishes SHA256SUMS. Verification commands are on each install page.
