Cross-platform application for easy encrypted file, folder, and text sharing between devices.

Rymdport (formerly wormhole-gui) is a cross-platform application that enables easy and secure sharing of files, folders, and text between devices. It ensures end-to-end encryption using the same protocol as magic-wormhole, allowing communication between Rymdport and other wormhole clients.

The transfers are implemented using wormhole-william, a native Go implementation of magic-wormhole. This results in a single native binary compilation without any runtime dependencies, while surpassing the performance of the reference implementation of magic-wormhole.


Please visit the release page to download the latest version. Pre-built binaries are available for various operating systems, including FreeBSD, Linux, macOS (x86-64 and arm64), and Windows (x86-64).

For Linux users, Rymdport is also available as a Flatpak on Flathub.

Additionally, binary packages can be found through respective package managers of the following distributions:

[Packaging status]

Running on macOS arm64 (M1/M2)

macOS puts unsigned binaries downloaded from the web into quarantine, except for Apple computers with Intel CPUs. You can remove the quarantine attribute from the application by running the following command:

xattr -r -d com.apple.quarantine <application path>

If this doesn't work, the amd64 binaries work fine through Rosetta.


Rymdport compiles into a statically linked binary without explicit runtime dependencies. Compiling requires a Go compiler (version 1.18 or later) and prerequisites for Fyne.


Systems satisfying the compile-time requirements can build the project by running go build in the project root directory. Alternatively, GNU Make can be used for compilation and installation (supported only on Linux and BSD): make and sudo make install.

For more information, refer to the Compiling page in the Rymdport Wiki.

The word "rymdport" ([rym:dpor‿t:]) comes from the Swedish language and translates to "space gate." As a wormhole serves as a gateway through space, it became the new name after "wormhole-gui."
