Terminal User Interface
Switchyard has an experimental terminal user interface (TUI) available on both Linux and macOS. It works more or less as the Adwaita GUI does, but from your terminal, with the limtiations that entails.

The TUI was built for internal testing and porting to macOS, but is feature-complete and uses the same backend that the GUI does. You can use it to launch links, including switchyard:// URLs, from your terminal or from a scripting language of your choice.
Usage
Clone the repo, then build the TUI binary from the cmd/sw directory:
go run ./cmd/sw
Or, just use Nix:
nix run .#sw
You may pass your URL as a command line argument:
sw https://switchyard.aly.codes
