osmatrix-guests

Run commands, start background processes, copy files, forward ports in both directions, take screenshots and send keyboard/mouse input in local Ubuntu, Windows and macOS guests. Use when code must be run or debugged on another OS ("test this on Windows/macOS"), when a dev server inside a guest must be reached from host tools (browser, curl, Playwright), when a guest needs a service running on the host, or when a GUI app inside a VM must be driven.
