Guestbay is a desktop app for virtual machines, built on QEMU. See every virtual machine in one library, work in its console right in the window, and set up new Windows, Linux and macOS guests without writing a command line. • Create machines from templates: Linux cloud images with your user and SSH key, Windows 10 and 11 installed unattended, installer ISOs, and macOS through OpenCore. • Download Linux images from their publishers, checked against their checksums, and follow built-in guides for Windows and macOS installation media. • Run at full speed with Windows Hypervisor Platform. Guestbay tells you if QEMU falls back to slow software emulation. • Edit hardware: CPU, memory, UEFI, disks, network cards, port forwards, USB and boot order. • Take snapshots, and resize, clone, convert and export disks. • Machines keep running when you close the app, and Guestbay reconnects when you open it. • Reach the same interface from a browser on your network, with a password and HTTPS, when you turn it on. • See the exact QEMU command line behind every machine. Try Guestbay free for 30 days. After the trial, buy it in the Store to keep using it. Requires Windows 10 or 11 on an x64 or ARM64 PC, with Windows Hypervisor Platform turned on. Guest operating systems need their own installation media and licences.
