In development

A desktop app for QEMU.

Windows, Linux and macOS. It manages a library of virtual machines, shows the console in the window, and serves the same screen to a browser on your network.

Every machine is a file you can read, and the command line it runs is one click away.

What it does

Library: State, CPU, memory and uptime. Start, shut down, force stop, pause, reset. Machines keep running when the app closes.
Console: noVNC in the window, or a browser on your LAN behind a password. Send keys, paste text as keystrokes, take screenshots.
New machines: Linux cloud images with a user, SSH keys and packages. Installer ISOs. Windows 10 and 11 unattended with VirtIO drivers. macOS via OpenCore.
Hardware: Machine type, CPU and topology, memory, UEFI, TPM, disks, NICs, port forwards, USB, boot order, raw arguments — limited to what your QEMU build supports.
Disks: Snapshots, resize, clone as a copy or an overlay, convert format, export to a folder that imports again elsewhere.
Acceleration: Says so when QEMU falls back to software emulation instead of KVM, HVF or WHPX.

Requirements

Windows 10/11: QEMU for Windows, and Windows Hypervisor Platform turned on.
Linux: qemu-system-x86 and ovmf, plus swtpm for a TPM. Join the kvm group.
macOS: brew install qemu.
No QEMU yet: One button installs it with winget, Homebrew or your package manager.

Status

Version: 0.1, in development. The core is tested; expect rough edges.
Installers: Not published. Build from source with Rust (stable) and Node.js 20+.
Licence: Undecided.
