A whole Arm64 computer

Stock operating systems boot on it unmodified, with the devices and graphics a desktop wants.

Systems

Stock operating systems

Alpine, Debian, Arch Linux ARM and FreeBSD boot from the same kernels and disk images you would give a real Arm server.

Board

QEMU’s virt machine

The same board and the devices guests expect: disks, network, display, keyboard and tablet, USB, sound and shared folders.

Graphics

3D on the host’s GPU

Wision, Warm64’s own graphics driver, draws OpenGL, video and whole desktops on the host’s GPU.

Snapshots

Snapshots, GPU included

Save a running machine, its graphics memory with it, and pick up where it left off.

Platforms

Browser and Node

The same machine runs in a browser tab and in Node.

Interface

Driven like QEMU

WEMU speaks QEMU’s command line, QMP and monitor, so scripts written for QEMU keep working.

The numbers

Measured on an Apple M3, in Node. Details are in the notes at the bottom of the page.

About 4 s

for a cold Alpine Linux boot to its shell.1

About half

of native speed on md5sum, recursive calls and sorting.2

8 cores

running side by side on the host’s own cores.

16 GB+

of guest RAM, in one machine.3

Free for copyleft projects. Licensed for business.

Warm64, Wision included, is free to evaluate, and free in production for projects whose complete source is public under a strong copyleft license, such as the GPL or AGPL. Everything else takes a commercial license.

Conditional Free License

Free for copyleft projects

Evaluate it for as long as you like. Ship it free in a project whose complete source is public under the GPL or AGPL: its copyright holders add a one-line permission for Warm64 to its license. The free build shows a notice for five seconds when it starts.
