Es lo mismo. TempMV viene de «Temp» (temporal) y «MV» (máquina virtual); en inglés se escribe TempVM, de «Temporary Virtual Machine». Las dos formas llevan a tempmv.cloud.

¿Qué es una máquina virtual temporal?

Una máquina virtual temporal es un ordenador virtual desechable que vive solo mientras lo usas. En TempMV se ejecuta dentro de tu navegador y desaparece al recargar la página.

¿Necesito instalar algo o crear una cuenta?

No hay que instalar nada: TempMV funciona íntegramente en el navegador con WebAssembly, y puedes arrancar máquinas del catálogo sin cuenta. Una cuenta gratuita desbloquea el resto —el curso de Linux, las redes virtuales, las plantillas, la comunidad— y conserva tus máquinas entre visitas.

Why TempMV

Truly temporary

Every machine lives only in the page's memory. Reload and it powers off and vanishes — a disposable test bench by design.

Real x86, not a mockup

A real CPU runs real machine code with the v86 hypervisor compiled to WebAssembly: BIOS, video, keyboard, disk and clock.

Your machines stay on your device

Machines run in your browser, and the disk images you load are read locally and never uploaded. An optional account only saves settings, progress and machine recipes — never disk contents.

Build from JSON

Define a machine in a live JSON editor and watch it take shape, or pick a ready-to-boot base from the catalog.

Three steps to a running machine

Pick a source
Start from a base system, from scratch, from your own disk image, or from a JSON definition.
Boot it
Tune RAM, video and boot order, then power on. The virtual CPU starts booting in seconds.
Throw it away
Done? Just reload. Want to keep it? Save a template, export the state, or take snapshots.

Frequently asked questions

TempMV or TempVM?

Both. TempMV is "Temp" (temporary) plus "MV", the Spanish máquina virtual; in English it's often written TempVM, for Temporary Virtual Machine. Either way, you're at tempmv.cloud.

What is a temporary virtual machine?

A disposable virtual computer that exists only while you use it. In TempMV it runs inside your browser tab and disappears when you reload the page.

Do I need to install anything or sign up?

Nothing to install: TempMV runs entirely in the browser with WebAssembly, and you can boot machines from the catalog without an account. A free account unlocks the rest — the Linux course, virtual networks, templates, the community — and keeps your machines between visits.

Is it free?

Yes, completely free. The machines run on your own device, and the site is supported by ads on the reading pages and by sponsors.

Ready to spin one up?

Mount a temporary x86 machine and boot it in seconds. What happens in the room stays in the room — until you reload.
