Loading the emulator…

The PC runs in this tab. Files you add stay on your device.

THREE SIMPLE STEPS

How to use the PC emulator

Pick a system

Choose Linux, FreeDOS or KolibriOS. The first start downloads it once (2 to 10 MB); after that it starts straight from your browser.

Click the screen and type

Your keys go to the emulated PC while its screen has focus. Use the key row for Esc, arrows and function keys on a phone.

Move files and save

Add files to the PC, download what it writes, paste text in, and save the machine to pick up where you left off.

THE SYSTEMS

What you can run

Linux

A small Linux built for this page: a root shell with the BusyBox tools, the nano editor, htop, Lua and MicroPython. Files you add appear in /mnt/shared, and a second shell runs on the serial terminal for easy copy and paste.

FreeDOS

DOS as it was: C:\> prompt, batch files, the EDIT text editor and the DEBUG assembler, plus nine free games (Tetris, Floppy Bird, Sudoku, Snake and more). Your files are on drive B:.

KolibriOS

A complete graphical operating system that fits on one floppy disk, written in assembly language: desktop, file manager, text editor, image viewer, games and demos. Click the screen to use the mouse.

PC emulator FAQ

Is this online PC emulator free?

Yes. It is free with no account, no time limit and no watermark on screenshots, and every system it runs is free software.

Can I run Linux or DOS in my browser?

Yes. Pick Linux, FreeDOS or KolibriOS and it boots on an emulated PC right in this tab in a few seconds, with nothing to install.

What programs can I run?

Linux comes with the BusyBox tools, nano, htop, Lua and MicroPython; FreeDOS has EDIT, DEBUG, batch files and nine free games; KolibriOS has a full desktop with a file manager, editor, image viewer and games. You can also add your own programs, documents and scripts through the Files panel.

How do I get files into and out of the PC?

In Linux, files you add appear in /mnt/shared; copy files there to download them. In FreeDOS, your files are on drive B: (a 1.44 MB floppy); programs can save to B: and you download the changed files from the Files panel.

Is my data private?

Yes. The PC runs entirely in this tab: files you add are copied into it on your device and are not sent anywhere. The emulator and the system you pick are downloaded once and kept in your browser's cache.

How fast is it?

It translates the PC's code to WebAssembly as it runs, so DOS programs and the Linux shell feel responsive on a recent laptop. The speed in millions of instructions per second is shown next to the system name.

How do I save my progress?

Save state stores the whole machine — memory, screen and disks — in your browser. Next time, choose Resume on the system's card to carry on where you left off.

How do I send Ctrl+Alt+Del and other special keys?

Use the Ctrl+Alt+Del button in the toolbar. Most other keys, including Esc, Tab and the function keys, go straight to the PC while its screen has focus.

Where do these systems come from?

Linux was built for this page from Buildroot, the FreeDOS disk was assembled from the official FreeDOS 1.4 packages, and KolibriOS is the project's own floppy image. About this system lists every program with its licence and source code.
