Linux in Browser — Ubuntu 24.04 (CLI) Beta
A real Ubuntu 24.04 (noble) 64-bit system, emulated entirely in your browser with v86_64.
This page boots a genuine Ubuntu 24.04 (noble) x86-64 Linux system using v86_64, a fork of v86 that adds 64-bit kernel support. Everything — the CPU, the disk, the kernel — runs locally in your browser. Nothing you type is uploaded to any server.
user / user.
How it works
v86_64 emulates a full x86-64 PC — CPU, BIOS, disk controller and video — in WebAssembly, so a real 64-bit operating system can run inside a web page. On your first visit the browser downloads the small engine (a few MB) and the Ubuntu disk image (~1.5 GB) — you'll see a live progress meter with the percentage and megabytes. The disk, kernel and initrd are then cached in your browser's local storage, so every visit after that loads instantly with no re-download.
You can also make your changes stick: click Save VM state to write the VM's disk back to your browser, and it will be restored on your next visit. Use Reset to fresh image to discard your saved state and start clean, or Clear cached data to free the storage. The kernel boots, systemd starts, and you get a real shell on the serial console.
What you can do
This image ships with vim, nano, git,
curl, python3 and htop pre-installed. Try
uname -a to see the 64-bit kernel, ls / to explore the
filesystem, or python3 to drop into the interpreter. The VM is offline, so
apt-get install won't work — everything you need is already on the disk.
Performance notes
v86_64 is a software emulator, so it runs much slower than native Linux — expect boot to take around a minute or two and commands to feel sluggish. It's built for learning and exploration, not for heavy work. A faster machine and a modern browser (Chrome, Edge or Firefox) help a lot.
