Browser Linux vs Virtual Machine vs Live USB
There are three common ways to try Linux without replacing your operating system: a browser-based machine like Linux Online, a desktop virtual machine app, and a live USB stick. They differ most in setup effort, speed and where your files end up - this page puts the numbers side by side.
The comparison
| Aspect | Browser Linux (this tool) | Desktop virtual machine | Live USB stick |
|---|---|---|---|
| Install required | None | App + OS image (several GB) | USB writer app + a USB stick |
| Time to first shell | 2-5 minutes (one-time ~100 MB download) | 30-60 minutes first setup | 15-30 minutes plus a reboot |
| Speed | Late-1990s PC pace (emulated) | Near native | Native |
| Admin rights needed | No | Usually yes | Yes (boot menu) |
| Network inside Linux | None, by design | Yes | Yes |
| Where your work lives | This browser + exportable session files | Disk image on that computer | The USB stick |
How to choose
Choose the browser machine for quick, safe, zero-install jobs: practising commands, trying a risky script, teaching, or any locked-down computer where installing software is not an option - and for moving work between machines, since a session exports as a single file you can import elsewhere to resume exactly. Choose a desktop virtual machine when you need speed, 64-bit software or networking; choose a live USB when you want to test Linux on the real hardware itself.
