Linux sandbox
In-browser Linux via WebVM — no Docker on this server. Sign in optional.
Practice Linux commands in an ephemeral browser sandbox.
This is a free-play shell. Nothing is graded.
Try: uname -a, ls /, whoami.
Reload sandbox anytime for a clean environment.
No checklist — explore the sandbox, then mark the step complete.

Click Start sandbox for an in-browser Linux environment.
No Docker on the server — the sandbox runs in your browser (or an embedded lab host).
