Real scenarios that run in your browser. No install, no VM, no account to start — just a prompt and a puzzle.
A genuine kernel with a real filesystem, users and groups, a process table, and a simulated network — the same commands behave the same way you'd expect on a real box.
mkdir, cp, mv, symlinks — a real tree you can build, break, and fix.
Users, groups, chmod, sudo — ownership actually gates what you can touch.
ps, kill, background jobs — a process table that lives and reacts.
curl, ping, ports — scenarios talk to a simulated network.
Browse the store and open anything that looks interesting. Guest-playable.
Files, permissions, processes, networking — a genuine terminal, in the browser.
Sign up to sync saves across devices and unlock AI hints when you're stuck.
Every scenario and command is rated, liked, and reviewed by the people who played it. Sort by top-rated, most-played, or newest — and claim community commands into your own sandbox.
