A real box, ready in seconds.
Sign in, click create, get a terminal. boxctl boots you a real box — fully isolated, all yours — without a cloud account, SSH keys to manage, or a dashboard to learn.

Start from a template
Pick a ready-made image from the onctl-templates catalog instead of starting from a blank box.
