Boolean

A Boolean variable holds true or false. Instead of a free-text field, the Variables panel shows a small true/false selector for its default value, so there's no way to type anything else in by mistake.

Compiles to

let isActive = true;

Get Variable / Set Variable

A Get isActive node reads it back; a Set isActive node assigns a new value and continues:

Get Variable

Set Variable

Use case

• Flags and state: A feature flag, an "is authenticated" state, or any other on/off switch you want to check and flip from the canvas.
