Run JavaScript in the preview

Sandboxed, and isolated from this siteThe preview runs in a frame with its own opaque origin, so scripts you paste can run but cannot read anything belonging to this site — including saved settings or anything stored by the other tools. Your code stays in the browser and is never uploaded.
