Is css scanner safe?

Clean risk

css scanner can send selected page HTML and CSS to codepen.io when exporting to CodePen.

When you use the CodePen export button, css scanner builds a CodePen form containing the selected page element's HTML and matching CSS rules. It submits that data to CodePen so the snippet can open there.
