Showesome

This chrome extension captures your website in multiple view ports to showcase your website designs. There are more than a dozen themes included. User can choose one of a them from the panel that appears in the options page.

There are also available additional settings like color gradient picker which lets user create a colorful gradient background, or image picker where they can choose image background, or decide whether to use reflection on devices as well as select reflection type (full, short, etc.).

Extension is using chrome debugger to change view ports on the page so it can capture various screens sizes (mobile, tablet, desktop), so the popup will appear on the top of the browser saying that chrome is debugging your page and it will close immediately after showing capture results.
