We are currently in the open beta phase. Each update introduces more polished functionalities, loaded with extra features.

Panes

The extension starts with a default responsive pane. To add more, simply click the “+” icon. You can select from available presets, create your own for customized testing, or add another responsive pane

Inspect

Inspect anything, measure everything

Inspect Mode gives you powerful tools to analyze and modify elements on a page. You can check CSS styles, add custom CSS, measure distances between elements, and download images.

Edit

Edit any text, replace any image

User Agent Strings

Mimic Real Devices

Easily switch between user agent strings to emulate real devices. You can select from our preset options or add your own custom user agents to see how your website performs across different devices.

X-Frame-Options

Header Bypass

Some websites prevent content from loading in iframes due to X-Frame-Options settings. Use our extension to bypass these restrictions and view the content within an iframe, ensuring you can fully test and interact with embedded pages.
