Responsive Preview

Preview websites across multiple device screen sizes simultaneously.

Responsive Preview helps developers and designers test how websites render across multiple screen sizes without manually resizing the browser. Open a responsive dashboard to view mobile, tablet, and desktop layouts side-by-side while interacting with the same page. Designed for front-end development workflows, it enables efficient visual comparison across viewports. Key Features: **Multi-Viewport Preview** Open the current website in multiple device-sized frames at the same time to compare responsive layouts across common screen resolutions. **Synchronized Scrolling & Interaction** Scrolling and basic navigation actions can be mirrored across preview frames to maintain consistent page position during testing. **Layout & Alignment Aids** Optional grid and ruler overlays help evaluate spacing, alignment, and responsive breakpoints during design checks. **Flexible View Modes** Switch between grid, stacked, or single-device focus views depending on your testing needs. **Custom Screen Sizes** Add and save custom viewport dimensions and orientations for specific devices or project requirements. **Zoom Controls** Scale the preview workspace to fit different monitor sizes and resolutions. **Privacy** Responsive Preview does not collect, transmit, or store personal data. All extension settings are stored locally in your browser using Chrome storage. The extension only accesses the active tab to display the current page in responsive preview frames. **How to Use:** - Open any website. - Click the Responsive Preview extension icon. - The responsive dashboard opens with multiple viewport previews. - Compare layouts and test responsiveness across screen sizes. - Responsive Preview is intended for web development and responsive design testing. It does not modify website content or bypass site restrictions.
