Mobile View Batch Tester

Batch test responsive mobile views, device viewports (iPhone, Pixel), and user-agents in tabs or standalone popup windows.

**Mobile View Batch Tester** helps developers and QA teams inspect how web pages render at different viewport sizes. Add up to 50 URLs, choose a device configuration, and open the pages for quick viewport checks without repeatedly configuring Chrome DevTools. **Key features** • Batch processing for up to 50 URLs • Preset and custom viewport dimensions • Portrait and landscape orientation • Current tab emulation • Standalone testing window • Keyboard navigation between URLs • Tab level session isolation • Local browser execution The extension uses the Chrome DevTools Protocol to apply the selected viewport configuration to the testing tab. You can adjust dimensions, device pixel ratio, touch behavior, and user agent settings where supported. Testing happens locally in Chrome. The extension does not use a cloud device farm, analytics, telemetry, or remote URL processing.
