Click to view full sizePhone Simulator is a Chrome extension designed for developers, designers, and QA teams to test and preview websites on real mobile device sizes directly within the browser. It allows users to emulate popular smartphones and tablets, providing accurate viewport dimensions and pixel ratios to validate responsive layouts and mobile user experiences. This tool supports over 30 device presets, offers one-click screen rotation, and displays websites using an OS-adapted browser UI with realistic device frames. Compatible with modern frameworks like React, Vue, and Angular, it enables efficient mobile testing across local development environments, staging, and live sites. Unlike Chrome DevTools, Phone Simulator focuses on realistic visual previews, facilitating easy detection of layout bugs and usability issues early in the development process, all without the need for actual devices or external tools.
