Device Simulator is a focused workspace for exploring how a website feels at different screen sizes. It is built for developers, designers, and anyone reviewing a responsive page.
Built around the page
Paste a URL, choose a device, and interact with the website. The controls stay outside the preview so you can concentrate on the content. Rotation, fullscreen, and visual scaling make it easier to inspect layouts without changing the underlying viewport.
Clear about its limits
Device Simulator is a responsive viewport preview, not a hardware emulator. It runs in your browser and respects the embedding restrictions set by other websites. It is an independent tool and is not affiliated with or endorsed by Apple or Google. Device names identify the available viewport presets.
Free and straightforward
No account is needed. The tool does not keep a browsing history or upload entered URLs to an application backend. See the privacy page for details about embedded websites and hosting.
