Great extension. I like that you can compare different devices at the same time. Would be nice to have the actual mobile device outline but this still gives you the precise view on most mobile devices.

AI product read

Mobile device simulator for responsive web design testing

Allows developers and designers to test how websites look and behave on various mobile devices and tablets directly within the Chrome browser, without needing physical devices.

User opens the extension popup, selects one or more devices from the library (or creates a custom device), and clicks 'Open Selected'. The extension then injects iframes into the current tab, resizing them to simulate the selected devices. Users can toggle sync scrolling and device frames. The simulated views display the current page URL at the selected dimensions.

Target users: Web developers / UI/UX designers / Frontend engineers / Responsive design testers

The extension is a simple local tool with no external API calls for core functionality, so the analysis is based entirely on static code inspection. No dynamic testing was performed to verify runtime behavior or check for hidden network calls.

Monetization

No paid features detected

The extension contains no payment logic, subscription management, or billing APIs. The word 'Pro' in the title and UI ('Mobile Simulator Pro') appears to be a marketing name rather than indicating a paid tier, as all features (device selection, sync scroll, custom devices, multi-view) are fully implemented and accessible in the source code without any gating or license checks. The extension uses only chrome.storage.local, which is free.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension is a local Chrome extension that simulates mobile devices by injecting iframes into the current tab. It uses chrome.storage.local for settings and chrome.scripting for injection. There is no code for authentication, login, or account creation. The core workflow (selecting devices and opening them) works immediately without any login.
