Everything you need to know

Short answers about price, privacy and how accurate a simulator really is.

Is PocketView free?

Yes. The free version shows 2 devices side by side, with every device, sync scroll, screenshots, recording and Mockup Studio included. A Pro plan with more devices at once will come later, with one clear price.

Does it work with localhost and staging sites?

Yes. Open http://localhost:3000 or any staging URL the same way as a live site. Your own browser loads it, so password-protected staging sites work when you are signed in.

Is it a real iOS or Android simulator?

No, and we say so plainly. PocketView simulates screen size, pixel ratio, user agent, touch and display mode inside Chrome. Layout and responsive CSS behave like on the device, but Safari engine bugs only show on a real iPhone. Do a final check on a real phone before a big launch.

Does PocketView collect my data?

No. There are no accounts, no analytics and no servers. Settings stay in your browser. Read the privacy policy.

Which browsers does it support?

Google Chrome, plus browsers that install Chrome Web Store extensions, such as Microsoft Edge, Brave and Arc.

How is it different from Chrome DevTools device mode?

DevTools shows one device at a time inside the inspector. PocketView shows devices side by side with real frames, syncs scrolling between them, and adds foldables, recording, mockups and app mode. See 3 ways to get mobile view in Chrome.
