• (2025-07-17) Emil Örn Kristjánsson: Amazing, it just works!
• (2025-04-24) P A: Very helpful and works quickly!
• (2025-04-11) Amine Kaddar (Chabache): Just perfect! Thanks Suggestion: please add wearable and maybe custom screen size for ioT like apps.
• (2025-03-06) Ira Bailey: Best app/extension there is for quick mobile testing ❤️
• (2024-11-04) Ahmad Oweis: Works great! I'm testing my e-commerce website, and it is a lot easier this way, especially when making changes to the website I can force refresh easily now!
• (2024-09-21) Somanshu Singh: Pretty good. gets the job done. But it should be more like Figma where the design is on the canvas and we can use keys like ctrl and shift to navigate.
• (2024-09-07) Jim Wharton: Doesn't seem to work. It flashes for a second and then disappears.
• (2024-07-10) Andrew Watts: Does this even work?
• (2024-05-24) Drica Sampaio: I would love to use it but with a Wix Site link, all the devices were previewed as mobile, desregarding the desktop formats that I needed to see :(
• (2024-03-07) Nick Greenup: After using this for 10 minutes, I already love it and suggested everyone on my team grab this extension. I only wish there was a way to contact the developer so I can thank them and buy them a coffee cause this is awesome.
• (2024-02-15) Stephen Drake: really really great extension. wonderful and amaziong. but i think the resolution of the device is not correct, because I think I need higher resolution to test on a phone device, I dont know if that is possible. thank you very much.
• (2024-01-19) Alex Graham: Doesn't work consistently on localhost. Causes some background colors to change. Aside from those issues, this is the best extension I've found for viewing both desktop and mobile views at once.
• (2023-12-27) Belajar Mac: A new must-have chrome extension for me. It's straightforward, useful and easy to use. I stumbled upon it accidentally while searching for extensions for responsive design. One suggestion, please add a feature to configure the devices height and also feature to see the devices inlined rather than stacked (horizontal scroll). This will help us in simultaneously scrolling through all the devices and seeing the effects concurrently.
• (2023-12-20) Gabriel Moncea: Very useful. Missing a dark mode feature :D
• (2023-12-17) Martin Richta: An impressive and useful extension. Here, too, there is room for improvement. What I miss the most is the option to reduce (zoom) like in Devtools, so that I can reduce the display of the test page. When I test at a resolution higher than my monitor, I can't see the entire test display. If he could reduce them to 50% I would see everything and get a better idea. The second thing is the possibility of setting your own sheet.
• (2023-12-11) Al Murray: Does the job.
• (2023-12-11) Peter: Really simple to use. I absolutely love the common breakpoints. I just wish there was an easier/quicker way to deselect devices.
• (2023-11-28) Dominik Krakowiak: Love it, makes testing a lot easier. Thank you.
• (2023-11-22) Dragos Stancu: I can test on multiple screen sizes inside the same browser tab. Works great on my 27"! And I can simply rotate the iPad view to cover laptop screens as well. Very easy to use.
• (2023-11-15) Ben Miller: By far and away the simplest solution I have yet found, and so nearly perfect. My only request would be to be able to add custom viewport sizes as none of the predefined ones hit my small or large breakpoints (Tailwind CSS defaults).
• (2023-11-14) Richard Murnane: Very slick piece of work that takes a lot of the headaches out of testing what your web creation looks like on different devices.
• (2023-10-25) Jeremy Wells: Really useful extension

• (2023-10-24) Leandro Nuñez: It's easy, intuitive, clean. I would just change the design to be minimal, but the experience is great.

• (2023-10-23) Amar Desai: Great, thanks for this! Can you add more misc devices? Like Galaxy Fold unfolded and folded? Or maybe a laptop screen?
