Also included
➡️ Free downloadable transparent device mockups
➡️ Option to switch to landscape mode

Mobile FIRST has been the most powerful and reliable simulation extension for over 5 years.
Our rating on the Chrome Store speaks for itself.
✨ It integrates many technical tricks to reproduce the mobile experience as closely as possible.
Of course, this does not replace testing on a real device at the end of your development for full validation.

- Carlos Zambrano
- Very nice tool for mobile view, but you have placed too many ads that is making it buggy and very annoying to use, the modal ad I receive every refresh I made into my app to test the mobile view is super annoying and most of the times breaks the mobile view to not show anything. I will gladly change my rate if you find out another way to place the ads in a way that is not so annoying.

- The extension itself is well-made, the UI is clean, the device mockups look great, and it's genuinely useful for quick responsive checks. However, charging €8/month (or €60/year on yearly billing) to unlock devices newer than 4 years old feels completely disproportionate to the value. At its core, this is a curated library of device resolutions with visual mockups, functionality that most browser DevTools offer for free, minus the pretty frames. I understand the need to monetize, but this pricing puts it in the range of full-featured dev tools that offer significantly more. A one-time purchase (of devices up to that point) or a much lower subscription (2-3€/month) would be far more reasonable and likely attract more paying users.
