Viewport Resizer: Ultimate Device Emulator & Website Testing Tool

A very reliable tool. These other reviews are harsh lol! There is plenty of functionality + room for configs, which is difficult to find without being harassed for subscriptions. Respect! (it does work on localhost for anybody wondering about the previous review)

Sometimes work but most of the time it's not even start only showing a status on extension icon as on but nothing happening and in localhost not working at all

The best

If it doesn't work on localhost it makes no sense at all. This is supposed to be a developer tool, I need it to work when I'm developing.

Good, but like many of this kind of tools it need to be updated with new resolutions for mobile. Right now you can look at iPhone 5 to 8 when their is iPhone 15 Pro Max out on market

Good - but flawed. It doesn't refresh the page as you navigate, and just seemingly springs back to full resolution whenever it likes. Also you can't save your custom resolutions.

not work in localhost web, need to be hosted.Tried www.responsinator.com/, better and you can test for localhost

Easy, working, but one type with an example on different screen sizes would be great, like material.io had (though their Resizer tool isn't working at all, bad stuff)

This extension has saved my life. Literally. Recently, our workplace website was upgraded and this new site could no way be adjusted to a mobile screen display. But by using Kiwi browser + this extenion, I did get what I wanted. An thereby could avoid the purcahse of a tablet!

Too bad it doesn't work for local files. I wanted to use it as a dev tool...
