A developer named Blue Edge has created a Windows 11 inside a browser simulation dubbed "Windows 11 in React" using ReactJS, SCSS, CSS. The website allows you to experience what the GUI of the home screen in the next-gen OS looks like to a very limited degree. For example, you can do some basic interaction on it, like launching the Start menu, opening the Edge browser, launching the Microsoft Store, and more.
Interestingly, when you try to run the File Explorer inside Blue Edge's Windows 11 in React, it opens up to a "Coming Soon" webpage indicating that perhaps more additions will be made to it later although it will still most likely be a limited experience since there is only so much one can do to simulate an entire OS as big as Windows 11 within a browser.
Overall, it looks like a fun little toy to play around with but do not expect to be wooed away by it in comparison to what it's like to have the actual full OS experience. For those interested, you can try the Windows 11 in React by Blue Edge through the following link: https://win11.blueedge.me
