Hi Sanket, If you are looking for a way to check how your website looks in different browsers (including mobile), checkout https://dev.windows.com/en-us/microsoft-edge/tools/screenshots/[^] and enter the public version of your web address. Also, you can load your webapp in mobile browser to test it. If you don't have the required device, you can install the Visual Studio Community Edition (FREE)[^] and try directly in the emulator. Hope this helps.
