Cast Chrome desktop browser tab to Android device I want to mirror the content from a Chrome desktop tab on my Android device.
Is it possible to cast a Chrome browser tab from desktop to an Android (OS 8.1) device?
You can install WebRTC Desktop Sharing extension on your Chrome browser for Desktop. Click on its icon &rarr; Chrome tab + Speakers &rarr; choose your tab to share &rarr; wait for the extension to give you a URL.

Use that URL into your Android device's browser. It will take few seconds to initialize everything and then you can have a real-time Chrome tab sharing from Desktop to anywhere. 

Alternatively, if you are using Windows, enable Remote Desktop Sharing in it, setup a Remote Desktop connection and use Chrome Remote Desktop app to share the whole screen with Android. I haven't tested this one though.
