Apple TV 4 was launched by the Apple company without a web browser to surf the Internet using the remote control created especially for it, but an application developer made it possible.
In the video clip below you will see the first web browser created especially for Apple TV 4, the application using private APIs to render web content, so it cannot be published in the App Store, but it was unlikely that Apple would accept the application anyway.
As expected, the web browser of Apple TV 4 it is controlled by the Siri remote control created by the Apple company, and pressing the touch surface on the remote control switches from one working mode to another, so you have various control modes.
The first way of working allows controlling the browser using the touchpad as if we were using the screen of an iPhone or an iPad tablet, the second one displaying a cursor that allows us to select various elements in the interface to control the elements.
Although the idea of a browser is interesting, unfortunately it will not be launched in the App Store because it is based on private APIs, so below you have the source from which you can download and install it with Xcode.
