Internet Browser (unconfirmed) is a web browser preloaded on the Nintendo Switch. It is presumably based on Webkit.
The browser functionality is not accessible to the user, since there is no app for it. However, it can be accessed via an exploit. When linking the Nintendo Account with Facebook, the Facebook Auth website will open, offering a search box that can be used to browse the internet.
