PlainView

PlainView is an extremely minimal Safari-based web browser. It only functions in full-screen mode but also offers a complete browser experience. No toolbars or menus are ever visible, all control is done via keyboard shortcuts. The browser was originally designed for presentations but I find that it works very well when it comes to isolating the browsing experience and ensuring that it doesn’t stay as an always-open distraction, something I’ve had trouble with.

A great solution when you need to focus on nothing but the web.
