Rabbit

Rabbit allows you and friends to watch videos and browse the internet together in a hosted browser, which provides a different experience. Listed here are multiple voice/video chat options. While rabbit does allow this kind of communication, none of these other options are quite the same. As far as i'm aware, there really isn't anything quite like rabbit at this point in time, with the project itself still in beta.

Their newest update has removed nearly all of the features listed here, Netflix does not work, you can't change quality, most buttons and controls are gone and it looks like trash,

It is the only thing I know of in it's category. Have used it both to watch things with my friends and as a proxy.

It really hurts me to see rabb.it go away. I had been on rabb.it for a very long time. More than 4 years I guess! It's a great service. I met great friends there. Spent hours and hours watching videos talking to friends and curating relationships that I value the most. I wish rabb.it would've stayed as long as those relationships are staying that it helped me made! GoodLuck team Rabb.it.

Rabb.it is discontinued, but it's been reworked as Kast.
