It's not quite the same but since Emacs is primarily an OS it has window managements build in, so by running it fullscreen and making a bunch of horizontal and vertical splits you get pretty close to i3[1] as well.
The only problem is terminals. You can run them inside of Emacs, but there's always issues. You can run eshell[2] which is wonderful. Myself, I prefer to use terminals outside of Emacs.
