this is a really cool browser, it's web engine agnostic so it supports webkit and blink depending on what you want, it's keyboard driven (which unfortunately as someone that doesn't use vim or any of the other cool kid layouts is very hard to get used to), it's also super customizable and has it's own extensions written in lisp that remind me a bit of firefoxes XUL addons, with webextensions as a planned feature. It's available for Linux, MacOS, and BSD (and windows unofficially using WSL)
I am a big emacs evil-mode user and this looks really cool to me. Being able to open this in a emacs buffer would be amazing.
