Here’s a list of ones you (likely) don’t know about:
Netsurf: I’ve only really used it on plan9 but it’s light weight and works ok for basic JavaScript. They have their own layout and JS engine
nyxt: browser written and configured in Common Lisp, it uses WebKit
surf: suckless browser that also uses WebKit
Ladybird, it’s not ready yet but it’s in very active development, writing their own browser engine from scratch
Mothra: the default web browser for 9front. It ignores all JavaScript and most html and css tags making is super fast and secure.
And now I’m crying
