Is there a modern version of lynx/links using an engine like WebKit? I always thought this would be useful but must admit I never got around to writing it.
Browsh[0] might come close to what you’re looking for. It’s not strictly designed to be less memory or faster - better for bringing up a browser on a remote system as it still uses a headless instance of Firefox behind the scenes.
It depends by what you mean. Do you mean Command line accessible version? If so, there are several that work in terminals. Do you mean text only? If so, there are several browsers that can do this for you :-)
Care to provide some working examples? Many that can be found on Google appear to be working prototypes that are not actually usable.
Depends on your idea of "usable" of course:), but w3m?
