This is a list of light web browsers, most running their own engine. We need alternatives in the face of an imminent monopoly. We need software that can run on old computers. A simpler web that's easier to understand and won't readily turn against us.
Lynx is the text-based browser everyone's heard about. It's more than that however: comes with Gopher support and a file manager built right in, among other things. It also helpfully colors web pages according to markup, which lends it a distinctive look.
By contrast, Links2 is more and less at the same time. It's only a web browser, but more friendly than Lynx. Plus, it can also run in graphical mode and even show images (not all popular formats).
Moving on, NetSurf is a graphical browser that targets older web standards. Modern web pages can confuse it. Things are getting better, but slowly.
At the high end of alternatives, QuteBrowser uses an almost mainstream engine, so in principle it can open most websites, but still not all of them. It's also pretty hardcore, with a minimal user interface that's mostly keyboard-driven and sometimes lags.
Last but not least, Kristall mainly aims to support the Gopher and Gemini protocols, but can also render web pages. Being able to browse them all can come in handy.
All these browsers run on Linux and Haiku at the very least. There are others, too. What we need is more websites that work in them, even partially.
