Dillo is a web browser with no JavaScript support, it also has basic CSS support, and even a plugin for the Gopher Protocol! It is written in C and C++ with a few dependancies, has it's own real-time rendering engine, supports HTTP, HTTPi, HTTPS, FTP and local files by default. It is, blazingly fast, even with very large pages, it is small and uses very low amounts of memory. Basically it is very "Unbloated" if you know what I mean. It's the go to browser for when I want to browse pages that don't have or opt-out for JavaScript, plus having your own CSS is great, I can configure the colors and fonts of almost everything. Honestly I think more people should have an opt-out for JavaScript. Dillo is also great if you have a slow connection or old hardware, it's also cross-platform, you can even run it on an Atari for fucks sake. Oh and speaking about the plugins, you can easily write your own plugins for it, most plugins are just a few lines of shell scripts, so you can easily just read a few of the plugins they have and write your own for it. It's awesome!
You can git clone their latest version from:

I use Dillo in my daily life a lot, even right now to see how the page looks while I am writing it. I mean it's free, it's licensed under GPLv3, what more can you want?
