47 <p>Ebrowser is designed with the philosophy of
<a href=
"https://github.com/torappinfo/uweb">Android uweb browser
</a> (
<a href=
"https://gitlab.com/jamesfengcao/uweb">gitlab
</a>).
</p>
49 <li>lightweight (less than
20k bytes) without bundled electron.
</li>
50 <li>much less memory footprint than edge/chrome browser and highly performant.
</li>
51 <li>keyboard friendly with vim-style keymaps and command line support in address bar.
</li>
52 <li><a href=
"https://uweb.surge.sh/en/redirect/index.html#">global redirection
</a> to bypass censorship.
</li>
53 <li>user CSS/JS at will. Ex. pressing
"md
" in no-focus mode to preview markdown file.
</li>
54 <li>global CSS/JS for all sites at will.
</li>
55 <li>CSS/JS for domains, similar to
<a href=
"https://jamesfengcao.gitlab.io/uweb/en/sitejs/index.html">uweb
</a>, but use sitejs/[domain].js or sitecss/[domain].css, not [domain root].js/css.
</li>
56 <li>customizable.
</li>
58 <p>Note: Usually electron apps are heavyweight as they use browsers for simple things. Ebrowser uses core chromium effectively and very lightweight. Recommend to install electron separately.
