|
|
<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>
|
|
<ul>
|
|
<li>lightweight (less than 20k bytes) without bundled electron.</li>
|
|
<li>much less memory footprint than edge/chrome browser and highly performant.</li>
|
|
<li>keyboard friendly with vim-style keymaps and command line support in address bar.</li>
|
|
<li><a href="https://uweb.surge.sh/en/redirect/index.html#">global redirection</a> to bypass censorship.</li>
|
|
<li>user scripts at will. Ex. pressing "md" in no-focus mode to preview markdown file.</li>
|
|
<li>customizable.</li>
|
|
</ul>
|
|
<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.</p>
