<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 &quot;md&quot; 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>

<h5 id="install-with-prebuilt-binaries">Install with prebuilt binaries</h5>
<p>You can find prebuilt binaries <a href="https://github.com/torappinfo/ebrowser/releases">here</a>.</p>
<h5 id="install-with-nodejs">Install with nodejs</h5>
<pre><code>npm install electron
npm install ebrowser
</code></pre>
<p>Run ebrowser</p>
<pre><code>electron ~/node_modules/ebrowser
</code></pre>
<p>Later on, you can run &quot;npm install electron&quot; to update electron/chromium or &quot;npm install ebrowser&quot; to update ebrowser independently.</p>

<p>Like any popular browser, the very first word in address bar if defined in &quot;search.json&quot; identifies a search engine. Moreover, the address bar serves as command line interface:</p>
<ul>

<li>&quot;:&quot; for address bar commands
<ul>
<li>ac [bookmark/history path w/o ext] : load &quot;.rec&quot; file for autocomplete.</li>
<li>b [bookmarkfilename w/o ext] : bookmark current page in file.</li>
