<p><code>zrok</code> supports <code>public</code> sharing for web-based (HTTP and HTTPS) resources. These resources are easily shared with the general internet through public access points.</p>
<h2 class="anchor anchorWithStickyNavbar_LWe7" id="peer-to-public">Peer to Public<a href="#peer-to-public" class="hash-link" aria-label="Direct link to Peer to Public" title="Direct link to Peer to Public"></a></h2>
<p><img decoding="async" loading="lazy" alt="zrok_public_share" src="/assets/images/zrok_public_share-1eec22cb798395c2bcd3ac10465f62ca.png" width="2200" height="916" class="img_ev3q"></p>
<p><code>public</code> sharing is most useful when the person or service accessing your resources does not have <code>zrok</code> running locally and cannot make use of the <code>private</code> sharing mode built into <code>zrok</code>. Many users share development web servers, webhooks, and other HTTP/HTTPS resources.</p>
<p>As with <code>private</code> sharing, <code>public</code> sharing does not require you to open any firewall ports or otherwise compromise the security of your local environments. A <code>public</code> share goes away as soon as you terminate the <code>zrok share</code> command.</p>
<p>Using <code>public</code> shares is easy and is accomplished using the <code>zrok share public</code> command. Run <code>zrok share public</code> to see the command-line help and to learn how to use <code>public</code> shares.</p>
<h2 class="anchor anchorWithStickyNavbar_LWe7" id="public-backend-modes">Public Backend Modes<a href="#public-backend-modes" class="hash-link" aria-label="Direct link to Public Backend Modes" title="Direct link to Public Backend Modes"></a></h2>
<p>The default backend mode is <code>proxy</code> which targets an HTTP URL that must be reachable by the backend.</p>
<div class="language-bash codeBlockContainer_Ckt0 theme-code-block" style="--prism-color:#F8F8F2;--prism-background-color:#282A36"><div class="codeBlockTitle_OeMC">proxy example</div><div class="codeBlockContent_QJqH"><pre tabindex="0" class="prism-code language-bash codeBlock_bY9V thin-scrollbar" style="color:#F8F8F2;background-color:#282A36"><code class="codeBlockLines_e6Vv"><span class="token-line" style="color:#F8F8F2"><span class="token plain">zrok share public 80</span><br></span></code></pre></div></div>
<ul>
<li><code>proxy</code> mode forwards requests received by the frontend to the target server (<a href="/docs/concepts/http/">more</a>)</li>
<li><code>web</code> mode serves a target folder as a file index web page (<a href="/docs/concepts/files/">more</a>)</li>
<li><code>drive</code> mode serves a target folder with WebDAV (<a href="/docs/guides/drives/">guide</a>)</li>
<li><code>caddy</code> mode runs the built-in Caddy server with the targeted Caddyfile (<a href="/simple_reverse_proxy.Caddyfile" target="_blank" rel="noopener noreferrer">example</a>)</li>
