Browser Run - Introducing Kitesurf, an agent-first browser on Browser Run

<p><a href="https://developers.cloudflare.com/browser-run/kitesurf/">Kitesurf</a> is Cloudflare's new stateless, highly scalable browser that runs entirely on top of <a href="https://developers.cloudflare.com/workers/">Workers</a> and is designed for AI agents. It is available for free while in beta.</p> <p>Compared to Chromium, Kitesurf uses 3–7× less CPU and memory for common agentic tasks like screenshots and HTML extraction, so you can run more sessions and scale better for bursty, AI-driven workloads.</p> <p>Your existing clients already work. To opt in, add the <code>browser=kitesurf</code> parameter to any Browser Run <a href="https://developers.cloudflare.com/browser-run/cdp/">CDP</a> or <a href="https://developers.cloudflare.com/browser-run/quick-actions/">Quick Action</a> endpoint:</p> <figure class="nb-code-figure" data-nb-lang="sh"><pre class="astro-code astro-code-themes github-light github-dark nb-shiki-c6xiwz" tabindex="0" data-language="sh" data-nb-lang="sh"><code><span class="line"><span class="nb-shiki-1t8gfj">curl</span><span class="nb-shiki-dzsirb"> -X</span><span class="nb-shiki-mdbnqw"> POST</span><span class="nb-shiki-mdbnqw"> 'https://api.cloudflare.com/client/v4/accounts/&lt;ACCOUNT_ID&gt;/browser-run/screenshot?browser=kitesurf'</span><span class="nb-shiki-dzsirb"> \</span></span> <span class="line"><span class="nb-shiki-dzsirb"> -H</span><span class="nb-shiki-mdbnqw"> 'Authorization: Bearer &lt;API_TOKEN&gt;'</span><span class="nb-shiki-dzsirb"> \</span></span> <span class="line"><span class="nb-shiki-dzsirb"> -H</span><span class="nb-shiki-mdbnqw"> 'Content-Type: application/json'</span><span class="nb-shiki-dzsirb"> \</span></span> <span class="line"><span class="nb-shiki-dzsirb"> -d</span><span class="nb-shiki-mdbnqw"> '{</span></span> <span class="line"><span class="nb-shiki-mdbnqw"> "url": "https://example.com"</span></span> <span class="line"><span class="nb-shiki-mdbnqw"> }'</span><span class="nb-shiki-dzsirb"> \</span></span> <span class="line"><span class="nb-shiki-dzsirb"> --output</span><span class="nb-shiki-mdbnqw"> "screenshot.png"</span></span></code></pre></figure> <p>You can also explore Kitesurf without writing any code in the <a href="https://kitesurf.cloudflare.app/" target="_blank" rel="noopener">public playground<span class="external-link"> ↗︎</span></a>.</p> <p>For more information, refer to the <a href="https://developers.cloudflare.com/browser-run/kitesurf/">Kitesurf documentation</a> and the <a href="https://blog.cloudflare.com/kitesurf" target="_blank" rel="noopener">blog announcement<span class="external-link"> ↗︎</span></a>.</p>
