Chrome/Chromium over the

Puppeteer runs in
<a href="https://developer.chrome.com/articles/new-headless/" target="_blank" rel="noopener noreferrer">headless</a>
mode by default, but can be configured to run in full (&quot;headful&quot;)
Chrome/Chromium.</p></blockquote><h4 class="anchor anchorWithStickyNavbar_LWe7" id="what-can-i-do">What can I do?<a href="#what-can-i-do" class="hash-link" aria-label="Direct link to What can I do?" title="Direct link to What can I do?">​</a></h4><p>Most things that you can do manually in the browser can be done using Puppeteer!
Here are a few examples to get you started:</p><ul><li>Generate screenshots and PDFs of pages.</li><li>Crawl a SPA (Single-Page Application) and generate pre-rendered content (i.e.
&quot;SSR&quot; (Server-Side Rendering)).</li><li>Automate form submission, UI testing, keyboard input, etc.</li><li>Create an automated testing environment using the latest JavaScript and
browser features.</li><li>Capture a

by default (starting with Puppeteer v19.0.0).</p><p>If you deploy a project using Puppeteer to a hosting provider, such as Render or
Heroku, you might need to reconfigure the location of the cache to be within
your project folder (see an example below) because not all hosting providers
include <code>$HOME/.cache</code> into the project&#x27;s deployment.</p><p>For a version of Puppeteer without the browser installation, see
<a href="#puppeteer-core"><code>puppeteer-core</code></a>.</p><p>If used with TypeScript, the minimum supported TypeScript version is <code>4.7.4</code>.</p><h4 class="anchor anchorWithStickyNavbar_LWe7" id="configuration">Configuration<a href="#configuration" class="hash-link" aria-label="Direct link to Configuration" title="Direct link to Configuration">​</a></h4><p>Puppeteer uses several defaults that can be customized through configuration
files.</p><p>For example, to change the default cache directory Puppeteer uses to install
