Default runtime settings
1. Uses Headless mode
Puppeteer launches Chromium in headless mode. To launch a full version of Chromium, set the 'headless' option when launching a browser:
const browser = await puppeteer.launch({headless: false}); // default is true
2. Runs a bundled version of Chromium
By default, Puppeteer downloads and uses a specific version of Chromium so its API is guaranteed to work out of the box. To use Puppeteer with a different version of Chrome or Chromium, pass in the executable's path when creating a Browser instance:
const browser = await puppeteer.launch({executablePath: '/path/to/Chrome'});
See Puppeteer.launch() for more information.
See this article for a description of the differences between Chromium and Chrome. This article describes some differences for Linux users.
3. Creates a fresh user profile
Puppeteer creates its own Chromium user profile which it cleans up on every run.
