Puppeteer is a Node library that provides a high-level API to control Chrome or Chromium over the DevTools Protocol. It allows automation of tasks such as generating screenshots, crawling websites to capture pre-rendered content, automating form submissions and UI testing, and capturing performance traces. Puppeteer runs Chrome/Chromium in a headless environment by default but can also run the full browser if needed.
