Unofficial Python port of puppeteer JavaScript (headless) chrome/chromium browser automation library.

Unofficial Python port of puppeteer JavaScript (headless) chrome/chromium browser automation library.

Pyppeteer is mostly used for:

  1. Generate screenshots and PDFs of pages.
  2. Crawl an SPA and generate pre-rendered content (i.e. "SSR").
  3. Scrape content from websites.
  4. Automate form submission, UI testing, keyboard input, etc.
  5. Create an up-to-date, automated testing environment. Run your tests directly in the latest version of Chrome using the latest JavaScript and browser features.
  6. Capture a timeline trace of your site to help diagnose performance issues.
