Headless Browser
A headless browser is a web browser that runs without a graphical user interface.
It executes JavaScript, renders CSS, and simulates user interactions just like a real browser — but without displaying anything on screen. Headless Chrome (via Playwright or Puppeteer) is the standard for scraping JavaScript-heavy websites.
