Playwright enables parallel browser automation for faster scraping
Playwright supports running multiple browser instances in parallel using Python threads or async, reducing scraping time from 60 seconds to 10 seconds. Each browser process uses 200-400 MB of RAM, and developers must handle rate limiting and resource cleanup. The technique is useful for web scraping and cross-browser testing at scale.
