What is Playwright for web scraping?
Playwright is a browser automation library by Microsoft that controls Chromium, Firefox, and WebKit programmatically. Unlike requests, which only fetches raw HTML, Playwright runs a real headless browser, executing JavaScript, handling logins, clicking buttons, and waiting for dynamically rendered content before extraction.
| Factor | Playwright | Requests + BeautifulSoup |
|---|---|---|
| JS rendering | ✓ Full browser execution | ✗ Raw HTML only |
| Memory usage | High (browser process per session) | Minimal |
| Setup complexity | High: browser install, async handling | Simple |
| Interactive flows | Login, pagination, clicks | Not supported |
| Maintenance | Breaks when selectors or JS changes | Breaks when HTML structure changes |
Use Playwright when your target site renders content with JavaScript, requires authentication, or needs multi-step interactions like infinite scroll or form submissions. For static pages at high volume, it's overkill: the browser overhead slows requests and consumes significant memory. For how it stacks up against Puppeteer, see Playwright vs Puppeteer.
The most common production issues with Playwright are memory leaks in long-running processes and fragile selectors that break when sites update. Firecrawl's Scrape API handles JavaScript rendering, proxy rotation, and anti-bot mechanisms without running or managing Playwright yourself.
