Should I use Playwright for large-scale crawling?

Sometimes — but not as your first choice if you can avoid it.

Use Playwright for large-scale crawling when:

• The site requires JavaScript to render important content
• There are anti-bot measures that simple HTTP requests can’t handle
• You need to interact with the page:
  • click buttons
  • scroll for lazy-loaded content
  • fill forms / log in
• The target pages are few enough that browser overhead is acceptable

Avoid Playwright when:

• The content is available in the HTML or via an API
• You need to crawl millions of pages efficiently
• Speed, cost, and reliability matter more than full page rendering

Why not for huge-scale crawling?

Playwright is a real browser automation tool, so it’s:

• Slower than plain HTTP scraping
• More resource-heavy in CPU/RAM
• Harder to scale to many concurrent pages
• More likely to run into browser stability issues at very high volume

Better pattern for large-scale crawling

A common approach is:

1. Use HTTP requests / crawler framework for most pages
2. Use Playwright only for pages that need it

This hybrid strategy is usually the best of both worlds.

Practical rule of thumb

• Static or API-backed pages: use requests/HTTP scraping
• JS-heavy or interactive pages: use Playwright
• Very large-scale crawling: prefer a hybrid architecture, not Playwright everywhere

If you want, I can help you choose between Playwright, Scrapy, Puppeteer, or raw HTTP based on your specific crawl size and target site.
