Cloudflare’s a pain, but you can bypass it with playwright or selenium—just slower.

For proxies, I rotate with ProxyCrawl. Works decently.

Scrapy’s the best for large-scale python web crawler, but if it’s too much, try httpx + asyncio. Less magic, more control.

Oh, and always respect robots.txt. Unless you’re feeling risky lol.
