scrapling

Use Scrapling's StealthyFetcher with solve_cloudflare=True to bypass Cloudflare Turnstile and bot detection. Note that solving Cloudflare adds 5-15 seconds per fetch, so enable it only when the target site requires it.

Use DynamicFetcher.fetch() with headless=True to render JS-heavy pages and SPAs. You can wait for specific elements with wait_selector, block resources for speed with disable_resources, or pass a custom page_action function for scrolling and clicking.

Fetcher makes fast HTTP requests for static pages and APIs. DynamicFetcher runs a real browser for JS-rendered content. StealthyFetcher adds anti-fingerprinting and Cloudflare bypass for protected sites, at the cost of higher resource usage.

Browser binaries are not installed by pip alone. You must run scrapling install after pip install "scrapling[all]", otherwise DynamicFetcher and StealthyFetcher will fail because they require a real browser.

Yes, the Spider framework supports pause and resume via checkpoints. Pass crawldir to the spider constructor, press Ctrl+C to pause, and re-run the same command to resume crawling from the saved checkpoint.

StealthyFetcher runs a real browser, so concurrent usage must be limited to control resource consumption. Timeout units also differ: DynamicFetcher and StealthyFetcher use milliseconds while Fetcher uses seconds. Always check robots.txt and site ToS before scraping.
