What is Scrapling in Python?

Scrapling is a Python 3.10+ web scraping framework that wraps three fetching backends behind one consistent selector API: plain HTTP with TLS fingerprint impersonation, a stealth-mode anti-detection browser, and a full Playwright-driven browser. It combines Scrapy-style spidering, curl_cffi-style TLS fingerprinting, and an undetected Playwright in a single import.

What are the three fetchers in Scrapling and when do you use each?

Fetcher uses plain HTTP with TLS fingerprint impersonation for fast static HTML scraping. StealthyFetcher uses a headless browser with anti-detection patches for Cloudflare or JS-protected pages. DynamicFetcher uses Playwright/Chromium for full automation of SPAs with complex auth or click flows. A single Spider class can mix tiers per request.

Is Scrapling actually faster than Scrapy and BeautifulSoup?

Scrapling is roughly 784x faster than BeautifulSoup4 (1584 ms vs ~2 ms parsing 5,000 nested elements), but that gap is a known lxml-vs-BS4 result, not unique to Scrapling. Against Scrapy's Parsel engine it is within margin of error (2.02 ms vs 2.04 ms). Its real-world advantage is at the network layer, where TLS fingerprint impersonation can skip spinning up a browser.

How do you install Scrapling's StealthyFetcher for Cloudflare pages?

Run pip install "scrapling[fetchers]" followed by scrapling install. The scrapling install step downloads patched Chromium binaries, which is a couple hundred MB of dependencies, so be aware of that before installing on a small VM.

Does Scrapling respect robots.txt by default?

No. The robots_txt_obey setting is opt-in, not on by default, so you must consciously enable it. This is a deliberate choice for users who own the sites they crawl, but forgetting to turn it on for a third-party site can create legal exposure.

Scrapling 评测：一种更快、更隐蔽的 Python 爬取方式

大致有四个 Python 网络爬虫的时代。

urllib 和正则表达式。

然后，当网站一半变成仅限 JavaScript 时，Playwright
