What Scrapling does

Scrapling is a robust web scraping framework designed for developers and researchers who need to extract data from websites while navigating around common anti-bot measures. With its advanced features, Scrapling allows users to scrape static HTML pages, dynamically rendered JavaScript content, and even bypass Cloudflare's protective barriers. The framework supports multiple fetching strategies, including HTTP for fast bulk requests, dynamic fetching for single-page applications, and stealth mode for sites with stringent bot detection.

The tool is built on Python and Bash, providing a command-line interface (CLI) that simplifies the scraping process. Users can easily extract data using CSS selectors or XPath, and the output can be customized in various formats such as HTML, Markdown, or JSON. Scrapling also includes a spider framework for crawling multiple pages, making it suitable for larger scraping tasks. The library's flexibility allows developers to switch between different fetching strategies based on the requirements of the target site.

Scrapling is particularly useful for educational and research purposes, where compliance with local data scraping laws is essential. Users are encouraged to respect the terms of service of the websites they scrape. The framework is ideal for those who find built-in web extraction tools insufficient for their needs, as it offers more control and capabilities for complex scraping scenarios.

When to use it

Use Scrapling when you need to scrape data from static or JavaScript-rendered web pages, especially when facing Cloudflare protection or other bot detection systems.

When not to use it

This tool may not be suitable for simple scraping tasks where built-in tools suffice, or for users who do not comply with data scraping regulations.

What you can build with it

Scraping Static Websites

Use Scrapling to quickly extract data from static HTML pages, which is faster than using browser-based tools.

Bypassing Cloudflare

Utilize Scrapling's stealth mode to scrape data from websites protected by Cloudflare or other anti-bot measures.

Crawling Multiple Pages

Employ Scrapling's spider framework to efficiently crawl and scrape data from multiple interconnected web pages.

Scrapling

Scrapling is a web scraping framework with anti-bot bypass, stealth browser automation, and a spider framework. It provides three fetching strategies (HTTP, dynamic JS, stealth/Cloudflare) and a full CLI.

This skill is for educational and research purposes only. Users must comply with local/international data scraping laws and respect website Terms of Service.

When to Use

  • Scraping static HTML pages (faster than browser tools)
  • Scraping JS-rendered pages that need a real browser
  • Bypassing Cloudflare Turnstile or bot detection
  • Crawling multiple pages with a spider
  • When the built-in web_extract tool does not return the data you need

Installation

pip install "scrapling[all]"
scrapling install

Minimal install (HTTP only, no browser):

pip install scrapling

With browser automation only:

pip install "scrapling[fetchers]"
scrapling install

Quick Reference

ApproachClassUse When
HTTPFetcher / FetcherSessionStatic pages, APIs, fast bulk requests
DynamicDynamicFetcher / DynamicSessionJS-rendered content, SPAs
StealthStealthyFetcher / StealthySessionCloudflare, anti-bot protected sites
SpiderSpiderMulti-page crawling with link following

CLI Usage

Extract Static Page

scrapling extract get 'https://example.com' output.md

With CSS selector and browser impersonation:

scrapling extract get 'https://example.com' output.md \
  --css-selector '.content' \
  --impersonate 'chrome'

Extract JS-Rendered Page

scrapling extract fetch 'https://example.com' output.md \
  --css-selector '.dynamic-content' \
  --disable-resources \
  --network-idle

Extract Cloudflare-Protected Page

scrapling extract stealthy-fetch 'https://protected-site.com' output.html \
  --solve-cloudflare \
  --block-webrtc \
  --hide-canvas

POST Request

scrapling extract post 'https://example.com/api' output.json \
  --json '{"query": "search term"}'

Output Formats

The output format is determined by the file extension:

  • .html -- raw HTML
  • .md -- converted to Markdown
  • .txt -- plain text
  • .json / .jsonl -- JSON

Python: HTTP Scraping

Single Request

from scrapling.fetchers import Fetcher

page = Fetcher.get('https://quotes.toscrape.com/')
quotes = page.css('.quote .text::text').getall()
for q in quotes:
    print(q)

Session (Persistent Cookies)

from scrapling.fetchers import FetcherSession

with FetcherSession(impersonate='chrome') as session:
    page = session.get('https://example.com/', stealthy_headers=True)
    links = page.css('a::attr(href)').getall()
    for link in links[:5]:
        sub = session.get(link)
        print(sub.css('h1::text').get())

POST / PUT / DELETE

page = Fetcher.post('https://api.example.com/data', json={"key": "value"})
page = Fetcher.put('https://api.example.com/item/1', data={"name": "updated"})
page = Fetcher.delete('https://api.example.com/item/1')

With Proxy

page = Fetcher.get('https://example.com', proxy='http://user:pass@proxy:8080')

Python: Dynamic Pages (JS-Rendered)

For pages that require JavaScript execution (SPAs, lazy-loaded content):

from scrapling.fetchers import DynamicFetcher

page = DynamicFetcher.fetch('https://example.com', headless=True)
data = page.css('.js-loaded-content::text').getall()

Wait for Specific Element

page = DynamicFetcher.fetch(
    'https://example.com',
    wait_selector=('.results', 'visible'),
    network_idle=True,
)

Disable Resources for Speed

Blocks fonts, images, media, stylesheets (~25% faster):

from scrapling.fetchers import DynamicSession

with DynamicSession(headless=True, disable_resources=True, network_idle=True) as session:
    page = session.fetch('https://example.com')
    items = page.css('.item::text').getall()

Custom Page Automation

from playwright.sync_api import Page
from scrapling.fetchers import DynamicFetcher

def scroll_and_click(page: Page):
    page.mouse.wheel(0, 3000)
    page.wait_for_timeout(1000)
    page.click('button.load-more')
    page.wait_for_selector('.extra-results')

page = DynamicFetcher.fetch('https://example.com', page_action=scroll_and_click)
results = page.css('.extra-results .item::text').getall()

Python: Stealth Mode (Anti-Bot Bypass)

For Cloudflare-protected or heavily fingerprinted sites:

from scrapling.fetchers import StealthyFetcher

page = StealthyFetcher.fetch(
    'https://protected-site.com',
    headless=True,
    solve_cloudflare=True,
    block_webrtc=True,
    hide_canvas=True,
)
content = page.css('.protected-content::text').getall()

Stealth Session

from scrapling.fetchers import StealthySession

with StealthySession(headless=True, solve_cloudflare=True) as session:
    page1 = session.fetch('https://protected-site.com/page1')
    page2 = session.fetch('https://protected-site.com/page2')

Element Selection

All fetchers return a Selector object with these methods:

CSS Selectors

page.css('h1::text').get()              # First h1 text
page.css('a::attr(href)').getall()      # All link hrefs
page.css('.quote .text::text').getall() # Nested selection

XPath

page.xpath('//div[@class="content"]/text()').getall()
page.xpath('//a/@href').getall()

Find Methods

page.find_all('div', class_='quote')       # By tag + attribute
page.find_by_text('Read more', tag='a')    # By text content
page.find_by_regex(r'\$\d+\.\d{2}')       # By regex pattern

Similar Elements

Find elements with similar structure (useful for product listings, etc.):

first_product = page.css('.product')[0]
all_similar = first_product.find_similar()

Navigation

el = page.css('.target')[0]
el.parent                # Parent element
el.children              # Child elements
el.next_sibling          # Next sibling
el.prev_sibling          # Previous sibling

Python: Spider Framework

For multi-page crawling with link following:

from scrapling.spiders import Spider, Request, Response

class QuotesSpider(Spider):
    name = "quotes"
    start_urls = ["https://quotes.toscrape.com/"]
    concurrent_requests = 10
    download_delay = 1

    async def parse(self, response: Response):
        for quote in response.css('.quote'):
            yield {
                "text": quote.css('.text::text').get(),
                "author": quote.css('.author::text').get(),
                "tags": quote.css('.tag::text').getall(),
            }

        next_page = response.css('.next a::attr(href)').get()
        if next_page:
            yield response.follow(next_page)

result = QuotesSpider().start()
print(f"Scraped {len(result.items)} quotes")
result.items.to_json("quotes.json")

Multi-Session Spider

Route requests to different fetcher types:

from scrapling.fetchers import FetcherSession, AsyncStealthySession

class SmartSpider(Spider):
    name = "smart"
    start_urls = ["https://example.com/"]

    def configure_sessions(self, manager):
        manager.add("fast", FetcherSession(impersonate="chrome"))
        manager.add("stealth", AsyncStealthySession(headless=True), lazy=True)

    async def parse(self, response: Response):
        for link in response.css('a::attr(href)').getall():
            if "protected" in link:
                yield Request(link, sid="stealth")
            else:
                yield Request(link, sid="fast", callback=self.parse)

Pause/Resume Crawling

spider = QuotesSpider(crawldir="./crawl_checkpoint")
spider.start()  # Ctrl+C to pause, re-run to resume from checkpoint

Pitfalls

  • Browser install required: run scrapling install after pip install -- without it, DynamicFetcher and StealthyFetcher will fail
  • Timeouts: DynamicFetcher/StealthyFetcher timeout is in milliseconds (default 30000), Fetcher timeout is in seconds
  • Cloudflare bypass: solve_cloudflare=True adds 5-15 seconds to fetch time -- only enable when needed
  • Resource usage: StealthyFetcher runs a real browser -- limit concurrent usage
  • Legal: always check robots.txt and website ToS before scraping. This library is for educational and research purposes
  • Python version: requires Python 3.10+
