Setup (once)
Create a virtual Python environment through any way available, like venv, then inside the environment do:
pip install "scrapling[all]>=0.4.8"
Then do this to download all the browsers' dependencies:
scrapling install --force
Make note of the scrapling binary path and use it instead of scrapling from now on with all commands (if scrapling is not on $PATH).
Docker
Another option if the user doesn't have Python or doesn't want to use it is to use the Docker image, but this can be used only in the commands, so no writing Python code for scrapling this way:
docker pull pyd4vinci/scrapling
or
docker pull ghcr.io/d4vinci/scrapling:latest
CLI Usage
The scrapling extract command group lets you download and extract content from websites directly without writing any code.
Usage: scrapling extract [OPTIONS] COMMAND [ARGS]...
Commands:
get Perform a GET request and save the content to a file.
post Perform a POST request and save the content to a file.
put Perform a PUT request and save the content to a file.
delete Perform a DELETE request and save the content to a file.
fetch Use a browser to fetch content with browser automation and flexible options.
stealthy-fetch Use a stealthy browser to fetch content with advanced stealth features.
Usage pattern
- Choose your output format by changing the file extension. Here are some examples for the
scrapling extract getcommand:
- Convert the HTML content to Markdown, then save it to the file (great for documentation):
scrapling extract get "https://blog.example.com" article.md
- Save the HTML content as it is to the file:
scrapling extract get "https://example.com" page.html
- Save a clean version of the text content of the webpage to the file:
scrapling extract get "https://example.com" content.txt
- Output to a temp file, read it back, then clean up.
- All commands can use CSS selectors to extract specific parts of the page through
--css-selectoror-s.
Which command to use generally:
- Use **
get** with simple websites, blogs, or news articles.
- Use **
fetch** with modern web apps, or sites with dynamic content.
- Use **
stealthy-fetch** with protected sites, Cloudflare, or anti-bot systems.
When unsure, start with get. If it fails or returns empty content, escalate to fetch, then stealthy-fetch. The speed of fetch and stealthy-fetch is nearly the same, so you are not sacrificing anything.

Notes
- ALWAYS clean up temp files after reading
- Prefer
.mdoutput for readability; use.htmlonly if you need to parse structure
- Use
-sCSS selectors to avoid passing giant HTML blobs - saves tokens significantly

Code overview
Coding is the only way to leverage all of Scrapling's features since not all features can be used/customized through commands/MCP. Here's a quick overview of how to code with scrapling.
Basic Usage
HTTP requests with session support
from scrapling.fetchers import Fetcher, FetcherSession
with FetcherSession(impersonate='chrome') as session: # Use latest version of Chrome's TLS fingerprint
page = session.get('https://quotes.toscrape.com/', stealthy_headers=True)
quotes = page.css('.quote .text::text').getall()
# Or use one-off requests
page = Fetcher.get('https://quotes.toscrape.com/')
quotes = page.css('.quote .text::text').getall()
Advanced stealth mode
from scrapling.fetchers import StealthyFetcher, StealthySession
with StealthySession(headless=True, solve_cloudflare=True) as session: # Keep the browser open until you finish
page = session.fetch('https://nopecha.com/demo/cloudflare', google_search=False)
data = page.css('#padded_content a').getall()
# Or use one-off request style, it opens the browser for this request, then closes it after finishing
page = StealthyFetcher.fetch('https://nopecha.com/demo/cloudflare')
data = page.css('#padded_content a').getall()
Full browser automation
from scrapling.fetchers import DynamicFetcher, DynamicSession
with DynamicSession(headless=True, disable_resources=False, network_idle=True) as session: # Keep the browser open until you finish
page = session.fetch('https://quotes.toscrape.com/', load_dom=False)
data = page.xpath('//span[@class="text"]/text()').getall() # XPath selector if you prefer it
# Or use one-off request style, it opens the browser for this request, then closes it after finishing
page = DynamicFetcher.fetch('https://quotes.toscrape.com/')
data = page.css('.quote .text::text').getall()
Spiders
Build full crawlers with concurrent requests, multiple session types, and pause/resume:
from scrapling.spiders import Spider, Request, Response
class QuotesSpider(Spider):
name = "quotes"
start_urls = ["https://quotes.toscrape.com/"]
concurrent_requests = 10
robots_txt_obey = True # Respect robots.txt rules
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(),
}
next_page = response.css('.next a')
if next_page:
yield response.follow(next_page[0].attrib['href'])
result = QuotesSpider().start()
print(f"Scraped {len(result.items)} quotes")
result.items.to_json("quotes.json")
Use multiple session types in a single spider:
from scrapling.spiders import Spider, Request, Response
from scrapling.fetchers import FetcherSession, AsyncStealthySession
class MultiSessionSpider(Spider):
name = "multi"
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():
# Route protected pages through the stealth session
if "protected" in link:
yield Request(link, sid="stealth")
else:
yield Request(link, sid="fast", callback=self.parse) # explicit callback
Pause and resume long crawls with checkpoints by running the spider like this:
QuotesSpider(crawldir="./crawl_data").start()
Press Ctrl+C to pause gracefully - progress is saved automatically. Later, when you start the spider again, pass the same crawldir, and it will resume from where it stopped.
While iterating on a spider's parse() logic, set development_mode = True on the spider class to cache responses to disk on the first run and replay them on subsequent runs - so you can re-run the spider as many times as you want without re-hitting the target servers. The cache lives in .scrapling_cache/{spider.name}/ by default and can be overridden with development_cache_dir. Don't ship a spider with this enabled.
For rules-based crawls (follow links matching a regex), use CrawlSpider instead of writing the link-extraction loop yourself:
from scrapling.spiders import CrawlSpider, CrawlRule, LinkExtractor
class BlogCrawler(CrawlSpider):
name = "blog"
start_urls = ["https://example.com"]
def rules(self):
return [
CrawlRule(LinkExtractor(allow=r"/posts/"), callback=self.parse_post),
CrawlRule(LinkExtractor(allow=r"/page/\d+/")), # follow pagination, no callback
]
async def parse_post(self, response):
yield {"title": response.css("h1::text").get()}
For sitemap-driven crawls, use SitemapSpider with the same rules() API. It fetches sitemap_urls, descends into sitemap indexes, and dispatches each URL through your rules. Put a robots.txt URL directly in sitemap_urls and the spider extracts each Sitemap: directive from it automatically. See references/spiders/generic-templates.md for the full reference, including LinkExtractor's allow/deny/restrict_css/canonicalize options.
Advanced Parsing & Navigation
from scrapling.fetchers import Fetcher
# Rich element selection and navigation
page = Fetcher.get('https://quotes.toscrape.com/')
# Get quotes with multiple selection methods
quotes = page.css('.quote') # CSS selector
quotes = page.xpath('//div[@class="quote"]') # XPath
quotes = page.find_all('div', {'class': 'quote'}) # BeautifulSoup-style
# Same as
quotes = page.find_all('div', class_='quote')
quotes = page.find_all(['div'], class_='quote')
quotes = page.find_all(class_='quote') # and so on...
# Find element by text content
quotes = page.find_by_text('quote', tag='div')
# Advanced navigation
quote_text = page.css('.quote')[0].css('.text::text').get()
quote_text = page.css('.quote').css('.text::text').getall() # Chained selectors
first_quote = page.css('.quote')[0]
author = first_quote.next_sibling.css('.author::text')
parent_container = first_quote.parent
# Element relationships and similarity
similar_elements = first_quote.find_similar()
below_elements = first_quote.below_elements()
You can use the parser right away if you don't want to fetch websites like below:
from scrapling.parser import Selector
page = Selector("<html>...</html>")
And it works precisely the same way!
Async Session Management Examples
import asyncio
from scrapling.fetchers import FetcherSession, AsyncStealthySession, AsyncDynamicSession
async with FetcherSession(http3=True) as session: # `FetcherSession` is context-aware and can work in both sync/async patterns
page1 = session.get('https://quotes.toscrape.com/')
page2 = session.get('https://quotes.toscrape.com/', impersonate='firefox135')
# Async session usage
async with AsyncStealthySession(max_pages=2) as session:
tasks = []
urls = ['https://example.com/page1', 'https://example.com/page2']
for url in urls:
task = session.fetch(url)
tasks.append(task)
print(session.get_pool_stats()) # Optional - The status of the browser tabs pool (busy/free/error)
results = await asyncio.gather(*tasks)
print(session.get_pool_stats())
# Capture XHR/fetch API calls during page load
async with AsyncDynamicSession(capture_xhr=r"https://api\.example\.com/.*") as session:
page = await session.fetch('https://example.com')
for xhr in page.captured_xhr: # Each is a full Response object
print(xhr.url, xhr.status, xhr.body)

Guardrails (Always)
- Only scrape content you're authorized to access.
- Respect robots.txt and ToS. Use
robots_txt_obey = Trueon spiders to enforce this automatically.
- Add delays (
download_delay) for large crawls.
- Don't bypass paywalls or authentication without permission.
- Never scrape personal/sensitive data.
