Scrapling

Scrapling is an adaptive Web Scraping framework that handles everything from a single request to a full-scale crawl.

Its parser learns from website changes and automatically relocates your elements when pages update. Its fetchers bypass anti-bot systems like Cloudflare Turnstile out of the box. And its spider framework lets you scale up to concurrent, multi-session crawls with pause/resume and automatic proxy rotation — all in a few lines of Python. One library, zero compromises.

Blazing fast crawls with real-time stats and streaming. Built by Web Scrapers for Web Scrapers and regular users, there's something for everyone.

Requires: Python 3.10+

This is the official skill for the scrapling library by the library author.

Setup (once)

Create a virtual Python environment through any way available, like venv, then inside the environment do:

pip install "scrapling[all]>=0.4.1"

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 get command:
  • 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-selector or -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.

Key options (requests)

Those options are shared between the 4 HTTP request commands:

Option	Input type	Description
-H, --headers	TEXT	HTTP headers in format "Key: Value" (can be used multiple times)
--cookies	TEXT	Cookies string in format "name1=value1; name2=value2"
--timeout	INTEGER	Request timeout in seconds (default: 30)
--proxy	TEXT	Proxy URL in format "http://username:password@host:port"
-s, --css-selector	TEXT	CSS selector to extract specific content from the page. It returns all matches.
-p, --params	TEXT	Query parameters in format "key=value" (can be used multiple times)
--follow-redirects / --no-follow-redirects	None	Whether to follow redirects (default: True)
--verify / --no-verify	None	Whether to verify SSL certificates (default: True)
--impersonate	TEXT	Browser to impersonate. Can be a single browser (e.g., Chrome) or a comma-separated list for random selection (e.g., Chrome, Firefox, Safari).
--stealthy-headers / --no-stealthy-headers	None	Use stealthy browser headers (default: True)

Options shared between post and put only:

Option	Input type	Description
-d, --data	TEXT	Form data to include in the request body (as string, ex: "param1=value1&param2=value2")
-j, --json	TEXT	JSON data to include in the request body (as string)

Examples:

# Basic download
scrapling extract get "https://news.site.com" news.md

# Download with custom timeout
scrapling extract get "https://example.com" content.txt --timeout 60

# Extract only specific content using CSS selectors
scrapling extract get "https://blog.example.com" articles.md --css-selector "article"

# Send a request with cookies
scrapling extract get "https://scrapling.requestcatcher.com" content.md --cookies "session=abc123; user=john"

# Add user agent
scrapling extract get "https://api.site.com" data.json -H "User-Agent: MyBot 1.0"

# Add multiple headers
scrapling extract get "https://site.com" page.html -H "Accept: text/html" -H "Accept-Language: en-US"

Key options (browsers)

Both (fetch / stealthy-fetch) share options:

Option	Input type	Description
--headless / --no-headless	None	Run browser in headless mode (default: True)
--disable-resources / --enable-resources	None	Drop unnecessary resources for speed boost (default: False)
--network-idle / --no-network-idle	None	Wait for network idle (default: False)
--real-chrome / --no-real-chrome	None	If you have a Chrome browser installed on your device, enable this, and the Fetcher will launch an instance of your browser and use it. (default: False)
--timeout	INTEGER	Timeout in milliseconds (default: 30000)
--wait	INTEGER	Additional wait time in milliseconds after page load (default: 0)
-s, --css-selector	TEXT	CSS selector to extract specific content from the page. It returns all matches.
--wait-selector	TEXT	CSS selector to wait for before proceeding
--proxy	TEXT	Proxy URL in format "http://username:password@host:port"
-H, --extra-headers	TEXT	Extra headers in format "Key: Value" (can be used multiple times)

This option is specific to fetch only:

Option	Input type	Description
--locale	TEXT	Specify user locale. Defaults to the system default locale.

And these options are specific to stealthy-fetch only:

Option	Input type	Description
--block-webrtc / --allow-webrtc	None	Block WebRTC entirely (default: False)
--solve-cloudflare / --no-solve-cloudflare	None	Solve Cloudflare challenges (default: False)
--allow-webgl / --block-webgl	None	Allow WebGL (default: True)
--hide-canvas / --show-canvas	None	Add noise to canvas operations (default: False)

Examples:

# Wait for JavaScript to load content and finish network activity
scrapling extract fetch "https://scrapling.requestcatcher.com/" content.md --network-idle

# Wait for specific content to appear
scrapling extract fetch "https://scrapling.requestcatcher.com/" data.txt --wait-selector ".content-loaded"

# Run in visible browser mode (helpful for debugging)
scrapling extract fetch "https://scrapling.requestcatcher.com/" page.html --no-headless --disable-resources

# Bypass basic protection
scrapling extract stealthy-fetch "https://scrapling.requestcatcher.com" content.md

# Solve Cloudflare challenges
scrapling extract stealthy-fetch "https://nopecha.com/demo/cloudflare" data.txt --solve-cloudflare --css-selector "#padded_content a"

# Use a proxy for anonymity.
scrapling extract stealthy-fetch "https://site.com" content.md --proxy "http://proxy-server:8080"

Notes

• ALWAYS clean up temp files after reading
• Prefer .md output for readability; use .html only if you need to parse structure
• Use -s CSS 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)
