Using Proxies with Cloudscraper: A Simple Guide
In this article, I’ll share how I use proxies with Cloudscraper to ensure I can scrape the data I need, even from sites with heavy protection.
What is Cloudscraper?
Cloudscraper is a Python library designed to bypass Cloudflare’s anti-bot protection. Cloudflare is known for using technologies like CAPTCHA challenges and JavaScript puzzles to prevent automated website access. Without the right tools, your scraping requests may hit a wall, be flagged as bots, and subsequently blocked.
Cloudscraper automatically handles the challenges and interactions required to access a website protected by Cloudflare. It simplifies web scraping efforts by emulating browser-like behavior, making your requests appear more legitimate.
Why Use Proxies with Cloudscraper?
Proxies play a critical role in ensuring anonymity and avoiding IP bans. Websites often impose rate limits, detecting a single IP address and making too many requests over a short period. They can throttle or block your IP address if detected, preventing your bot from accessing their content. Using proxies allows you to:
- Avoid IP blocking by rotating IP addresses.
- Improve anonymity and evade detection.
- Access geo-blocked content by using proxies from different locations.
When combined with Cloudscraper, proxies further enhance your web scraping strategy by making it nearly impossible for websites to track your IP address or recognize your scraper as a bot.
Setting Up Cloudscraper
Before diving into how to integrate proxies with Cloudscraper, you need to install Cloudscraper on your system. Here’s how you can get started:
Install Cloudscraper: Open your terminal and run the following command:
pip install cloudscraper
Basic Usage of Cloudscraper: After installation, using Cloudscraper is simple. Here’s an example code snippet:
import cloudscraper
# Create a Cloudscraper instance
scraper = cloudscraper.create_scraper()
# Make a request to a Cloudflare-protected website
url = "https://example.com"
response = scraper.get(url)
print(response.content)
This basic setup allows you to bypass Cloudflare’s security, but adding proxies can significantly improve effectiveness.
Choosing the Right Proxy Type
Proxies come in various types, each suitable for different scraping scenarios. Here’s a quick overview:
- Residential Proxies: IP addresses assigned to home users by Internet Service Providers (ISPs). Residential proxies offer a higher level of anonymity since they appear to be genuine users. However, they are more expensive than other types of proxies.
- Datacenter Proxies: These proxies are generated from data centers and offer faster speeds at a lower cost. However, websites can easily detect and block them because multiple users may be assigned the same IP address.
- Rotating Proxies: These proxies automatically switch IP addresses regularly, making it harder for websites to detect scraping activities.
- Geo-Location Proxies: These proxies allow you to access websites as if browsing from a specific country. This is useful when dealing with geo-blocked content.
The choice of proxy can significantly affect your scraping success when using Cloudscraper. Residential and rotating proxies generally work best when dealing with Cloudflare-protected websites.
Setting Up Proxies with Cloudscraper
Let’s look at how to configure Cloudscraper to work with proxies. Cloudscraper uses the requests library under the hood, so proxy configuration is straightforward.
Setting Up a Single Proxy
If you’re using a single proxy, Cloudscraper allows you to route all requests through that proxy easily. Here’s how to set it up:
import cloudscraper
# Create a Cloudscraper instance
scraper = cloudscraper.create_scraper()
# Set up a proxy
proxy = {
"http": "http://your_proxy_address:port",
"https": "https://your_proxy_address:port"
}
# Make a request using the proxy
url = "https://example.com"
response = scraper.get(url, proxies=proxy)
print(response.content)
Using Rotating Proxies
For larger scraping tasks, using a single proxy won’t suffice. A rotating proxy can help distribute the load across multiple IP addresses, preventing you from getting blocked.
To use a rotating proxy service, you typically receive a proxy pool with many IP addresses. These proxies automatically rotate, meaning each request may come from a different IP.
Here’s an example of how to integrate rotating proxies with Cloudscraper:
import cloudscraper
from itertools import cycle
# List of proxies
proxies = [
"http://proxy1_address:port",
"http://proxy2_address:port",
"http://proxy3_address:port",
# Add as many proxies as needed
]
# Create a rotating proxy cycle
proxy_pool = cycle(proxies)
# Create a Cloudscraper instance
scraper = cloudscraper.create_scraper()
# Function to get a URL using rotating proxies
def get_url_with_proxy(url):
proxy = next(proxy_pool)
response = scraper.get(url, proxies={"http": proxy, "https": proxy})
return response.content
# Scraping example
url = "https://example.com"
for i in range(10): # Scraping the same URL multiple times
print(get_url_with_proxy(url))
Using a rotating proxy, you distribute your requests across multiple IP addresses, reducing the chances of detection and blocking.

Geo-Location Proxies
You may need to use proxies from a specific country to scrap geo-blocked content. Many proxy providers offer location-based proxies, allowing you to select proxies based on the country or region.
Here’s how you can set up a country-specific proxy:
import cloudscraper
# Create a Cloudscraper instance
scraper = cloudscraper.create_scraper()
# Set up a proxy from a specific location
proxy = {
"http": "http://us_proxy_address:port",
"https": "https://us_proxy_address:port"
}
# Make a request using the geo-location proxy
url = "https://example.com"
response = scraper.get(url, proxies=proxy)
print(response.content)
In this example, you would use a proxy from the United States. This method can be useful for scraping content restricted to specific regions.
Best Practices for Using Proxies with Cloudscraper
Following best practices when using proxies with Cloudscraper is essential to make the most out of your scraping tasks. Below are a few tips to keep in mind:
- Use Residential or Rotating Proxies: If you’re scraping heavily protected websites, consider using residential or rotating proxies for better performance and fewer blocks.
- Respect Website’s Terms of Service: Ensure that your scraping activities do not violate the target website’s terms of service.
- Throttle Your Requests: Even when using proxies, sending too many requests quickly can raise red flags. Add delays between requests to mimic human browsing behavior.
- Use Proxy Pools: Don’t rely on a single proxy for large scraping tasks. Use a proxy pool to rotate between different IP addresses.
- Check for CAPTCHAs: Some websites may throw CAPTCHAs despite using proxies and Cloudscraper. Integrating a CAPTCHA-solving service may help you bypass these challenges.
- Monitor Proxy Health: Regularly check the health of your proxies. Over time, some proxies may slow down or become inactive, which could affect your scraping speed and efficiency.
Conclusion
Using proxies with Cloudscraper is an effective way to bypass anti-bot mechanisms, protect your identity, and ensure successful web scraping operations. By choosing the right proxy type and properly configuring it with Cloudscraper, you can scrape websites without getting blocked or detected.
Remember, while Cloudscraper and proxies help automate web scraping, it’s important to follow legal guidelines and respect the target website’s terms of service. With the right approach and tools, you can gather valuable data while remaining undetected by even the most sophisticated anti-scraping systems.
