Web scraping has become an essential part of data analysis and extraction. It enables individuals and businesses to extract data from websites and online sources.
With web scraping, you can gather large amounts of data that can be used for research, lead generation, pricing analysis, market research, and much more.
However, web scraping can be challenging, especially when dealing with sites with measures to prevent scraping. This is where proxies come in handy.
This article will explore the best tools for web scraping with proxies and factors to consider when choosing your tools for web scraping.

What is web scraping?
Web scraping is the process of extracting data from websites and online sources. It involves writing code to access web pages and extract relevant data.
The extracted data can be stored in a database, spreadsheet, or any other data format for analysis. Web scraping is widely used in various industries, including eCommerce, market research, and search engine optimization.

What are proxies, and why are they used in web scraping?
Proxies are servers that act as intermediaries between your computer and the internet. When you connect to the internet using a proxy server, the server acts as a buffer between your computer and the websites you are accessing.
The proxy server receives your requests, forwards them to the websites, and then sends the website’s response back to your computer.
Proxies are used in web scraping to help prevent detection and IP blocking. Some websites have measures in place to prevent web scraping, and these measures can include IP blocking.
When you use a proxy server, the website sees the proxy server’s IP address instead of your computer’s. This makes detecting and blocking your scraping attempts harder for the website.

Puppeteer is a Node.js library that provides a high-level API to control headless Chrome or Chromium instances. It allows you to simulate user interactions with a website and extract data.
Puppeteer helps scrape dynamic web pages that require JavaScript rendering.
5. cURL
A cURL is a command-line tool that allows you to transfer data to and from web servers using protocols such as HTTP, FTP, SMTP, cURL socks5, etc.. cURL is not strictly a web scraping tool.
Still, it can be used for web scraping by sending HTTP requests to a website and retrieving the HTML content.
With cURL, you can specify the user-agent, cookies, and other parameters to simulate a web browser and make the request look like it’s coming from a real user.
