Let us focus on some of the similarities between Puppeteer and Selenium. The two are open-source automation solutions that help to handle mundane and repetitive tasks efficiently. You write some conditional statements and specify the actions you want the code to take when those conditions are fulfilled. Apart from data gathering, they are also used for quality assurance and end-to-end testing of software.
The rest of this article discusses the meaning and main features of proxies. In the same breath, we will highlight the major differences between Puppeteer and Selenium. The article will end with powerful use cases that combine both with proxies.
Proxies are intermediaries between your computer and the target server. When you place a web page request, the proxy server intercepts the request, which then masks your IP address before forwarding that request to the target. The proxy will also receive the response from the server on your behalf before forwarding this to you.
Automation with Selenium or Puppeteer without proxies is like shopping at Walmart without picking up a cart. Although you might be able to pick up a few items, when you need more items and run out of hands, you will need to reach out for a cart. Using a selenium and puppeteer proxy gives you a better fighting chance against geo-blocking, IP ban, and the menace of CAPTCHAs.
Although they share some similarities, some of the differences include the following:
Two sides to the same coin, although one is more complex and robust. Selenium and Puppeteer were developed to test applications and perform quality assurance by manipulating browsers. This has found a home in data gathering, simplifying the process into API calls and reducing the writing of low-level codes. Adding a layer of proxies onto these two will allow your company to get more data scraping done without bothering about IP blocks, CAPTCHAs, and geo-location bans.
If your developers are more familiar with JavaScript, it would be helpful to make use of Puppeteer as it has a lesser learning curve.
