Scale Web Scraping Using a Real Browser with Built-in Proxies and Web Unblockers

Introduction

Image description

Web scraping is an essential tool for developers, data analysts, and researchers to extract information from public web data. However, web scraping can be a challenging and time-consuming task due to various hurdles such as captchas, user agent blocking, and IP blocking.

I recently asked on Twitter:

After reading your answers, opinions, and suggestions I came to write this article!

In this article, we'll discuss the key issues faced by developers during web scraping, the solutions to these problems, and how Bright Data's Scraping Browser is the superior solution.

Issues Faced by Developers When Scraping Public Web Data 👀

  1. Captchas: Websites often use captchas to prevent automated access and protect their content from web scrapers. These captchas can be difficult and time-consuming to bypass.

  2. User agent blocking: Some websites restrict access based on the user agent string. Scrapers need to mimic different user agents to blend in with regular browser traffic.

  3. IP blocking: Websites might block IP addresses if they suspect automated web scraping. Changing IP addresses frequently and using proxies can help overcome this issue, but it requires additional setup and management.

  4. Proxy network setup: Establishing a reliable proxy network can be complex, requiring setup, rotation, load balancing, and error handling.

  5. Resource: Web scraping can be resource-intensive, involving substantial developer time and infrastructure expenses for large-scale projects.

Use Case: Monitoring Stock Availability on Retail Websites

In this scenario, a developer is tasked with monitoring stock availability for specific products across various retail websites. These websites frequently use JavaScript rendering and AJAX to display stock information, posing a challenge for traditional web scraping methods.

The Scraping Browser API proves beneficial as it efficiently handles JavaScript rendering and AJAX content. By automating browser interactions, it navigates through retail websites, loads dynamic content, and extracts stock availability information for the target products.

Leveraging the data extracted by the Scraping Browser API, developers can support informed decision-making about product inventory, pricing, and marketing strategies. Additionally, the API's compatibility with Puppeteer and Playwright makes it an ideal solution for developers already acquainted with those browser automation libraries.
