Scrapy

Beautiful Soup is a Python library for pulling data out of HTML and XML files. While Scrapy can use Beautiful Soup for parsing, Scrapy has its own built-in CSS and XPath selectors, making them alternatives for web scraping.

Selenium is a browser automation tool. It can be used for web scraping, especially when dealing with JavaScript-heavy websites, providing dynamic content rendering that Scrapy might struggle with directly. Selenium is often used in place of Scrapy or alongside it for handling complex scraping scenarios.

Puppeteer is a Node library which provides a high-level API to control Chrome or Chromium programmatically. It's often used to scrape dynamic single-page applications or render Javascript heavy content which Scrapy is not designed for.

Playwright is a framework for automating web browsers. It can be used for web scraping, especially when dealing with JavaScript-heavy websites, providing dynamic content rendering that Scrapy might struggle with directly. Playwright is often used in place of Scrapy or alongside it for handling complex scraping scenarios.

Requests is a Python library for making HTTP requests. While Scrapy has its own request/response handling, `requests` can be used for tasks outside the core scraping process, such as interacting with APIs or handling complex authentication schemes.

Pandas is a Python library for data analysis and manipulation. Scrapy is often used to extract data, which is then loaded into Pandas DataFrames for cleaning, transforming, and analyzing.

XPath is a query language for selecting nodes from an XML document. Scrapy uses XPath expressions to select specific elements from HTML pages during scraping.
