Scrapy

Scrapy is a fast Python framework with asynchronous requests, parallel crawling, and built-in data handling. It is maintained by Zyte (formerly Scrapinghub) and many other contributors. Scrapy combines the functionalities of an HTTP client and a parser with many built-in and third-party middleware for managing proxies, data cleaning, storage, and more. In Scrapy, spiders are Python classes that define how to follow links and extract data from websites. Scrapy uses CSS selectors to extract data from HTML pages efficiently. An asynchronous engine crawls many pages at once, with retries, throttling, and caching handled automatically. Scrapy is the most popular web scraping framework and remains the industry standard for large-scale data extraction. It requires Python 3.10+ and is cross-platform.
