Crawlee is an advanced library for web scraping and browser automation, enabling the rapid creation of reliable crawlers. It allows seamless transitions between HTTP requests and headless browsers such as Puppeteer and Playwright, making it adaptable for any scraping need. Proxies are rotated intelligently to maintain their effectiveness, while browser headers are mimicked to give crawlers a more human-like appearance. Developed by experts who scrape millions of pages daily, Crawlee provides extensive configurability and automatic scaling, ensuring smooth execution of web scraping tasks.
