Compared to competing libraries, Crawlee is easier to use, yet also more feature rich. In just like 20 lines of code, you can have a crawler set up and ready to go that uses proxy rotation, automatic session management, header generation, fingerprint generation, and request management.
When building a crawler with Crawlee, you have more time to focus on the job at hand rather than reinventing the wheel and creating custom implementations for proxy-management or request-management etc.
