Crawlee
Overview :
Crawlee is a Python library for building reliable web crawlers to extract data for use in AI, LLMs, RAG, or GPTs. It provides a unified interface for handling both HTTP and headless browser crawling tasks, supports automatic parallelization based on system resources, and comes with a clean and elegant API built on standard asynchronous IO. Unlike Scrapy, Crawlee offers native support for headless browser crawling. It is written in Python and includes type hints, enhancing the development experience and minimizing errors. Crawlee boasts features like automatic retries, integrated proxy rotation and session management, configurable request routing, a persistent URL queue, and pluggable storage options.
Target Users :
Crawlee is perfect for developers who need to build data scraping and web automation tools. Whether you need to extract data from static HTML pages or dynamic websites that rely on client-side JavaScript to generate content, Crawlee offers powerful support. Its ease of use and flexibility make it an ideal choice for data scientists, machine learning engineers, and web developers.
