ScrapeGraphAI is an open-source web scraping library that uses LLMs to automatically extract structured data from websites. Instead of writing CSS selectors or XPath queries, developers describe what data they want in natural language. Supports multiple LLM providers and handles dynamic JavaScript-rendered pages.
Spider is a high-performance web crawler built in Rust that can crawl thousands of pages per second. It provides LLM-ready output formats, JavaScript rendering, and anti-bot bypassing, making it ideal for large-scale web data collection for AI applications.
