Crawl4AI is an open-source, asynchronous web scraping and crawling library built specifically for AI agents and LLM ingestion. Built on Python and Playwright, it executes JavaScript, captures screenshots, extracts structured data via CSS/XPath or LLM-driven schemas, and outputs clean Markdown. It supports concurrent multi-URL crawling, custom browser headers, and agent integration via Model Context Protocol (MCP). Users can run the library locally for free or connect to the managed Crawl4AI Cloud API.
