What is Crawl4AI?

Open-source LLM-friendly web crawler and scraper with clean Markdown output, multiple extraction strategies, MCP server integration, and crash recovery for production RAG pipelines.

Crawl4AI is the most-starred open-source web crawler on GitHub (50k+ stars), built specifically for turning web content into clean, LLM-ready data for RAG pipelines, AI agents, and data workflows. Where general-purpose scrapers focus on raw HTML extraction, Crawl4AI optimizes its output for AI consumption — producing clean Markdown, structured JSON, and pre-chunked text ready for embedding.

The library provides multiple extraction strategies. The LLM-based strategy uses language models to extract structured data from pages using natural language instructions — describe what data you want in plain English instead of writing CSS selectors. The CSS/XPath strategy handles traditional rule-based extraction for known page structures. JSON schema-based extraction produces typed output matching your defined schemas. For content-heavy pages, the 'Fit Markdown' mode applies heuristic filtering and BM25 content scoring to strip boilerplate and surface the most relevant content.
