About Crawl4AI
Crawl4AI is a free, open-source Python library for crawling and scraping that is designed with language models in mind. It turns pages into clean markdown, handles JavaScript through a real browser and can run many crawls in parallel.
You can extract structured data with CSS selectors, rules or an LLM, and it supports sessions, proxies and custom hooks. Because it runs on your own machine or server, there are no per-page fees.
The project is completely free to use. It appeals to developers who want a fast, flexible crawler they control, especially for RAG and agent projects.

- Markdown output for LLMs
- Async parallel crawling
