What is Crawl4AI?
Crawl4AI is an open-source Python library (Apache 2.0) for crawling and scraping web pages into clean, structured Markdown, built for LLM and AI-agent data pipelines. It supports CSS/XPath-based and LLM-based structured data extraction. Playwright-based browser automation is built in, with session, proxy, cookie, and stealth support plus parallel and adaptive crawling. It installs via pip or runs through Docker with an API gateway; a hosted Crawl4AI Cloud API is in closed beta, with no published pricing.
Our verdict
The core library is free, self-hosted, and backed by a large community (74.9K+ GitHub stars). That fits teams building LLM data pipelines who don't mind running their own Python and Playwright infrastructure. A managed, no-ops option isn't available: the hosted Cloud API is still in closed beta, with no published pricing.

Crawling frameworks give engineering teams full control over their pipeline: where it runs, how it scales, and what it collects. The trade is that anti-bot work and infrastructure become your problem rather than a vendor's, which is why they pair well with a proxy network.
