Web scraping will never be the same!

Crawl4AI simplifies web crawling and data extraction, making it ready to use for LLMs and AI applications.

Here’s why it’s a game-changer:

🆓 Free and open-source
🚀 Blazing fast performance,
🤖 LLM-friendly output formats (JSON, cleaned HTML, markdown)
🌍 Supports crawling multiple URLs simultaneously
🎨 Extracts all media tags (Images, Audio, Video)
🔗 Extracts all external and internal links

But that’s not all:

📚 Extracts metadata from pages
🕵️ User-agent customization
🖼️ Takes screenshots of pages
📜 Executes custom JavaScript before crawling
