Firecrawl: Turn Any Website Into Agent-Ready Markdown
Firecrawl converts messy, JavaScript-rendered websites into clean, LLM-ready markdown for RAG and AI agents. Install with 'pip install firecrawl' and use the Firecrawl class: scrape for known URLs (1 credit), crawl for discovery (1 credit per page, always set a limit), and schema-based extraction for typed JSON. Watch Enhanced/Stealth Mode, which costs 5 credits per page on Cloudflare-protected sites, and note that credits do not roll over.
