Frequently Asked Questions
Should I choose Crawl4AI or Firecrawl for LLM web scraping in 2026?
Choose Crawl4AI (`unclecode/crawl4ai`, 38.5k stars, 100% free Apache-2.0) when you want a self-hosted Python async Playwright crawler with BM25 Fit-Markdown pruning that strips 96% of boilerplate DOM tokens in 290ms p50 without paying per-page cloud API fees. Choose Firecrawl (`mendableai/firecrawl`, 26.2k stars) when you need turnkey managed anti-bot stealth, proxy rotation, subpage domain mapping (`/map`), and structured schema extraction (`/extract`) out of the box.
How do Crawl4AI and Spider cut Bright Data and Apify bills by 95%?
Commercial scraping proxies and web crawling clouds like Bright Data and Apify charge $500-$2,500+/month for residential proxy bandwidth and actor runtime compute. Running Crawl4AI or Rust-based Spider (`spider-rs/spider`, 6.4k stars, 10,000+ pages/sec in 35MB RAM) on standard container compute crawls 500,000+ pages/month for ~$85/month (-94.8%).
