## **Why choose Crawl4AI**

- LLM extraction via any LiteLLM provider, plus CSS/XPath/regex
- Clean and 'fit' markdown output
- Playwright browser control, stealth, sessions, proxies
- Deep crawling strategies (BFS/DFS/best-first)

### **Watch out for**

- You run and maintain the browsers and proxies yourself
- No built-in residential proxy network or managed unblocking
- LLM extraction costs depend on your own model provider

## **Why choose Diffbot**

- Automatic Extract APIs (article, product, discussion etc.) with no rules
- Crawlbot for whole-site crawling
- Knowledge Graph of organizations, people and articles
- Natural-language processing API

### **Watch out for**

- High jump from free to $299/mo
- Fixed page-type schemas; less flexible than prompt-based extraction
- Knowledge Graph credits are expensive per record
