Playwright

• ›Claude Desktop or Cursor with MCP support
• ›Understanding of web scraping ethics and robots.txt
• ›Rate limiting awareness to avoid overwhelming target sites
• ›Knowledge of legal restrictions on data collection

20-40 minutes including configuration and testing

• +Check robots.txt and respect crawl rules
• +Rate limit requests: 1-2 requests/second maximum
• +Use official APIs when available instead of scraping
• +Identify your bot with descriptive user agent
• +Cache results to minimize repeated requests
• +Handle errors gracefully with retries and fallbacks
• +Validate extracted data for accuracy

• −Don't scrape sites that explicitly forbid it (robots.txt, ToS)
• −Don't overwhelm servers with rapid requests—use rate limiting
• −Don't scrape personal data without consent and legal basis
• −Don't ignore copyright on extracted content
• −Don't assume HTML structure is stable—handle changes
• −Don't use scraped data for commercial purposes without permission

Use for research automation, content monitoring, data aggregation from multiple sources, and when official APIs don't exist. Best for read-only information gathering.

Avoid for sites with APIs (use API instead), sites that explicitly forbid scraping, when data is copyrighted, or for login-required content without proper authorization.
