Web scraping (parte 2)

Playwright vs Puppeteer vs Selenium

 Playwright is the recommended default for new web automation and scraping projects in 2026 due to its built-in auto-waiting, multi-browser support (Chromium, Firefox, WebKit), and superior performance. 

 It offers the best balance of speed, reliability, and developer experience, including features like a built-in trace viewer and code generator.

Puppeteer is optimal for Chrome/Chromium-only tasks where lightweight execution and direct Chrome DevTools Protocol (CDP) access are prioritized.  It is ideal for Node.js developers needing a simple API for screenshots, PDFs, or basic scraping, but lacks native multi-browser capabilities. 

Selenium remains the standard for legacy systems, Java/C# environments, and projects requiring broadest browser compatibility (including older browsers like Internet Explorer).  While it has a larger ecosystem and supports more programming languages, it generally suffers from slower execution speeds and requires manual wait handling compared to modern alternatives.
