Comprehensive Comparison of Puppeteer and Selenium Automation Frameworks
Factor	Puppeteer	Selenium
Browser Support	Primarily supports Chrome and Chromium. Partial support for Firefox, but APIs are limited.	Supports a wide range of browsers, including Chrome, Firefox, Safari, Edge, and Internet Explorer.
Programming Languages	JavaScript and Node.js	Supports Python, Java, C#, Ruby, JavaScript, and Kotlin
Ease of Setup	Quick and straightforward setup. Comes with Chromium pre-installed.	Multi-step setup requiring a WebDriver for each browser and environment configuration. More complex but flexible.
Primary Use Cases	Ideal for web scraping, browser automation, PDF generation, and testing JavaScript-heavy applications.	Best for cross-browser testing, end-to-end testing, and large-scale automation projects.
Cross-Browser Testing	Limited to Chromium-based browsers, with minimal Firefox support.	Cross-browser compatibility for testing and scraping across various environments.
Headless Mode	Optimized for headless execution with Chromium.	Supports headless mode across multiple browsers.
Parallel Testing	Limited to Chromium environments, suitable for small to mid-scale testing.	Selenium Grid allows parallel testing across multiple machines and browsers.
Dynamic Content	Excellent at handling JavaScript-heavy websites and rendering complex DOM structures.	Can manage dynamic content but is less efficient than Puppeteer
Advanced Features	Offers screenshot capture, PDF generation, and network interception.	Provides a reliable suite featuring WebDriver, IDE, and Grid.
Ideal Users	Developers proficient in JavaScript and Node.js, working on Chrome-specific projects or scraping.	Teams need cross-browser support and language flexibility for large-scale or diverse automation projects.
