Puppeteer Core vs Selenium

Developers should use Puppeteer Core when they need to automate browser tasks in environments where they already have Chrome/Chromium installed, such as in CI/CD pipelines or server-side applications, to reduce dependencies and improve performance meets developers should learn selenium when they need to automate functional, regression, or cross-browser testing for web applications, as it helps ensure software quality and reduces manual testing efforts. Here's our take.

Puppeteer Core

Nice Pick

Developers should use Puppeteer Core when they need to automate browser tasks in environments where they already have Chrome/Chromium installed, such as in CI/CD pipelines or server-side applications, to reduce dependencies and improve performance

Pros

• It is ideal for web scraping, automated testing, and generating PDFs from web pages, as it offers precise control over browser behavior and supports modern web standards
• Related to: node-js, javascript

Cons

• Specific tradeoffs depend on your use case

Selenium

Developers should learn Selenium when they need to automate functional, regression, or cross-browser testing for web applications, as it helps ensure software quality and reduces manual testing efforts

Pros

• It is particularly useful in agile and DevOps environments for continuous integration and delivery pipelines, where automated tests can be integrated with tools like Jenkins or GitHub Actions
• Related to: webdriverio, testng

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Puppeteer Core is a library while Selenium is a tool. We picked Puppeteer Core based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Puppeteer Core wins

Based on overall popularity. Puppeteer Core is more widely used, but Selenium excels in its own space.
