Browser Automation Tools: Puppeteer vs Selenium WebDriver
Both Puppeteer and Selenium WebDriver are tools that help developers control web browsers through code. They're commonly used for automated testing, taking screenshots, and scraping web content. While Puppeteer works specifically with Chrome/Chromium browsers and is made by Google, Selenium WebDriver supports multiple browsers like Chrome, Firefox, and Safari.

Detailed Comparison
Technical Analysis
featureComparison
Puppeteer is a Node.js library developed by the Chrome team, providing a high-level API to control headless Chrome or Chromium. Selenium WebDriver is an open-source tool for automating web browsers, supporting multiple browsers and languages. Puppeteer is faster and more lightweight, while Selenium provides broader browser support.
typescriptSupport
Both packages have TypeScript definitions, ensuring type safety and auto-completion.
browserCompatibility
Puppeteer supports Chromium and Chrome, while Selenium supports Chrome, Firefox, Edge, Internet Explorer, and Safari.
dependencies
Puppeteer has 14 dependencies, including Chromium, while Selenium has 25 dependencies, including browser-specific ones.
performance
Puppeteer is generally faster due to its direct Chrome integration, while Selenium's performance varies depending on the browser.
Ecosystem Analysis
frameworkCompatibility
Both packages can be used with popular frameworks like React, Angular, and Vue.js.
communityActivity
Puppeteer has a more active community, with more GitHub stars and contributors.
documentationQuality
Both packages have high-quality documentation, with Puppeteer's being more extensive.
maintenanceStatus
Puppeteer is actively maintained by the Chrome team, while Selenium is maintained by the Selenium Project.
Performance Comparison
bundleSizeAnalysis
Puppeteer's bundle size is significantly smaller than Selenium's.
runtimePerformance
Puppeteer is generally faster due to its direct Chrome integration.
loadingTime
Puppeteer loads faster due to its smaller bundle size.
memoryUsage
Puppeteer uses less memory due to its more efficient architecture.
Code Examples
Puppeteer Example
1const puppeteer = require('puppeteer');
2(async () => {
3 const browser = await puppeteer.launch();
4 const page = await browser.newPage();
5 await page.goto('https://example.com');
6 await browser.close();
7})();This example launches a new Chrome instance, creates a new page, navigates to example.com, and closes the browser.
Selenium WebDriver Example
1const { Builder, By, Key, until } = require('selenium-webdriver');
2(async function example() {
3 let driver = await new Builder().forBrowser('chrome').build();
4 try {
5 await driver.get('https://example.com');
6 } finally {
7 await driver.quit();
8 }
9})();This example creates a new Chrome instance, navigates to example.com, and closes the browser using Selenium WebDriver.
Recommendation
Summary
Puppeteer is recommended for most use cases due to its faster performance, smaller bundle size, and more active community.
Details
- Puppeteer is ideal for automating Chromium-based browsers.
- Selenium is better suited for cross-browser testing and automation.

Installation
npm i puppeteer # Downloads compatible Chrome during installation. npm i puppeteer-core # Alternatively, install as a library, without downloading Chrome.
Example
import puppeteer from 'puppeteer'; // Or import puppeteer from 'puppeteer-core'; // Launch the browser and open a new blank page const browser = await puppeteer.launch(); const page = await browser.newPage(); // Navigate the page to a URL. await page.goto('https://developer.chrome.com/'); // Set screen size. await page.setViewport({width: 1080, height: 1024}); // Type into search box using accessible input name. await page.locator('aria/Search').fill('automate beyond recorder'); // Wait and click on first result. await page.locator('.devsite-result-item-link').click(); // Locate the full title with a unique string. const textSelector = await page .locator('text/Customize and automate') .waitHandle(); const fullTitle = await textSelector?.evaluate(el => el.textContent); // Print the full title. console.log('The title of this blog post is "%s".', fullTitle); await browser.close();
