What is the Difference Between n8n Puppeteer and Playwright Nodes?

When building web automation workflows in n8n, you'll encounter two powerful browser automation nodes: Puppeteer and Playwright. While both enable headless browser operations for web scraping and testing, they have distinct characteristics that make each suitable for different scenarios. This guide explores the key differences to help you choose the right tool for your n8n workflows.

Overview of n8n Browser Automation Nodes

Both Puppeteer and Playwright nodes in n8n allow you to: - Navigate to web pages and interact with elements - Execute JavaScript in the browser context - Take screenshots and generate PDFs - Handle dynamic content and AJAX requests - Automate form submissions and user interactions

However, their underlying technologies and capabilities differ significantly.

Core Architectural Differences

Puppeteer Node

Puppeteer is a Node.js library developed by Google's Chrome team that provides a high-level API to control Chrome or Chromium browsers. In n8n, the Puppeteer node wraps this library for workflow automation.

Key characteristics: - Browser Support: Primarily supports Chrome/Chromium (though Firefox support exists experimentally) - API Design: Chrome DevTools Protocol-based - Maintenance: Maintained by Google Chrome team - Maturity: Older, more established in the ecosystem - Performance: Optimized specifically for Chromium-based browsers

Playwright Node

Playwright is a newer browser automation framework developed by Microsoft, created by former Puppeteer team members. The n8n Playwright node leverages this cross-browser testing framework.

Key characteristics: - Browser Support: Native support for Chrome, Firefox, Safari (WebKit), and Edge - API Design: Modern, unified API across all browsers - Maintenance: Maintained by Microsoft - Maturity: Newer but rapidly evolving - Performance: Optimized for parallel execution and multi-browser testing

Feature Comparison

Browser Support

Puppeteer:

// n8n Puppeteer node - Chromium only by default
{
  "browser": "chromium",
  "headless": true
}

Playwright:

// n8n Playwright node - Multiple browser options
{
  "browser": "chromium", // or "firefox", "webkit"
  "headless": true
}

If you need to test across different browsers or require Safari/WebKit compatibility, Playwright is the clear choice. For Chrome-only automation, both work equally well.

Page Navigation and Waiting

Both nodes provide similar navigation capabilities, but Playwright offers more granular control over network and load states.

Puppeteer navigation:

// Puppeteer-style navigation in n8n
await page.goto('https://example.com', {
  waitUntil: 'networkidle2' // or 'load', 'domcontentloaded', 'networkidle0'
});

Playwright navigation:

// Playwright-style navigation in n8n
await page.goto('https://example.com', {
  waitUntil: 'networkidle' // or 'load', 'domcontentloaded', 'commit'
});

// Playwright also supports waiting for specific states
await page.waitForLoadState('networkidle');

Playwright's approach to handling timeouts is more flexible with built-in retry mechanisms.

Element Interaction

Puppeteer selector handling:

// In n8n Puppeteer node
const element = await page.$('#button');
await element.click();

// Or using page methods
await page.click('#button');
await page.type('#input', 'text');

Playwright selector handling:

// In n8n Playwright node
await page.click('#button');
await page.fill('#input', 'text');

// Playwright's auto-wait mechanism
await page.click('button:has-text("Submit")'); // Waits automatically

Playwright includes automatic waiting for elements to be actionable (visible, enabled, stable), reducing the need for explicit wait commands. This makes workflows more reliable when interacting with DOM elements.

Authentication and State Management

Puppeteer authentication:

// HTTP Basic Authentication
await page.authenticate({
  username: 'user',
  password: 'pass'
});

// Cookie-based sessions
await page.setCookie({
  name: 'session',
  value: 'token123',
  domain: 'example.com'
});

Playwright authentication:

// HTTP credentials
await page.context().setHTTPCredentials({
  username: 'user',
  password: 'pass'
});

// Persistent context with saved state
const context = await browser.newContext({
  storageState: 'auth.json' // Reuse authentication
});

Playwright's context-based approach makes handling authentication and session management more robust, especially for workflows that need to maintain state across multiple pages.

Network Interception

Puppeteer network control:

// Intercept requests
await page.setRequestInterception(true);
page.on('request', request => {
  if (request.resourceType() === 'image') {
    request.abort();
  } else {
    request.continue();
  }
});

Playwright network control:

// Route-based interception
await page.route('**/*.{png,jpg,jpeg}', route => route.abort());

// Mock API responses
await page.route('**/api/data', route => {
  route.fulfill({
    status: 200,
    body: JSON.stringify({ data: 'mocked' })
  });
});

Playwright's routing API is more intuitive and powerful for monitoring network requests and mocking responses.

Performance Considerations

Execution Speed

Puppeteer: - Faster for single-browser Chrome automation - Lower memory overhead for simple tasks - Well-optimized for Chromium-specific features

Playwright: - Better for parallel execution across multiple contexts - More efficient when running multiple browser instances - Built-in support for browser context isolation

Resource Usage

In n8n workflows, resource considerations matter:

| Aspect | Puppeteer | Playwright | |--------|-----------|------------| | Memory footprint | Lower for single browser | Higher due to multi-browser support | | CPU usage | Moderate | Slightly higher | | Startup time | Faster | Slightly slower | | Parallel execution | Manual implementation | Built-in support |

For high-volume scraping with multiple pages in parallel, Playwright's architecture provides advantages.

Use Case Recommendations

Choose Puppeteer When:

Chrome-only automation: Your workflow only needs to target Chrome/Chromium
Lightweight tasks: Simple navigation and data extraction
Existing Puppeteer knowledge: Your team has Puppeteer expertise
Resource constraints: Running on limited memory environments
Legacy workflows: Migrating existing Puppeteer scripts to n8n

Example n8n Puppeteer workflow:

// Simple product price scraper
{
  "nodes": [
    {
      "type": "n8n-nodes-base.puppeteer",
      "parameters": {
        "url": "https://example.com/product",
        "operation": "getPageContent",
        "selector": ".price"
      }
    }
  ]
}

Choose Playwright When:

Cross-browser testing: Need to verify functionality across browsers
Complex interactions: Advanced automation with multiple contexts
Modern web apps: Working with SPAs and dynamic content

Better reliability: Auto-waiting and retry mechanisms are critical

Example n8n Playwright workflow:

// Cross-browser form testing
{
  "nodes": [
    {
      "type": "n8n-nodes-base.playwright",
      "parameters": {
        "browser": "firefox",
        "url": "https://example.com/form",
        "operation": "executeAction",
        "actions": [
          { "type": "fill", "selector": "#email", "value": "test@example.com" },
          { "type": "click", "selector": "button[type='submit']" },
          { "type": "waitForSelector", "selector": ".success-message" }
        ]
      }
    }
  ]
}

Migration Considerations

If you're considering migrating from Puppeteer to Playwright in your n8n workflows:

API Similarities

Most basic operations have direct equivalents:

// Puppeteer → Playwright
page.goto(url) → page.goto(url)
page.click(selector) → page.click(selector)
page.$(selector) → page.locator(selector)
page.evaluate(fn) → page.evaluate(fn)

Key Differences to Handle

Context management: Playwright uses browser contexts more explicitly
Waiting strategies: Playwright's auto-wait reduces explicit waits
Selector syntax: Playwright supports additional selector engines
Error handling: Different timeout and error behaviors

Integration with WebScraping.AI

For production web scraping workflows in n8n, both Puppeteer and Playwright nodes can be complemented with WebScraping.AI's API to handle:

Anti-bot protection: Bypass advanced bot detection systems
Proxy rotation: Automatic IP rotation for large-scale scraping
JavaScript rendering: Cloud-based rendering without local browser overhead
Rate limiting: Managed request throttling and scheduling

Example n8n workflow combining Playwright with WebScraping.AI:

{
  "nodes": [
    {
      "type": "n8n-nodes-base.httpRequest",
      "name": "WebScraping.AI",
      "parameters": {
        "url": "https://api.webscraping.ai/html",
        "qs": {
          "api_key": "={{$credentials.webScrapingAI.apiKey}}",
          "url": "https://example.com",
          "js": true
        }
      }
    },
    {
      "type": "n8n-nodes-base.playwright",
      "name": "Additional Processing",
      "parameters": {
        "operation": "executeCustomCode",
        "code": "// Process extracted data"
      }
    }
  ]
}

Conclusion

Both Puppeteer and Playwright nodes in n8n are powerful tools for browser automation, each with distinct advantages:

Use Puppeteer for straightforward Chrome automation with minimal overhead
