Puppeteer and Playwright are the two dominant browser automation frameworks for web scraping. Both run headless browsers, both handle JavaScript rendering, and both integrate with proxies. But in 2026, the differences matter more than ever.
Quick Comparison
| Feature | Playwright | Puppeteer |
|---|---|---|
| Browsers | Chromium, Firefox, WebKit | Chromium only |
| Languages | JS, Python, Java, C# | JS, Python (unofficial) |
| Auto-wait | Built-in | Manual |
| Proxy support | Per-context | Per-browser |
| Stealth | Plugins available | Stealth plugin mature |
| Performance | Faster (browser reuse) | Good |
| Maintained by | Microsoft |
Playwright: The Modern Choice
Playwright was built to fix Puppeteer's pain points. Its killer feature for scraping: per-context proxy rotation.
const { chromium } = require('playwright');
// Two sticky lines generated in the ZentisLabs dashboard or API// ("host:port:user:pass"), used exactly as generated: each is pinned// to one gateway node, so each context keeps its own IP.const lines = ['PASTE_STICKY_LINE_1', 'PASTE_STICKY_LINE_2'];const toProxy = (line) => { const [host, port, username, password] = line.split(':'); return { server: `http://${host}:${port}`, username, password };};
(async () => { const browser = await chromium.launch();
// Each context uses a different proxy and is fully isolated const context1 = await browser.newContext({ proxy: toProxy(lines[0]) });
const context2 = await browser.newContext({ proxy: toProxy(lines[1]) });
// Both run in parallel with different IPs const page1 = await context1.newPage(); const page2 = await context2.newPage();
await Promise.all([ page1.goto('https://site.com/page/1'), page2.goto('https://site.com/page/2'), ]);})();Auto-Waiting
Playwright automatically waits for elements to be visible, stable, and actionable:
// Playwright - just works, waits automaticallyawait page.click('.load-more');const text = await page.textContent('.result');
// Puppeteer - you often need manual waitsawait page.waitForSelector('.result', { visible: true });await page.click('.load-more');await page.waitForTimeout(2000);const text = await page.$eval('.result', el => el.textContent);Puppeteer: Still Relevant
Puppeteer's stealth ecosystem is more battle-tested:
const puppeteer = require('puppeteer-extra');const StealthPlugin = require('puppeteer-extra-plugin-stealth');puppeteer.use(StealthPlugin());
(async () => { const browser = await puppeteer.launch({ args: ['--proxy-server=http://basic.resi.zentislabs.com:12321'], headless: 'new', });
const page = await browser.newPage(); await page.authenticate({ username: 'USER', password: 'PASS' });})();Proxy Integration: Head to Head
Playwright (Python)
from playwright.sync_api import sync_playwright
with sync_playwright() as p: browser = p.chromium.launch() context = browser.new_context( proxy={ "server": "http://basic.resi.zentislabs.com:12321", "username": "USER", "password": "PASS_country-us" } ) page = context.new_page() page.goto("https://target-site.com") content = page.content() browser.close()Puppeteer (Python)
import asynciofrom pyppeteer import launch
async def main(): browser = await launch( args=['--proxy-server=http://basic.resi.zentislabs.com:12321'] ) page = await browser.newPage() await page.authenticate({'username': 'USER', 'password': 'PASS'}) await page.goto('https://target-site.com') content = await page.content() await browser.close()
asyncio.run(main())Winner: Playwright. Per-context proxy assignment means you can run 10 parallel scrapes with 10 different IPs in a single browser instance. Puppeteer requires launching separate browser processes for different proxies.
Performance Compared
What to expect when you run both on a ZentisLabs Advanced server (8 vCPU, 16 GB RAM):
| Metric | Playwright | Puppeteer |
|---|---|---|
| Sequential runs | Slightly faster | Baseline |
| Parallel scraping | Faster: one browser, many contexts | Slower: one browser per proxy |
| Memory per page | Lower | Higher |
| Failed pages | Fewer, thanks to auto-wait | More without manual waits |
Which Should You Choose?
Choose Playwright when: you need parallel scraping with different proxies, you're using Python/Java/C#, you want auto-waiting, you need multi-browser testing, or you're starting fresh.
Choose Puppeteer when: you need the stealth plugin ecosystem (more battle-tested), you're maintaining existing Puppeteer code, or you need raw Chrome DevTools Protocol access.
For new web scraping projects in 2026, Playwright is the better choice. Pair it with ZentisLabs residential proxies - give each browser context its own generated sticky line and every context browses from its own residential IP.
