How to Avoid Detection in Playwright Scraping (2026)

Why Playwright Gets Detected

Playwright drives a real Chromium (or Firefox/WebKit) browser, so it’s already closer to a real user than a simple HTTP client. Sites can still detect automation via browser flags (e.g. navigator.webdriver), fingerprint (canvas, WebGL, fonts), behavior (timing, lack of mouse movement), and IP (datacenter vs residential). This guide covers how to reduce detection when using Playwright for scraping. See browser fingerprinting, how websites detect scrapers, and web scraping without getting blocked. For production, combine with residential proxies and best proxies for web scraping.

Browser launch and context (reduce obvious bot flags)

Use a realistic viewport, locale, and timezone so the environment matches a normal user. Avoid headless if the site is very strict (use headless: false or the newer “headed/headless=auto” modes).

Example Playwright launch with basic stealth defaults:

import { chromium } from 'playwright';

const browser = await chromium.launch({
  headless: true, // try false if a site is very strict
});

const context = await browser.newContext({
  viewport: { width: 1366, height: 768 },
  userAgent:
    'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/122.0.0.0 Safari/537.36',
  locale: 'en-US',
  timezoneId: 'America/New_York',
});

const page = await context.newPage();

Proxies and IP (don’t look like a bot farm)

The IP is one of the strongest signals. Datacenter IPs are often blocked or limited. Use rotating residential proxies so traffic comes from real-user IPs.

Playwright proxy example:

import { chromium } from 'playwright';

const browser = await chromium.launch({
  headless: true,
  proxy: {
    server: 'http://p1.bytesflows.com:8001',
    username: process.env.BYTESFLOWS_USERNAME,
    password: process.env.BYTESFLOWS_PASSWORD,
  },
});

Pair this with proxy rotation strategies so each session or request isn’t always from the same IP. See using proxies with Playwright, why residential proxies, avoid IP bans, and Proxy Checker. Best proxies for web scraping and Proxies.

Fingerprint and headers (look like a real browser)

Playwright sends browser-like headers by default. To further reduce fingerprinting:

• Keep a consistent viewport and user agent per session.
• Avoid switching devices (mobile/desktop) too frequently on the same account.
• Don’t disable too many features (cookies, JS, images) unless necessary.

You can inspect your headers with HTTP header checker and adjust. For high-security sites, consider:

• Using stable, realistic profiles (same UA + viewport + languages).
• Avoiding obviously automated patterns (e.g. requesting /robots.txt then hammering the site).

Behavior: delays, scrolling, and retries

Bots often request pages too fast or with no mouse/scroll. Add random delays between actions and, when it helps, simulate scroll or click so behaviour looks more human:

await page.goto(url, { waitUntil: 'networkidle' });
await page.waitForTimeout(1000 + Math.random() * 1500);

await page.mouse.move(200, 400, { steps: 10 });
await page.mouse.wheel(0, 600);
await page.waitForTimeout(800 + Math.random() * 1200);

Combine this with:

• Max request rate per IP / per account.
• Backoff and retry when you see 429/5xx or captchas.
