How to Make Playwright Undetectable

To make Playwright undetectable, you must customize browser settings, spoof user agent strings, disable automation flags, and use realistic interaction patterns. By doing this, you can reduce the likelihood of websites detecting your automated scripts.

How to Make Playwright Undetectable

We can see an example of implementing this in a Playwright script: 

const { chromium } = require('playwright');

(async () => {
    const browser = await chromium.launch({
        headless: false,
        args: ['--disable-blink-features=AutomationControlled']
    });
    const context = await browser.newContext({
        userAgent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36',
        viewport: { width: 1280, height: 720 },
        deviceScaleFactor: 1,
    });
    const page = await context.newPage();
    await page.goto('https://cnn.com');

    await browser.close();
})();

  • Disable Automation Flags: We can use the argument to remove the automation flag, which can help prevent detection.--disable-blink-features=AutomationControlled

  • Set Realistic Viewport and Device Characteristics: Configure the browser context to match typical user settings. We will set the viewport to a typical display so we don't raise any flags.

  • Modify User Agent String: We can use different user agent strings to appear as a more commonly used browser.
