headed playwright chrome with --disable-blink-features=AutomationControlled not detected

[Le0Developer]

Headed chromium is only detected by navigator.webdriver, which can be disabled with the --disable-blink-features=AutomationControlled launch option.

Technically this also applies to Webkit, as there only navigator.webdriver is detected too, but I haven't found a launch option to do that yet. (It can still be done with stealth scripts but those are easier to detect)

Reproduction code:

from playwright.sync_api import sync_playwright, TimeoutError

with sync_playwright() as p:
    print("Testing chromium")
    # disable headless & navigator.webdriver
    browser = p.chromium.launch(headless=False, args=["--disable-blink-features=AutomationControlled"])
    page = browser.new_page()
    page.goto('https://fingerprintjs.github.io/BotD/main/')
    try:
        handle = page.wait_for_selector("#result.result-detected", timeout=1_000)
    except TimeoutError:
        print("Chromium is undetected.")
    else:
        print("Chromium is detected.")

    # input("press enter to continue> ")  # just incase you want to see the site yk
    browser.close()

Hi @Le0Developer.

You are right, that detecting webdriver can be bypassed using flags. We won't fix it, because it's not the scope of BotD OSS. If you want more sophisticated bot detection, see our BotD Pro https://fingerprint.com/products/bot-detection/. However, it cannot detect this particular flag.

I'm closing for now, if you have any other questions, lmk.
