Playwright CAPTCHA Handling with CaptchaAI

Playwright provides reliable browser automation across Chromium, Firefox, and WebKit. When target pages serve CAPTCHAs, CaptchaAI solves them server-side while Playwright handles the browser interaction.

Requirements

Requirement Details
Python pip install playwright requests then playwright install
Node.js npm install playwright axios
CaptchaAI API key From captchaai.com

Python: Playwright + CaptchaAI

Setup

from playwright.sync_api import sync_playwright
import requests
import time

API_KEY = "YOUR_API_KEY"

def solve_recaptcha(site_key, page_url):
    resp = requests.get("https://ocr.captchaai.com/in.php", params={
        "key": API_KEY,
        "method": "userrecaptcha",
        "googlekey": site_key,
        "pageurl": page_url
    })
    if not resp.text.startswith("OK|"):
        raise Exception(resp.text)
    task_id = resp.text.split("|")[1]

    for _ in range(60):
        time.sleep(5)
        result = requests.get("https://ocr.captchaai.com/res.php", params={
            "key": API_KEY, "action": "get", "id": task_id
        })
        if result.text == "CAPCHA_NOT_READY": continue
        if result.text.startswith("OK|"): return result.text.split("|")[1]
        raise Exception(result.text)
    raise TimeoutError()

Full Example

        # Fill login form
        page.fill("#username", username)
        page.fill("#password", password)

        # Check for reCAPTCHA
        recaptcha = page.query_selector(".g-recaptcha")
        if recaptcha:
            site_key = recaptcha.get_attribute("data-sitekey")
            print(f"Solving reCAPTCHA: {site_key}")

            token = solve_recaptcha(site_key, page.url)

            # Inject token
            page.evaluate(f"""
                document.getElementById('g-recaptcha-response').innerHTML = '{token}';
                document.getElementById('g-recaptcha-response').style.display = '';
            """)

        # Submit
        page.click('button[type="submit"]')
        page.wait_for_load_state("networkidle")

        print(f"Current URL: {page.url}")
        content = page.content()

        browser.close()
        return content

result = login_with_captcha(
    "https://example.com/login",
    "user@example.com",
    "password123"
)

Playwright vs Selenium vs Puppeteer

Feature Playwright Selenium Puppeteer
Languages Python, Node.js, C#, Java Python, Java, C#, Ruby, JS Node.js
Browsers Chromium, Firefox, WebKit Chrome, Firefox, Edge, Safari Chromium
Auto-wait ✅ Built-in ❌ Manual waits ⚠️ Partial
Network interception ⚠️ Limited
CaptchaAI integration ✅ Same API ✅ Same API ✅ Same API

CaptchaAI works identically with all three — extract the site key, solve via API, inject the token.

Troubleshooting

Issue Fix
page.query_selector returns null CAPTCHA loads dynamically; use page.wait_for_selector()
Token injection doesn't work Check if the response textarea has a different ID
Playwright crashes in Docker Install browser dependencies: playwright install-deps
CAPTCHA reappears after solving Site may require callback execution; trigger it via page.evaluate()

FAQ

Does Playwright's auto-wait help with CAPTCHAs?

Playwright's auto-wait ensures elements are visible before interacting, but it won't solve CAPTCHAs. You need CaptchaAI for the actual solving.

Can I use Playwright with all CAPTCHA types?

Yes. CaptchaAI handles the solving via API — Playwright just needs to extract the site key and inject the token. This works for reCAPTCHA, Turnstile, hCaptcha, and all other supported types.

Is Playwright better than Selenium for CAPTCHA automation?

Playwright's built-in auto-wait and better API design make CAPTCHA workflows more reliable. The CaptchaAI integration is identical for both.
