GeeTest vs Cloudflare Turnstile: CAPTCHA Comparison

Two different approaches to bot protection. GeeTest uses interactive puzzle challenges; Turnstile uses invisible browser verification. Here's how they compare.

Architecture Comparison

Detection Method

GeeTest

• Tracks mouse movement patterns during slide/click
• Analyzes drag speed, acceleration, trajectory
• Uses device fingerprinting
• Challenge difficulty adapts to perceived risk

Cloudflare Turnstile

• Runs invisible browser challenges
• Checks browser APIs and environment
• Validates TLS fingerprint
• Uses Cloudflare's threat intelligence network
• No user interaction for most visitors

Solving with CaptchaAI

GeeTest

import requests
import time
import os

API_KEY = os.environ["CAPTCHAAI_API_KEY"]


def solve_geetest(gt, challenge, pageurl):
    resp = requests.post("https://ocr.captchaai.com/in.php", data={
        "key": API_KEY,
        "method": "geetest",
        "gt": gt,
        "challenge": challenge,
        "pageurl": pageurl,
        "json": 1,
    }, timeout=30)
    task_id = resp.json()["request"]

    time.sleep(10)
    for _ in range(30):
        resp = requests.get("https://ocr.captchaai.com/res.php", params={
            "key": API_KEY, "action": "get",
            "id": task_id, "json": 1,
        }, timeout=15)
        data = resp.json()
        if data.get("status") == 1:
            return data["request"]
        if data["request"] != "CAPCHA_NOT_READY":
            raise RuntimeError(data["request"])
        time.sleep(5)

    raise TimeoutError("GeeTest timeout")

Cloudflare Turnstile

def solve_turnstile(sitekey, pageurl):
    resp = requests.post("https://ocr.captchaai.com/in.php", data={
        "key": API_KEY,
        "method": "turnstile",
        "sitekey": sitekey,
        "pageurl": pageurl,
        "json": 1,
    }, timeout=30)
    task_id = resp.json()["request"]

    time.sleep(5)
    for _ in range(24):
        resp = requests.get("https://ocr.captchaai.com/res.php", params={
            "key": API_KEY, "action": "get",
            "id": task_id, "json": 1,
        }, timeout=15)
        data = resp.json()
        if data.get("status") == 1:
            return data["request"]
        if data["request"] != "CAPCHA_NOT_READY":
            raise RuntimeError(data["request"])
        time.sleep(5)

    raise TimeoutError("Turnstile timeout")

Performance Comparison

Where Each Is Used

GeeTest Common Sites

• Chinese web services and platforms
• Gaming sites
• Financial services in Asia-Pacific
• High-security login pages

Turnstile Common Sites

• Sites using Cloudflare CDN
• SaaS login pages
• Contact forms
• API-protected endpoints
• Sites migrating from reCAPTCHA

Which Is Harder to Solve?

Neither is harder for CaptchaAI — both solve at 100%. The practical differences:

• GeeTest requires extracting a fresh challenge parameter before each solve, adding complexity to the scraping flow
• Turnstile has a static sitekey that doesn't change, making parameter extraction simpler
• GeeTest tokens expire faster (60-120s vs 300s), requiring tighter timing
• Turnstile is more common on Western websites; GeeTest dominates in Asia

Decision Matrix

FAQ

Can a site use both GeeTest and Turnstile?

Extremely unlikely. Sites choose one CAPTCHA provider. However, different pages on the same domain could theoretically use different providers.

Which is cheaper to solve?

Both are priced similarly on CaptchaAI. Turnstile may be marginally cheaper in practice because its faster solve time means fewer polling requests.

Which is replacing the other?

Neither directly. Turnstile is gaining adoption as a reCAPTCHA replacement. GeeTest remains strong in its existing markets (China, gaming, finance).
