Quick Comparison

CAPTCHA Type Support

Where CaptchaAI Leads

• Cloudflare Challenge — Full Cloudflare Challenge page solving. CapMonster only supports Turnstile tokens.
• Image CAPTCHA breadth — 27,500+ image CAPTCHA types recognized by CaptchaAI's OCR engine.
• Turnstile success rate — CaptchaAI reports 100% success on Turnstile tokens.

Where CapMonster Cloud Performs

• Local software option — CapMonster offers a desktop version for self-hosted solving (CPU-based OCR). CaptchaAI is cloud-only.
• Batch processing — CapMonster has built-in task queuing for batch submissions.

API Design

CaptchaAI uses a 2Captcha-compatible API, making migration simple if you're coming from 2Captcha:

# CaptchaAI — 2Captcha-compatible API
import requests

# Submit task
resp = requests.post("https://ocr.captchaai.com/in.php", data={
    "key": "YOUR_API_KEY",
    "method": "userrecaptcha",
    "googlekey": "SITE_KEY",
    "pageurl": "https://example.com",
    "json": 1,
})
task_id = resp.json()["request"]

# Poll result
import time
for _ in range(60):
    time.sleep(5)
    result = requests.get("https://ocr.captchaai.com/res.php", params={
        "key": "YOUR_API_KEY",
        "action": "get",
        "id": task_id,
        "json": 1,
    })
    data = result.json()
    if data["request"] != "CAPCHA_NOT_READY":
        print(f"Token: {data['request']}")
        break

# CapMonster Cloud — Custom API
resp = requests.post("https://api.capmonster.cloud/createTask", json={
    "clientKey": "YOUR_API_KEY",
    "task": {
        "type": "RecaptchaV2TaskProxyless",
        "websiteURL": "https://example.com",
        "websiteKey": "SITE_KEY",
    },
})
task_id = resp.json()["taskId"]

# Poll result
for _ in range(60):
    time.sleep(5)
    result = requests.post("https://api.capmonster.cloud/getTaskResult", json={
        "clientKey": "YOUR_API_KEY",
        "taskId": task_id,
    })
    data = result.json()
    if data["status"] == "ready":
        print(f"Token: {data['solution']['gRecaptchaResponse']}")
        break

Key API difference: CaptchaAI's 2Captcha-compatible format means you can switch from 2Captcha by changing only the domain. CapMonster uses a different request/response format.

Success Rates

Pricing

CaptchaAI uses thread-based plans with unlimited solves per thread per month, starting at $15/month. CapMonster Cloud charges per solve. The table below puts CaptchaAI's effective per-1K cost (at typical thread utilization) next to CapMonster's published per-1K rates:

Pricing at scale

CapMonster Cloud bills per solve, so the bill scales linearly with traffic. CaptchaAI bills the thread — once a thread is running, every CAPTCHA cleared on it is free, so the effective per-1K cost falls as utilization rises. Using CapMonster's reCAPTCHA v2 rate (~$1.00 / 1,000 solves) against CaptchaAI plans sized to peak concurrency:

Above ~50K solves/month the thread-based model is structurally cheaper than per-solve billing, and the gap widens every time you push more volume through the same threads.

Speed Comparison

Both services offer comparable speed. CapMonster's local software can be faster for image OCR since it runs locally.
