Pricing Comparison

CaptchaAI uses thread-based plans with unlimited solves per thread. The other services use per-solve pricing. The table below shows CaptchaAI's effective per-1K cost at typical thread utilization alongside published per-1K rates from the others.

CAPTCHA Type CaptchaAI (effective per 1K) 2Captcha Anti-Captcha CapSolver DBC
Image/OCR $0.50 $0.70 $0.70 $0.80 $1.39
reCAPTCHA v2 $1.00 $1.45 $1.80 $1.50 $2.89
reCAPTCHA v3 $1.20 $1.45 $2.00 $1.80 $5.00+
Turnstile $1.00 $1.45 $2.00 $1.50 N/A
hCaptcha $1.00 $1.45 $1.80 $1.50 N/A

Prices shown are starting rates. CaptchaAI's effective per-solve cost drops further as you push more volume through each thread.

Pricing at scale

Every service in this comparison except CaptchaAI bills per solve, so the monthly bill scales linearly with traffic. CaptchaAI bills the thread — every CAPTCHA cleared on a running thread is free, so the effective per-1K cost falls as utilization rises. Using each service's published reCAPTCHA v2 rate against CaptchaAI plans sized to peak concurrency:

Monthly reCAPTCHA v2 volume 2Captcha Anti-Captcha CapSolver DBC CaptchaAI plan CaptchaAI cost
10,000 solves ~$15 ~$18 ~$15 ~$29 BASIC (5 threads) $15
100,000 solves ~$145 ~$180 ~$150 ~$289 BASIC (5 threads) $15
1,000,000 solves ~$1,450 ~$1,800 ~$1,500 ~$2,890 ADVANCE (50 threads) $90
10,000,000 solves ~$14,500 ~$18,000 ~$15,000 ~$28,900 ENTERPRISE (200 threads) $300

Plan threads to match peak concurrency, then push unlimited volume through them — that structural difference is what makes the gap widen instead of close as you scale.

Speed Comparison (typical)

Image/OCR <0.5s 5–10s 5–10s 5–10s 10–15s
reCAPTCHA v2 <60s 20–60s 15–25s 15–30s 30–60s

Turnstile <10s 15–30s 15–25s 10–20s N/A

API Design and Integration

REST-Based (CaptchaAI, 2Captcha)

Submit via GET parameters, poll via GET. Simplest to integrate — testable from a browser URL bar or curl:

# CaptchaAI submit
resp = requests.get("https://ocr.captchaai.com/in.php", params={
    "key": "YOUR_API_KEY",
    "method": "userrecaptcha",
    "googlekey": "SITE_KEY",
    "pageurl": "https://example.com"
})
task_id = resp.text.split("|")[1]

# CaptchaAI poll
result = requests.get("https://ocr.captchaai.com/res.php", params={
    "key": "YOUR_API_KEY",
    "action": "get",
    "id": task_id
})

JSON-Based (Anti-Captcha, CapSolver)

Submit via JSON POST with typed task objects:

# Anti-Captcha submit
resp = requests.post("https://api.anti-captcha.com/createTask", json={
    "clientKey": "YOUR_KEY",
    "task": {
        "type": "RecaptchaV2TaskProxyless",
        "websiteURL": "https://example.com",
        "websiteKey": "SITE_KEY"
    }
})

Both patterns follow the same workflow: submit task → poll for result. REST-based APIs require fewer lines of code and no request body construction.

Accuracy and Reliability

Metric CaptchaAI 2Captcha Anti-Captcha CapSolver DBC
Success rate 99%+ 99% 99% 99% ~90%
Uptime 99.9%+ 99.9% 99.9% 99.5% 99%
Auto-retry ✅ ✅ ✅ ✅ ❌
Refund on failure ✅ ✅ ✅ ✅ ✅

All modern services maintain high accuracy on standard CAPTCHAs. DeathByCaptcha's lower accuracy reflects its older human-solver infrastructure.

Which Service Should You Choose?

Choose CaptchaAI if:

  • You want the lowest pricing across all CAPTCHA types
  • You need BLS CAPTCHA or Cloudflare Challenge support
  • Speed is critical (fastest average solve times)
  • You prefer a simple REST API without SDK dependencies
  • You want a free trial to test before paying

Choose 2Captcha if:

  • You need an established service with extensive documentation
  • You want PHP SDK support
  • CaptchaAI-compatible API format (easiest migration path)

Choose Anti-Captcha if:

  • Your team standardized on JSON-based APIs
  • You need Go SDK support
  • You're solving standard types only (reCAPTCHA, hCaptcha)

Choose CapSolver if:

  • You need AWS WAF or DataDome CAPTCHA support
  • You want a modern JSON API with competitive pricing
  • You need Cloudflare Challenge support (only CaptchaAI and CapSolver offer this)

Avoid DeathByCaptcha if:

  • You need any CAPTCHA type besides image and reCAPTCHA v2
  • Speed matters — their solve times are 3-4x slower
  • Accuracy above 95% is required for token-based CAPTCHAs

FAQ

Which CAPTCHA solver is cheapest?

CaptchaAI uses thread-based plans with unlimited solves per thread — starting at $15/month (BASIC, 5 threads) up to $300/month (ENTERPRISE, 200 threads). Because every CAPTCHA cleared on a running thread is free, the effective per-1K cost falls as utilization rises and undercuts every per-solve provider in this comparison at moderate to high volume. See CaptchaAI Pricing for the full plan table.

Do these services work with Selenium and Puppeteer?

Yes. All services listed are API-based — you submit CAPTCHA parameters from your browser automation script and inject the returned token. They work with any browser automation framework.

CAPTCHA solving services are legal tools. How they're used depends on the specific use case and the target website's terms of service. Common legitimate applications include accessibility testing, QA automation, and authorized data collection.

Can I use multiple services as fallbacks?

Yes. A common pattern is to use CaptchaAI as the primary solver and a secondary service as fallback. Since all services use similar submit/poll patterns, implementing fallback logic requires minimal code.

What's the difference between free and paid solvers?
