Speed Comparison (average solve time)

CAPTCHA Type	CaptchaAI	2Captcha	Anti-Captcha	CapSolver	DBC
Image/OCR	~5s	~8s	~8s	~5s	~12s
reCAPTCHA v2	~12s	~20s	~20s	~15s	~45s
reCAPTCHA v3	~8s	~15s	~12s	~10s	~45s+
Turnstile	~10s	~15s	~15s	~12s	N/A

CaptchaAI delivers the fastest solve times, particularly for token-based CAPTCHAs. Speed differences compound significantly at high volumes.

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.

Developer Experience

Feature	CaptchaAI	2Captcha	Anti-Captcha	CapSolver
Free trial	✅	❌	❌	✅
API docs quality	Strong	Strong	Strong	Good
Official SDKs	Python, JS	Python, JS, PHP	Python, JS, Go	Python, JS, Go
Dashboard	Balance, stats	Balance, stats, logs	Balance, stats, logs	Balance, stats
Callback support	✅	✅	✅	✅

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 offers the lowest per-solve pricing across all major CAPTCHA types. For image CAPTCHAs, rates start at $0.50 per 1,000 solves.

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.

Are CAPTCHA solving services legal?

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?
