Switch from DeathByCaptcha to CaptchaAI for modern coverage and a simpler API.
DeathByCaptcha is the oldest solver, but it stops at classic image and reCAPTCHA v2. CaptchaAI adds Cloudflare, reCAPTCHA Enterprise, GeeTest and BLS — with a plain API-key REST integration (no SDK) and thread-based pricing that flattens at scale.
# DeathByCaptcha: username/password + SDK client - client = deathbycaptcha.HttpClient("USER", "PASS") - captcha = client.decode(type=4, token_params={ - "googlekey": sitekey, "pageurl": url}, timeout=180) # CaptchaAI: API key + plain REST, no SDK + requests.post("https://ocr.captchaai.com/in.php", data={ + "key": KEY, "method": "userrecaptcha", + "googlekey": sitekey, "pageurl": url})
Drop the SDK dependency — submit a task and poll for the result over plain HTTP.
Solves the full modern CAPTCHA stack
Two things developers reconsider
DeathByCaptcha is a veteran. Modern sites moved past it.
DeathByCaptcha built its reputation on classic image CAPTCHAs and still handles them well. But it doesn't support Cloudflare, reCAPTCHA Enterprise, GeeTest or BLS, its hybrid human-solver model adds latency on token CAPTCHAs, and its per-solve billing runs higher than newer services at every tier. Here's what changes on CaptchaAI.
Why teams move
Five reasons developers switch from DeathByCaptcha
1. Modern CAPTCHA types
Cloudflare Turnstile and full Challenge, reCAPTCHA Enterprise, GeeTest v3 and BLS — types DeathByCaptcha doesn't support at all.
2. Simpler auth, no SDK
An API key and plain REST calls replace username/password auth and the DeathByCaptcha client library. One less dependency to ship.
3. More consistent timing
DeathByCaptcha's hybrid human-solver pool adds latency, especially on token CAPTCHAs. CaptchaAI's AI-led pipeline returns results in tighter ranges.
4. Lower cost at every tier
Thread pricing with unlimited solves per thread, plus a $1 minimum deposit versus DeathByCaptcha's $6.90. The gap widens as volume grows.
5. Retries at no extra cost
Failed solves are retried automatically inside your thread budget — you're not billed again for a re-attempt.
Free trial to test first
Validate CaptchaAI on your own targets with a 3-day free trial, 5 threads — DeathByCaptcha has no free trial.
Migration
Drop the SDK, keep the workflow
DeathByCaptcha wraps its API in an official client library with username/password auth. CaptchaAI uses a plain REST endpoint and an API key — so migration mostly means removing a dependency and parsing a pipe-delimited response.
- Replace
HttpClient("user","pass")with your CaptchaAIkey client.decode(...)→POST in.php, then pollres.php?action=gettype=4(reCAPTCHA) →method=userrecaptcha- Parse the pipe-delimited REST response instead of the SDK's result object
import requests, time API_KEY = "YOUR_CAPTCHAAI_KEY" API_URL = "https://ocr.captchaai.com" def solve_recaptcha(sitekey, pageurl): # Submit (replaces client.decode) r = requests.post(f"{API_URL}/in.php", data={ "key": API_KEY, "method": "userrecaptcha", "googlekey": sitekey, "pageurl": pageurl, "json": 1, }) task_id = r.json()["request"] # Poll for the result (no SDK, no socket) for _ in range(60): time.sleep(5) res = requests.get(f"{API_URL}/res.php", params={ "key": API_KEY, "action": "get", "id": task_id, "json": 1, }).json() if res["request"] != "CAPCHA_NOT_READY": return res["request"] raise TimeoutError("Solve timeout") # Start a free trial at captchaai.com/trial to get your API key

CaptchaAI vs DeathByCaptcha
Capability coverage. Solve metrics are benchmarked — see the evidence note.
| Feature | CaptchaAI | DeathByCaptcha |
|---|---|---|
| reCAPTCHA v2 | ||
| reCAPTCHA v3 | Limited | |
| reCAPTCHA Enterprise | ||
| Cloudflare Turnstile | ||
| Cloudflare Challenge (full page) | ||
| GeeTest | v3 | |
| BLS CAPTCHA | ||
| Image / OCR types | 27,500+ | |
| Authentication | API key | Username / password |
| API style | REST (no SDK needed) | REST + Socket (SDK) |
| Billing model | Per thread (unlimited solves) | Per solve |
| Minimum deposit | $1 | $6.90 |
| Free trial |
Where DeathByCaptcha may fit: if you only solve classic image CAPTCHAs and already have an integration built on its SDK, or you specifically need its socket API, staying put can be reasonable. For any modern CAPTCHA type, simpler auth, and lower cost at scale, CaptchaAI is the stronger match.
Illustrative pipeline
What changes day to day
Representative example for a high-volume reCAPTCHA pipeline. Your numbers depend on target sites and proxy quality.
Before — DeathByCaptcha (SDK, per-solve)
After — CaptchaAI (REST, thread-based)
Pricing
Pay per thread. Unlimited solves.
A thread is one in-flight CAPTCHA. It frees up the moment it finishes — so you size by concurrency, not by solve count. No per-CAPTCHA fees, no type surcharges.
Larger plans — CORPORATE ($240/mo, 150 threads), ENTERPRISE ($300/mo, 200 threads), and VIP tiers up to 5,000 threads. See full pricing →
Where the gap widens at scale
| Monthly reCAPTCHA v2 volume | DeathByCaptcha (per-solve) | CaptchaAI plan | CaptchaAI cost | You save |
|---|---|---|---|---|
| 10,000 solves | ~$29 | BASIC (5 threads) | $15 | ~48% |
| 100,000 solves | ~$289 | BASIC (5 threads) | $15 | ~95% |
| 1,000,000 solves | ~$2,890 | ADVANCE (50 threads) | $90 | ~97% |
| 10,000,000 solves | ~$28,900 | ENTERPRISE (200 threads) | $300 | ~99% |
Illustrative, using DeathByCaptcha's published reCAPTCHA v2 rate (~$2.89 / 1,000, accessed May 2026) against CaptchaAI plans sized to peak concurrency. The thread model wins because once threads are paid for, additional volume runs through them at zero marginal cost. Confirm live numbers on captchaai.com/#pricing-plans.
FAQ
Frequently Asked Questions
Yes. You replace the DeathByCaptcha client library and username/password auth with a CaptchaAI API key and plain REST calls to in.php / res.php. The workflow is the same (submit a task, poll for the result), and you remove the SDK dependency entirely.
For a single integration point it is usually quick — swap client.decode(...) for a POST to in.php, change type=4 to method=userrecaptcha, poll res.php, and parse the pipe-delimited response instead of the SDK's result object.
Yes. Every new account gets a 3-day free trial with 5 threads — claim it at captchaai.com/trial. DeathByCaptcha has no free trial, so this is a no-cost way to compare on your own targets before you move production traffic.
If you only solve classic image CAPTCHAs and already have a working integration on its SDK, or you specifically need its socket API, staying put can be reasonable. DeathByCaptcha's image/OCR has a long track record. Run CaptchaAI on a free trial and compare for your use case.
In published rates, yes — DeathByCaptcha bills per solve (reCAPTCHA v2 around $2.89/1,000) with a $6.90 minimum deposit, while CaptchaAI bills per thread with unlimited solves and a $1 minimum. The thread model's advantage grows with volume. Compare your monthly solve count against a thread tier on the pricing page.
CaptchaAI covers Cloudflare Turnstile and the full-page Challenge, reCAPTCHA Enterprise, GeeTest v3, BLS multi-image CAPTCHA, and a broad 27,500+ image/OCR set. DeathByCaptcha focuses on classic image CAPTCHAs and reCAPTCHA v2 and doesn't support these modern types.

Evidence & sources
Capability coverage, authentication model, and the SDK/socket details are from CaptchaAI's published supported CAPTCHA types (api-docs) and the comparison at blog.captchaai.com/captchaai-vs-deathbycaptcha. DeathByCaptcha's lack of Cloudflare, reCAPTCHA Enterprise, GeeTest and BLS support, its username/password auth, and its $6.90 minimum deposit are stated there.
Cost examples use published CaptchaAI plans (captchaai.com/#pricing-plans) and DeathByCaptcha's published reCAPTCHA v2 rate (~$2.89 / 1,000), both accessed May 2026. Pricing and supported types change over time — confirm current numbers before relying on them. Solve times are representative, not guaranteed; results vary by target site and proxy quality.
