CAPTCHA Solver Speed Benchmark

Solve speed is a primary factor for CAPTCHA solving services used in high-volume automation. Every second of solve latency multiplies across thousands of daily tasks. This benchmark compares average solve times across major providers on the most commonly encountered CAPTCHA types.

Live rankings are updated from CaptchaRank's continuous benchmark pipeline. The data below reflects current benchmark state — check captcharank.com/solvers for the most recent values.

Overall Speed Ranking

The following table shows average solve time in seconds per provider, averaged across all supported types in the benchmark set:

Rank	Provider	Avg Solve Time	Benchmark Notes
1	CaptchaAI	8.7s	AI-first, consistent across types
2	Anti-Captcha	9.2s	Competitive; slightly variable on complex types
3	CapMonster Cloud	9.6s	Anti-Captcha-compatible; similar performance
4	CapSolver	~9–11s	Type-dependent variance
5	NopeCHA	~7–9s*	Fastest on supported types only
6	NextCaptcha	~8–11s	Competitive for core types
7	2Captcha	12.0s	Human-hybrid; slower but broadest coverage
8	DeathByCaptcha	~12–18s	Human-worker; slowest in benchmark set

NopeCHA is fastest within its supported type set, but covers fewer types than general-purpose providers.

Speed by CAPTCHA Type

Speed varies significantly by challenge complexity. The table below shows approximate ranges by CAPTCHA type:

reCAPTCHA v2 (Checkbox / Invisible)

Provider	Approx Time
CaptchaAI	7–12s
Anti-Captcha	8–14s
CapMonster Cloud	8–15s
NopeCHA	6–10s
2Captcha	12–18s

reCAPTCHA v2 is the most common benchmark type. AI-first providers outperform human-worker providers by 3–6 seconds on average.

reCAPTCHA v3

Provider	Approx Time
CaptchaAI	8–12s
Anti-Captcha	9–14s
2Captcha	10–16s

reCAPTCHA v3 challenges tend to take slightly longer than v2 across all providers.

Cloudflare Turnstile

Provider	Approx Time
CaptchaAI	6–10s
CapSolver	7–11s
Anti-Captcha	8–12s
2Captcha	9–14s

Turnstile solves are generally faster than reCAPTCHA v2 across all providers because the challenge structure is less complex.

hCaptcha

Provider	Approx Time
NopeCHA	5–8s
CaptchaAI	7–11s
Anti-Captcha	8–13s
2Captcha	10–16s

NopeCHA is notably fast on hCaptcha within its supported type set.

Image OCR / Text

Provider	Approx Time
CaptchaAI	3–6s
2Captcha	6–10s
DeathByCaptcha	8–14s

Image OCR is the fastest category across all providers due to simpler task structure.

What Affects Solve Time

Several variables affect observed solve time beyond the provider's raw performance:

1. Polling interval: Most providers require polling the /getTaskResult endpoint after submission. A 5-second polling interval adds up to 5 seconds of perceived latency per solve. Some integrations use 2–3 second polling to reduce this overhead.

2. CAPTCHA difficulty: Google adjusts reCAPTCHA challenge difficulty based on suspicious signals. High-difficulty challenge sets take longer for all providers.

3. Proxy quality: Providers that use proxy-based task types run the solve from a specific IP. Proxy quality affects the challenge difficulty served by Google.

4. Queue depth: At peak load, providers may queue tasks before processing begins. This adds pre-solve latency on top of the solve time itself.

5. Network latency: Time between your application and the provider's API. Providers with regional API endpoints can reduce this.

FAQ

Which provider is fastest overall? CaptchaAI has the lowest average solve time across all supported types in current benchmarks (8.7s). NopeCHA is faster within its limited supported type set.

Does faster solve time mean better overall quality? Not necessarily. Speed is one of four ranking dimensions on CaptchaRank. A fast provider with a low success rate produces more retries, which erases the speed advantage. CaptchaAI leads on both speed and success rate; 2Captcha is slower but offers broader type coverage.

How often does CaptchaRank update benchmark data? Benchmark data is updated continuously. Rankings reflect current performance, not historical averages.

Can I test solve speed before purchasing? Most providers offer trial deposits or free tier access. Testing with your target CAPTCHA type and volume profile gives the most accurate picture.
