BestCaptcha Solving Services: Features, Pros, Cons & Comparison

Captchas tend to become a problem only after the rest of the automation is already working. A browser has loaded the page, completed several steps, and is ready to continue — then a challenge stops the flow.

This happens in end-to-end tests, browser-based QA, monitoring, form validation, and automated data collection.

For developers, the useful metric is not just response time. A fast answer does not help much if the site rejects it and the browser has to repeat part of the workflow.

Among the services covered here, 2Captcha has the strongest overall results in the available data. Other providers still lead specific captcha types, especially Turnstile, Arkose/FunCaptcha, and image captcha.

Captcha solving also sits inside a larger testing stack. DevOpsSchool’s guide to test automation tools covers the broader tools used around automated web and application testing.

This comparison includes:

• 2Captcha
• SolveCaptcha
• Anti-Captcha
• CapMonster Cloud
• CapSolver
• DeathByCaptcha

Performance figures come from the monthly CaptchaTheCat benchmark. The dataset covers correctness, returned results, response time, and several common captcha types.

1. 2Captcha

2Captcha is the most consistent service in the dataset.

Its strongest results are on reCAPTCHA. It reached 99% correctness on hard, moderate, and easy reCAPTCHA v2 tests, then finished first on reCAPTCHA v3 at 97%.

Amazon captcha was another strong result:

• 98% correctness
• 99% received
• 33-second average response time

SolveCaptcha posted the same Amazon numbers.

2Captcha is not first everywhere. SolveCaptcha leads Arkose/FunCaptcha and Cloudflare Challenge. Anti-Captcha performs better on Turnstile and image captcha.

For mixed workloads, the broader consistency is useful. A single application may encounter several captcha types, and maintaining one capable integration is simpler than routing every challenge to a different provider.

The service also has a mature developer ecosystem with API access, SDKs, examples, and support for a wide range of captcha types.

Pros

• 99% correctness across all reCAPTCHA v2 tests
• Best reCAPTCHA v3 result
• Broad captcha coverage
• Mature API and SDK ecosystem

Cons

• Several competitors are faster
• Other providers lead some individual captcha types

2. SolveCaptcha

The overall averages barely separate SolveCaptcha from 2Captcha.

The difference in correctness is 0.12 percentage points. SolveCaptcha returned slightly more results and was marginally faster.

Arkose/FunCaptcha is where it moves ahead more clearly. SolveCaptcha reached 93% correctness, returned results for 89% of tasks, and averaged 50 seconds. 2Captcha recorded 92%, 86%, and 55 seconds.

Cloudflare Challenge was another win: 97% correctness versus 95% for 2Captcha. Both returned results for every task and averaged 14 seconds.

Amazon captcha ended in a tie at 98% correctness, 99% received, and 33 seconds.

For workloads that regularly encounter Arkose/FunCaptcha or Cloudflare Challenge, SolveCaptcha is one of the strongest options here.

Pros

• Very close to 2Captcha overall
• Best Arkose/FunCaptcha result
• Best Cloudflare Challenge result

Cons

• Marginally lower average correctness
• Smaller integration ecosystem

3. Anti-Captcha

Turnstile is where Anti-Captcha clearly stands out.

It reached:

• 99% correctness
• 100% received
• 29-second average response time

That is the highest Turnstile correctness in the comparison.

It also led image captcha at 71%. SolveCaptcha followed at 63%, with 2Captcha at 61%.

reCAPTCHA v2 was much weaker. Anti-Captcha stayed between 45% and 47% correctness across hard, moderate, and easy tests.

For Turnstile-heavy or image-heavy workloads, the numbers are strong. For reCAPTCHA v2, they are not.

Pros

• Best Turnstile correctness
• Best image captcha result

Cons

• Relatively slow Turnstile response
• Weak reCAPTCHA v2 performance

4. CapMonster Cloud

The number that catches the eye here is 4.26 seconds.

That is CapMonster Cloud’s average response time on reCAPTCHA v3, where it still reached 96% correctness.

2Captcha leads reCAPTCHA v3 at 97%, but averages 19 seconds. The accuracy gap is only one percentage point.

Amazon captcha shows a similar tradeoff: 96% correctness in 17 seconds versus 98% in 33 seconds for 2Captcha and SolveCaptcha.

The Arkose/FunCaptcha row is much less attractive. CapMonster Cloud reached 88% correctness, but only 46% of submitted tasks produced a returned result. Image captcha correctness was 40%.

Pros

• Very fast reCAPTCHA v3
• Strong Turnstile performance
• Good Amazon captcha result

Cons

• Only 46% received on Arkose/FunCaptcha
• Weak image captcha result
• Performance varies considerably by challenge type

5. CapSolver

CapSolver’s benchmark is dominated by speed.

Its fastest rows include:

• image captcha — 0.70 seconds
• Amazon captcha — 4.25 seconds
• reCAPTCHA v3 — 5.84 seconds
• Cloudflare Turnstile — 10 seconds

On reCAPTCHA v3, CapSolver reached 95% correctness. That is two percentage points behind 2Captcha, but the response time drops from 19 seconds to 5.84 seconds.

Turnstile also looks competitive at 94% correctness, 100% received, and 10 seconds.

Amazon is where that speed advantage starts to look much less useful. The 4.25-second result is impressive at first glance, but correctness was only 44%.

Image captcha goes further: 0.70 seconds and 15% correctness.

Pros

• Very low latency
• Competitive reCAPTCHA v3 performance

Cons

• 44% correctness on Amazon captcha
• 15% correctness on image captcha
• Results vary sharply by challenge type

6. DeathByCaptcha

There is not enough category-level data here for a useful Pros/Cons breakdown.

DeathByCaptcha ranks sixth in the available comparison, but the source does not provide the same detailed rows available for most of the other providers.

That makes it difficult to compare its reCAPTCHA, Turnstile, Amazon, Arkose, or image captcha performance directly.

For teams considering it, separate testing against the real workload would be more useful than drawing conclusions from the limited data.

Captcha solving services comparison

For projects that see only one or two captcha types, this table is more useful than the overall ranking.

reCAPTCHA favors 2Captcha. SolveCaptcha has the stronger Arkose/FunCaptcha and Cloudflare Challenge results. Anti-Captcha leads Turnstile and image captcha.

Accuracy vs. speed in automated testing

A solver is only one step in a longer browser process.

By the time a captcha appears, the application may already have opened a browser, loaded several pages, signed in, filled a form, and sent multiple requests.

If the answer fails, some of that work may need to happen again.

Amazon captcha makes the tradeoff easy to see. CapSolver averages 4.25 seconds, while 2Captcha and SolveCaptcha average 33 seconds. But their correctness rates are 44% and 98%.

reCAPTCHA v3 looks different. 2Captcha reaches 97%, CapMonster Cloud 96%, and CapSolver 95%. In that case, the shorter response time may be worth the small drop in correctness.

The better metrics sit at workflow level:

• completed jobs per hour
• retries per successful job
• failures caused by incorrect captcha answers
• browser session restarts
• proxy traffic
• total completion time

A faster solver is useful only if the complete job also finishes faster.

Which service fits which workload?

For mixed workloads and reCAPTCHA-heavy automation, 2Captcha is the strongest starting point. It leads both reCAPTCHA versions and stays competitive across the broader dataset.

SolveCaptcha is more interesting when Arkose/FunCaptcha or Cloudflare Challenge appears regularly. It leads both categories in the available benchmark.

Turnstile points toward Anti-Captcha if correctness is the priority. CapMonster Cloud gives up two percentage points but cuts the average response from 29 seconds to 11.

When latency matters most, CapMonster Cloud and CapSolver deserve testing first. The tradeoff is worthwhile only where their correctness remains close to the leader.

Before you integrate a solver

Benchmark numbers help narrow the shortlist. The integration itself still matters.

Start with API and SDK quality. Task submission, result retrieval, timeouts, and errors should fit the application’s existing flow without forcing special handling everywhere. Maintained SDKs can save a fair amount of work when several languages or services are involved.

Captcha coverage matters just as much. The benchmark shows how quickly the ranking changes between reCAPTCHA, Turnstile, Arkose, Amazon, and image captcha.

Proxy and session handling are another practical issue. IP address, region, session state, and other request context can affect the challenge, so the solver has to fit the network setup used by the browser.

Finally, test retries in the real workflow. A timeout, rejected answer, API error, and lost browser session are different failures. Treating all of them as another captcha request can waste time and traffic.

Public benchmark data is useful for choosing candidates. The final test should use the same proxies, browser setup, regions, and session flow as the real application.

Conclusion

The benchmark is most useful as a shortlist. 2Captcha is the strongest general-purpose option, but individual captcha types can point elsewhere. Test the two or three providers that perform best for the challenges in your workflow, then compare completed jobs rather than API response time alone.

FAQs
