6 Best Captcha Solving Services: Accuracy, Speed, and Reliability

headline for captcha solving services

Response time is the easiest captcha solving metric to compare, but it is rarely the most useful one on its own. A quick answer only helps when the target site accepts it.

A rejected token can trigger another challenge, interrupt a browser session, consume more proxy traffic, and keep a worker busy while the workflow starts again. In practice, a solver that answers in less than a second may complete fewer tasks than one that takes 18 seconds but returns correct results more often.

This comparison covers 2Captcha, SolveCaptcha, Anti-Captcha, CapMonster Cloud, CapSolver, and DeathByCaptcha. The figures come from a monthly CaptchaTheCat benchmark and include correctness, received rate, average response time, captcha coverage, and integration support.

The results do not point to one winner for every workload. 2Captcha provides the best overall balance, while several competitors lead individual captcha categories or offer a stronger speed-to-accuracy tradeoff in specific cases.

Key takeaways

  • 2Captcha ranked first overall, combining strong benchmark results with broad coverage, documentation, SDKs, GitHub resources, and fallback handling.
  • SolveCaptcha ranked second and led Arkose/FunCaptcha and Cloudflare Challenge.
  • Anti-Captcha posted the best correctness figures for Cloudflare Turnstile and image captcha.
  • 2Captcha and SolveCaptcha tied on Amazon captcha across correctness, received rate, and response time.
  • CapMonster Cloud and CapSolver were often faster, but their accuracy varied sharply by captcha type.
  • The most suitable provider depends on the challenge mix and the cost of repeating a failed workflow.

How the comparison works

Monthly data is more useful here than a daily snapshot. A single day can be affected by temporary provider problems, changes in challenge configuration, or short periods of high load.

MetricMeaningHow to read it
Correctly solvedShare of tasks solved correctlyMain quality metric
ReceivedShare of tasks that returned an answerAvailability, not guaranteed success
Average recognition timeTime required to return an answerUseful only beside correctness
Average bid per 1,000Relative benchmark cost indicatorNot an official price

Correctness deserves the most weight. A provider can return an answer for every task and still produce many invalid results.

Two rows make that clear. CapSolver returned answers for 100% of Amazon captcha solving tasks, but only 44% were correct. CapMonster Cloud reached 88% correctness on Arkose/FunCaptcha, yet returned an answer for only 46% of submitted tasks.

Not every provider appears in every category. A missing row means that comparable data was not available; it does not mean the service scored zero.

Overall ranking

The overall ranking combines the benchmark with coverage, API quality, SDK availability, public integration examples, and fallback handling.

RankServiceOverall assessment
12CaptchaBest balance of correctness, coverage, and integration support
2SolveCaptchaStrong AI-focused option with competitive benchmark results
3Anti-CaptchaBest on Turnstile and image captcha, but uneven elsewhere
4CapMonster CloudFast in selected categories, less consistent overall
5CapSolverVery fast, with weak correctness in some important tests
6DeathByCaptchaWeakest overall result in the available dataset

2Captcha did not win every category. It ranked first because it remained competitive across the available tests and offered the strongest integration package around those results.

SolveCaptcha was close on the published averages and won two categories. Anti-Captcha, CapMonster Cloud, and CapSolver were more specialized: each looked strong in some tests and much weaker in others.

2Captcha and SolveCaptcha captcha solving averages

The export includes averages across eight successful captcha types for these two services.

ServiceTypesAverage correctly solvedAverage receivedAverage time
2Captcha892.62%97.25%27.75 sec
SolveCaptcha892.50%97.62%27.16 sec

The gap is small. 2Captcha leads correctness by 0.12 percentage points. SolveCaptcha leads the received rate by 0.37 points and is 0.59 seconds faster on average.

These numbers are not enough to claim a statistical tie because the benchmark does not publish sample sizes or confidence intervals. They do show that benchmark performance alone does not clearly separate the two services. 2Captcha moves ahead when documentation, SDKs, public examples, coverage, and fallback handling are added to the evaluation.

Comparable averages are not available for the other four providers.

SolveCaptcha98%99%99%
CapSolver97%97%97%
CapMonster Cloud97%98%93%
Anti-Captcha45%45%47%

2Captcha held 99% across all three difficulty levels. SolveCaptcha matched it on moderate and easy tasks and trailed by one point on hard challenges. CapSolver stayed at 97% and was faster on hard and moderate tasks. Anti-Captcha was well behind the rest of the field.

reCAPTCHA v3

2Captcha97%99%19 sec
SolveCaptcha96%99%19 sec
CapMonster Cloud96%98%4.26 sec
CapSolver95%100%5.84 sec
Anti-Captcha94%100%17 sec

2Captcha posted the best correctness figure, but this was one of the closest categories. CapMonster Cloud and CapSolver were several times faster while staying within two percentage points of the leader. For a high-volume v3 workflow, that difference is worth testing rather than dismissing.

Amazon captcha

ServiceCorrectly solvedReceivedAverage time
2Captcha98%99%33 sec
SolveCaptcha98%99%33 sec
CapMonster Cloud96%97%17 sec
Anti-Captcha92%100%49 sec
CapSolver44%100%4.25 sec

2Captcha and SolveCaptcha were identical on all three metrics. CapMonster Cloud cut the response time roughly in half while giving up two points of correctness in captcha solving.

CapSolver was fastest and returned an answer for every task, but fewer than half of those answers were correct. This is the clearest example of why received rate and success rate cannot be treated as the same thing.

Arkose/FunCaptcha

ServiceCorrectly solvedReceivedAverage time
SolveCaptcha93%89%50 sec
2Captcha92%86%55 sec
CapMonster Cloud88%46%37 sec

SolveCaptcha led, although only narrowly: one point in correctness, three points in received rate, and five seconds in response time.

CapMonster Cloud answered faster, but more than half of submitted tasks produced no result. Its 88% correctness figure is misleading unless the 46% received rate is shown beside it.

Cloudflare Turnstile

ServiceCorrectly solvedReceivedAverage time
Anti-Captcha99%100%29 sec
CapMonster Cloud97%99%11 sec
2Captcha96%99%13 sec
CapSolver94%100%10 sec
SolveCaptcha94%99%14 sec

Anti-Captcha delivered the best quality result, but it was also the slowest service in the table. CapMonster Cloud offered a practical middle ground at 97% correctness and 11 seconds. Since all five providers remained between 94% and 99%, latency deserves more attention here than it does for Amazon or image captcha.

Cloudflare Captcha Solving Challenge

ServiceCorrectly solvedReceivedAverage time
SolveCaptcha97%100%14 sec
2Captcha95%100%14 sec

The services matched on received rate and response time, leaving the two-point correctness difference to decide the category in SolveCaptcha’s favor. No comparable rows were available for the other providers.

Image captcha solving

ServiceCorrectly solvedReceivedAverage time
Anti-Captcha71%99%15 sec
SolveCaptcha63%98%18 sec
2Captcha61%98%18 sec
CapMonster Cloud40%99%1.53 sec
CapSolver15%99%0.70 sec

Anti-Captcha led by a clear margin, though even its 71% result shows how difficult this category was for the whole field.

CapMonster Cloud and CapSolver answered almost immediately, but their correctness fell to 40% and 15%. At that point, response time says little about how quickly the surrounding workflow will actually finish.

When speed matters for captcha solving

Speed matters most when the accuracy gap is small. reCAPTCHA v3 is a good example: CapMonster Cloud and CapSolver were far faster than 2Captcha while trailing by only one or two points.

Amazon captcha shows the opposite pattern. CapSolver took 4.25 seconds but reached 44% correctness, compared with 98% for 2Captcha and SolveCaptcha. Repeating failed tasks can consume more browser time, proxy traffic, and worker capacity than the initial time saving is worth.

The useful production metrics are completed workflows per hour, retries per successful task, browser restarts, proxy traffic, and total completion time. Solver latency is only one part of that calculation.

Where each captcha solving service fits

2Captcha

The strongest general-purpose option in this dataset. It led reCAPTCHA v2 and v3, tied on Amazon captcha, stayed competitive elsewhere, and had the broadest integration support.

It makes the most sense for mixed workloads where maintaining several provider integrations would create more complexity than value.

SolveCaptcha

A close second overall, with wins on Arkose/FunCaptcha and Cloudflare Challenge. It also tied on Amazon captcha and placed ahead of 2Captcha on image captcha.

It is particularly relevant for AI-focused automation and workloads concentrated around the categories it won.

Anti-Captcha

The specialist choice for Turnstile and image captcha. Its results in those categories were the best in the benchmark, while its reCAPTCHA v2 performance was much weaker.

CapMonster Cloud Captcha Solving

Strong on reCAPTCHA v3, Turnstile, and Amazon captcha when speed matters. The low Arkose/FunCaptcha received rate and weak image captcha result make a broad recommendation difficult.

CapSolver

Fast across much of the benchmark and competitive on reCAPTCHA and Turnstile. Its Amazon and image captcha results were too weak to justify using the same configuration everywhere.

DeathByCaptcha

The service ranked sixth overall, but the export did not include detailed category rows. There is not enough data here for a more specific recommendation.

Choosing a captcha solving provider

puzzle showing captcha solving

Start with the captcha mix in the real workload. A Turnstile-heavy project will not produce the same shortlist as one built around reCAPTCHA v2 or Arkose/FunCaptcha.

Next, measure complete workflows rather than returned answers. Track accepted results, retries, browser restarts, proxy traffic, worker occupancy, and total completion time.

Integration quality also affects the final cost. Review task payloads, polling and callbacks, SDKs, proxy support, error handling, reporting, fallback behavior, and whether public examples are maintained.

This is a starting point, not a fixed routing plan. Results can change with the site, region, proxy quality, browser fingerprint, session state, integration method, and provider load.

FAQ

Is the fastest service always the best?

No. Speed becomes decisive when the correctness gap is small. When the faster service produces many more invalid answers, retries can erase the advantage.

Should teams use more than one captcha solving provider?

Sometimes. A multi-provider setup can improve mixed workloads and provide a fallback during quality drops or outages. It also adds integration, billing, monitoring, and maintenance work.

Does a benchmark guarantee the same result on a specific site?

No. Challenge settings, proxies, fingerprints, location, session state, and risk scoring can all change the outcome. A benchmark narrows the field; tests on the actual target determine the final choice.

Conclusion for Captcha Solving Services

2Captcha had the best overall balance, but it was not the best service in every category. SolveCaptcha and Anti-Captcha led several individual tests, while CapMonster Cloud and CapSolver offered useful speed advantages where their accuracy stayed close to the leaders.

The sensible approach is to shortlist providers by captcha type, test them on the real workflow, and judge them by completed tasks rather than response time alone.
