Comparison of captcha solving services: updated data
A captcha solving service should not be selected by response speed alone. In production automation workflows, the more important factors are the share of correctly solved tasks, answer delivery stability, captcha type coverage, API quality, SDKs, error handling, and fallback processing for difficult cases.
This is an updated version of the article based on the new CaptchaTheCat data table. The numeric comparison covers 2Captcha, SolveCaptcha, CapSolver, CapMonster Cloud, and Anti-Captcha. DeathByCaptcha has been removed from the numeric comparison because the new table does not include rows for it.
Main conclusion: based on the updated metrics, 2Captcha remains the most balanced option overall. It does not lead in every individual category, but it shows the best average correctly solved % among services with full table coverage, the lowest average response time across its own rows, and stable results across reCAPTCHA v2, reCAPTCHA v3, Amazon WAF AWS captcha, Cloudflare Turnstile, and Cloudflare Challenge.
TL;DR
| Result | Service | Reason |
|---|---|---|
| Best overall balance | 2Captcha | 93.11% average correctly solved %, 97.22% received %, 9.36 sec average time across 9 categories |
| Strong AI solver | SolveCaptcha | 92.44% average correctly solved %, 97.67% received %, lower average bid than 2Captcha |
| Strong individual rows | CapSolver | 100% in reCAPTCHA v2 Moderate, Cloudflare Turnstile, and Amazon WAF AWS captcha, but smaller table coverage |
| Leader in image captcha | Anti-Captcha | 71% correctly solved % in Image / Picture |
| Fast answers in selected tasks | CapMonster Cloud | Strong rows in reCAPTCHA v2 Moderate, reCAPTCHA v2 Hard, Cloudflare Turnstile, and Amazon WAF AWS captcha |
What data is used
The updated table uses four main parameters:
| Parameter | What it means |
|---|---|
avg recognition time |
Average time to receive an answer |
received % |
Share of tasks where the service returned a result |
correctly solved % |
Share of correctly solved tasks |
avg bid / 1000 |
Price indicator per 1000 tasks within the research |
Important interpretation rule: a fast answer is not the same as a good result. If a service returns an incorrect solution, the automation workflow still breaks: the task has to be retried, the session may reset, retry volume increases, and error handling becomes more complex.
The evaluation order should be:
- First,
correctly solved %. - Then
received %. - Then average response time.
- Only after that,
avg bid / 1000.
Service summary
| Service | Categories in the table | Average correctly solved % | Average received % | Average time | Average avg bid / 1000 |
|---|---|---|---|---|---|
| 2Captcha | 9 | 93.11% | 97.22% | 9.36 sec | 2.08 |
| SolveCaptcha | 9 | 92.44% | 97.67% | 25.67 sec | 0.91 |
| CapSolver | 7 | 86.57% | 99.86% | 12.03 sec | 0.74 |
| CapMonster Cloud | 8 | 88.12% | 92.25% | 20.7 sec | 0.74 |
| Anti-Captcha | 7 | 70.14% | 99.43% | 43.86 sec | 1.80 |
The averages show that 2Captcha and SolveCaptcha remain close competitors, but with different strengths. 2Captcha has a higher average correctly solved % and is much faster on average. SolveCaptcha has a slightly higher received % and a lower average avg bid / 1000.
CapSolver looks stronger than in the previous version of the article in several individual categories: it reaches 100% correct in reCAPTCHA v2 Moderate, Cloudflare Turnstile, and Amazon WAF AWS captcha. But it does not cover every category in the table, and its Image / Picture result remains low at 15% correctly solved.
Results by captcha type

This table shows why a winner cannot be selected from one row. CapSolver is strong in Cloudflare Turnstile and Amazon WAF AWS captcha. Anti-Captcha leads in Image / Picture. SolveCaptcha is better than 2Captcha in Cloudflare Challenge and slightly higher in Image / Picture. But 2Captcha produces a more even result across all categories and more often remains in the leading group.

In the updated table, CapSolver should not be described simply as a fast but weak service. It has strong rows: 100% correct in reCAPTCHA v2 Moderate, Cloudflare Turnstile, and Amazon WAF AWS captcha. Its received rate is also high almost everywhere.
But the comparison with 2Captcha is still uneven. 2Captcha is higher by correctness and faster in reCAPTCHA v2 Easy, reCAPTCHA v2 Hard, and reCAPTCHA v3. In Image / Picture, the correctness gap is large: 61% for 2Captcha versus 15% for CapSolver. In Amazon WAF AWS captcha, correctness is equal at 100%, but 2Captcha is faster, while CapSolver has a higher received rate.
Main conclusion: CapSolver is strong in selected categories, especially Turnstile and Amazon WAF AWS captcha, but 2Captcha looks more universal across the full table.
SolveCaptcha and CapSolver: coverage versus strong individual rows

Pros and limitations of the services
| Service | Pros | Limitations |
|---|---|---|
| 2Captcha | Best overall balance in the updated table; 93.11% average correct; 9.36 sec average time; strong results in reCAPTCHA v2, reCAPTCHA v3, Amazon WAF AWS captcha, and Cloudflare Turnstile; API, SDKs, GitHub resources, and fallback processing for complex tasks | Not the correctness leader in Image / Picture, Cloudflare Challenge, or Cloudflare Turnstile; average bid is higher than SolveCaptcha |
| SolveCaptcha | Strong AI solver; 92.44% average correct; 97.67% received; lower average bid than 2Captcha; beats 2Captcha in Cloudflare Challenge and Image / Picture | Slower than 2Captcha across most shared categories; lower by correctness in reCAPTCHA v3, Amazon WAF AWS captcha, and Cloudflare Turnstile |
| CapSolver | 100% correct in reCAPTCHA v2 Moderate, Cloudflare Turnstile, and Amazon WAF AWS captcha; high received rate; strong selected WAF/token scenarios | No rows for Cloudflare Challenge or Arkose / FunCaptcha; low correctness in Image / Picture; average correctness is below 2Captcha and SolveCaptcha |
| CapMonster Cloud | Strong rows in reCAPTCHA v2 Moderate, reCAPTCHA v2 Hard, Cloudflare Turnstile, and Amazon WAF AWS captcha; fast answers in some tasks | Lower average received rate; no Cloudflare Challenge row; weaker in Image / Picture |
| Anti-Captcha | Best correctness in Image / Picture; strong result in Cloudflare Turnstile and Amazon WAF AWS captcha | Very weak rows in reCAPTCHA v2; high average response time; no rows for Cloudflare Challenge or Arkose / FunCaptcha |
Why 2Captcha wins the overall comparison
2Captcha does not win because it ranks first in every category. In the updated table, several categories are better for other services:
- Anti-Captcha leads in Image / Picture.
- CapSolver leads in Cloudflare Turnstile.
- SolveCaptcha leads in Cloudflare Challenge.
- CapSolver reaches 100% in reCAPTCHA v2 Moderate and Amazon WAF AWS captcha.
But across the full table, 2Captcha provides the most even set of metrics:
- 9 out of 9 categories in the updated table;
- 93.11% average
correctly solved %; - 97.22% average
received %; - 9.36 seconds average response time;
- strong results in reCAPTCHA v2, reCAPTCHA v3, Amazon WAF AWS captcha, and Cloudflare Turnstile;
- clear integration base: API, SDKs, GitHub resources, callbacks, and fallback processing for difficult tasks.
For production automation, this is more important than winning one isolated row. A working service should not only return an answer quickly, but also handle different captcha types consistently inside longer workflows: browser automation, data collection, QA processes, account operations, or WAF-protected environments.
An AI service does not have to be AI-only
Comparisons of captcha solving services often use a crude frame: either a service is fully automated, or it is “not AI”. For production use, that frame is not helpful.
AI recognition works well on common high-volume tasks. But real workflows include non-standard interfaces, complex visual checks, behavioral signals, WAF checks, and tasks where the result depends on session state. In these cases, fallback processing does not contradict an AI-based approach. It increases stability where a single automated layer may fail.
SolveCaptcha can be correctly described as an AI solver for captcha processing: the service focuses on automated recognition and shows strong results in popular captcha types. But 2Captcha remains the more balanced solution for different automation scenarios because it combines quality, speed, coverage, and integration capabilities.
How to evaluate a service before integration
Before connecting a captcha solving service, check concrete operating parameters instead of broad marketing claims:
- Which captcha types appear in your workflow.
- What
correctly solved %the service shows for those exact types. - How stable its
received %is. - What the actual response time is in your workflow.
- Whether the API fits your integration.
- Whether SDKs, GitHub examples, callbacks, a test environment, and a status page are available.
- Whether difficult tasks can be routed to fallback processing.
- Whether the price indicator still makes sense after correctness and received rate are checked.
If you need a universal service for automation, 2Captcha looks like the best option in this comparison. It combines high average correctness, good received rate, low average response time, support for different captcha types, API, SDKs, GitHub resources, and fallback processing for difficult cases.
