2. Important factors when evaluating CAPTCHA solving services

When choosing a CAPTCHA service provider to integrate into your system, special attention should be paid to the following criteria:

2.1. Processing speed

The service's response speed in solving CAPTCHA types, from simple ones like plain text to more complex ones like reCAPTCHA or puzzle CAPTCHA. Also, evaluate its scalability and stability when dealing with multiple concurrent requests.

2.2. Accuracy

CAPTCHA success rate is key. Many providers promise 95–99% accuracy, especially with human assistance. We test accuracy and refund policies for recognition errors.

2.3. Stability and reliability

Continuous service availability, 24/7 API access, and quick recovery from high load. For example, AntiCaptcha claims to have maintained 99.99% uptime since 2007. We will analyze historical performance data and outages.

2.4. Documentation and technical support

The quality of the documentation, sample code, support community, and speed of response from the engineering team are all factors that cannot be overlooked. How easy it is to get started with the API, whether an SDK is available, and how quickly support is responded to are all factors to consider.

2.5. Convenient integration capabilities (SDK)

The presence of official libraries for many programming languages, webhook support, easy API integration with tools like Selenium/Puppeteer, and developer-friendly features are big pluses for the service provider.

3. Speed & Performance: Which CAPTCHA solving service is the fastest?

When choosing a CAPTCHA solving service, response speed is important, especially if you need to solve multiple CAPTCHAs in succession or simultaneously. For simple tasks like reading text from images, most services return results within 5–15 seconds. However, with more complex CAPTCHAs (Google reCAPTCHA, Arkose FunCaptcha…), the time can be extended 10–40 seconds, and in the worst case up to 1 minute.

Highlights of each service:

• SolveCaptcha Leading in speed thanks to neural network technology. Simple images take 3–5 seconds, reCAPTCHA v2 averages 4–5 seconds, can even reach 2 seconds under ideal conditions.

• 2Captcha and AntiCaptcha close behind, leveraging a large CAPTCHA solving community. Average time for reCAPTCHA is 10–20 seconds; sometimes 2Captcha is extremely fast in 1–3 seconds if the task is accepted immediately. AntiCaptcha is more consistent but usually takes 18–40 seconds.

• DeathByCaptcha (DBC) Slightly slower, reCAPTCHA takes around 15–35 seconds due to its heavy reliance on manual input. However, for text CAPTCHAs, DBC can process them in 5–10 seconds with OCR enabled.

Conclusion on speed: SolveCaptcha is still the fastest option, with 2Captcha and AntiCaptcha sharing second place, while DeathByCaptcha is a few seconds slower but still meets most automation needs.

4. Scalability and parallel processing

For high volume projects, evaluating the concurrency capabilities of a CAPTCHA service is an important factor.

• AntiCaptcha: No hard limit on the number of concurrent tasks. The backend system is optimized to process thousands of CAPTCHAs per minute.

• 2Captcha: No artificial limit, but all requests are put into a common queue. When handling hundreds of tasks at the same time, response time may increase slightly. Thanks to its large staff base, 2Captcha maintains stable performance during peak hours.

• SolveCaptcha: Clearly disclose estimated throughput — up to 12,000 images/minute or approximately 11,000 reCAPTCHA v2/minute. If this is exceeded, the system will adjust queues or pricing.

• DeathByCaptcha (DBC): Can handle well, but at peak times often increase price by 10–20% to reduce load. For projects running hundreds of concurrent threads, DBC is less competitive than AntiCaptcha or SolveCaptcha.

5. Accuracy and reliability

All four services achieve 95–99% accuracy rates with human input, as confirmed by real-world testing. Errors are rare, but refund policies vary:

• 2Captcha, SolveCaptcha, DeathByCaptcha: Allows reporting of false results and automatic refunds.

• AntiCaptcha: There is no clear refund mechanism; errors are considered additional costs.

With new or complex CAPTCHAs, any service can struggle initially. However, established platforms like2Captcha and AntiCaptchaOften update processing faster, ensuring stable performance.

6. API stability and uptime

AntiCaptcha maintains impressive uptime rates 99,99% Since 2007, there have been only occasional major outages. 2Captcha has had almost no downtime, which has been mainly due to changes in the CAPTCHA provider, not infrastructure failures. DeathByCaptcha has been down from time to time, but has generally maintained stable performance. SolveCaptcha, despite being new to the market, has yet to record significant downtime due to its lightweight architecture and monitoring system 24/7.

Especially, because 2Captcha-like protocols have become the common standard, you can easily switch to another provider when needed. This is a safe backup solution for critical processes, ensuring continuous and efficient operations.
