This library is designed to simplify integration with the RuCaptcha CAPTCHA-solving service in Go applications. It helps developers send CAPTCHAs, check task statuses, and retrieve results.

Yes. It supports image CAPTCHAs (via base64 or URL) and Google reCAPTCHA v2 and v3, depending on what RuCaptcha supports.

You can install it using:

bash

go get github.com/allush/go-rucaptha

Usage examples are provided in the GitHub repository to get you started quickly.

You’ll receive error messages like ERROR_CAPTCHA_UNSOLVABLE. You should implement retry logic or log/report these cases for review.

Yes, but note that RuCaptcha may have rate limits or performance bottlenecks at high volumes. Consider providers like CaptchaAI for scalable infrastructure.

Task timeouts due to slow response from RuCaptcha
 

• Receiving CAPCHA_NOT_READY too frequently
   
• Incomplete proxy or user-agent configuration for reCAPTCHA

RuCaptcha is widely used but occasionally suffers from low solve rates, especially during high load times. Developers seeking more consistent SLA-based solving often migrate to providers like CaptchaAI, which are tuned for higher success under load.

Not directly. This library is built for RuCaptcha’s API format. However, CaptchaAI provides similar API endpoints, and adapting the code is straightforward due to similar request structures. You can also use CaptchaAI’s official Go documentation:

CaptchaAI offers faster solving times, more consistent results, and better support for advanced CAPTCHA types. In contrast, RuCaptcha occasionally struggles with overload or CAPTCHA complexity, which can delay task resolution.

Yes, the library itself is free and open source. However, you must pay for CAPTCHA solving via RuCaptcha or any other provider you integrate (e.g., CaptchaAI, 2Captcha).
