Recognize is a Node.js library that integrates with RuCaptcha.com to automate solving of image-based CAPTCHAs. It's useful for developers who need a simple CAPTCHA-solving solution.

Yes, Recognize is open-source and free to use. However, using it requires an active API key from a CAPTCHA-solving provider such as RuCaptcha or CaptchaAI.

Out of the box, Recognize supports standard image CAPTCHAs. For other types like reCAPTCHA v2 or v3, additional customization is needed.

Yes, CaptchaAI is fully compatible with Recognize. You can use the same base64 submission flow by changing the API endpoint and payload format as per CaptchaAI’s documentation.

🔴 RuCaptcha sometimes returns unstable solve rates or delays during peak hours. CaptchaAI provides a more consistent infrastructure with higher thread limits, support for complex CAPTCHAs, and zero balance trial testing.

Replace the RuCaptcha endpoint (rucaptcha.com/in.php) with https://ocr.captchaai.com/in.php, and ensure you use the correct parameters:

• key: Your CaptchaAI API key
   
• method=base64
   
• body: Your base64 image
   

json=1: For JSON response

The default implementation parses text responses. If you switch to CaptchaAI, append json=1 to receive a structured JSON response (status and request).

RuCaptcha lacks some modern CAPTCHA support (e.g. FunCAPTCHA, reCAPTCHA Enterprise), and their API may throttle users during high demand. There's also limited support and a slower response to abuse or ticket issues.

Yes. CaptchaAI allows you to scale horizontally with multiple threads, and provides real-time usage statistics, optional proxy usage, and advanced CAPTCHA modules—ideal for power users.

Yes, always ensure your use complies with the site's terms of service. Automated CAPTCHA solving may be against the policies of the website you're interacting with.
