SOLVE uncaptcha (PHP / composer) SOFTWARE NOW WITH CAPTCHAAI
It’s an open-source PHP library that allows developers to solve different CAPTCHA types programmatically by integrating third-party solving services.
It supports ImageToText, reCAPTCHA V2, V2 Invisible, V3, FunCaptcha, GeeTest, HCaptcha, and Custom CAPTCHAs.
You can install it by running:
composer require topvisor/uncaptcha
No. You must configure it with a third-party CAPTCHA-solving service like CaptchaAI to handle actual solving requests.
Yes. CaptchaAI is officially supported and provides reliable support for image, reCAPTCHA V2/V3, and other types. Integration Guide
Many other solvers struggle with reliability, reCAPTCHA accuracy, or offer limited free trials. CaptchaAI provides a generous free tier, excellent OCR accuracy, and stable API support for PHP developers.
No. CaptchaAI does not support GeeTest or HCaptcha, even though uncaptcha supports them structurally. For those types, you’ll need to use a different service.
uncaptcha will return a failure response, and you can handle it with retries or fallback logic. Services like CaptchaAI return specific error codes like ERROR_CAPTCHA_UNSOLVABLE.
Yes, the PHP library itself is free and open-source. But the CAPTCHA-solving services (like CaptchaAI) may charge per solve after your free trial or credit runs out.
Simply update your provider configuration in PHP and use the CaptchaAI API key. Their API is compatible with uncaptcha’s expectations for major CAPTCHA types.
