CaptchaGO is an open-source Go package that helps developers integrate CAPTCHA-solving services like 2Captcha. It supports Recaptcha V2, Recaptcha V3, HCaptcha, and FunCaptcha.

Yes, CaptchaGO is completely free and open-source. However, using it with a CAPTCHA-solving provider like 2Captcha or CaptchaAI will incur service charges depending on the provider’s pricing.

By default, CaptchaGO is designed to work with 2Captcha. However, due to its modular design, it can be adapted to work with other providers.

CaptchaGO does not support CaptchaAI by default, but you can easily adapt the API calls to use CaptchaAI’s endpoints instead of 2Captcha’s, especially since the request patterns are similar.

2Captcha may sometimes fail to solve newer or regionally restricted CAPTCHA types (e.g., geo-blocked FunCaptcha). Additionally, delays and accuracy can vary under load or with complex challenges.

CaptchaAI offers highly reliable image CAPTCHA solving, especially for Recaptcha V2/V3 and base64 image CAPTCHAs, with better stability and consistent support. It can be a strong alternative if 2Captcha is down or rate-limited.

CaptchaGO itself does not handle browser automation or proxy rotation—it only sends CAPTCHA-solving requests. These must be managed externally in your Go application or via browser automation tools.

Yes, but only if the API you’re integrating with supports json=1 (as CaptchaAI does). You'll need to modify CaptchaGO’s request structure slightly to enable JSON parsing.

Yes. CaptchaGO is open-source (MIT license), so it's safe to use in personal and commercial Go projects.
