It’s a Ruby wrapper for the 2Captcha API, allowing developers to automate CAPTCHA solving (like image and reCAPTCHA v2/v3) in Ruby-based scripts or web scrapers.

The gem is published by [infosimples](https://github.com/infosimples/two_captcha), but it appears abandoned, with no major updates, low activity, and limited support for modern CAPTCHA types or Ruby versions.

Mostly yes, but it's limited to basic endpoints and doesn’t support all recent updates, features, or error handling improvements from the 2Captcha API.

 No. The gem has no built-in support for newer CAPTCHA types like hCaptcha, Funcaptcha, or Arkose Labs, and even reCAPTCHA support is basic and fragile**.

0/5, based on current feedback. Users report issues with outdated dependencies, unreliable responses, and lack of official support.

Yes. CaptchaAI uses the same API schema as 2Captcha, so you can replace your 2Captcha key with a CaptchaAI key in the same script for more reliable solves and better support.

CaptchaAI offers faster solve times, more reliable accuracy, and responsive support—especially for image-based CAPTCHAs and reCAPTCHA v2/v3, which 2Captcha often struggles with.

Simply, swap out the base API URL to `https://ocr.captchaai.com/in.php` and ensure you send the required parameters: `key`, `method`, and `body` (for base64 image CAPTCHAs) or `googlekey` and `pageurl` (for reCAPTCHA).

Not easily. The gem lacks built-in thread handling, and developers must implement their own queue management or async architecture.

Not without modification. The gem is outdated and unreliable. Using CaptchaAI with a custom Ruby wrapper or direct HTTP requests is a better long-term solution.
