A Ruby gem providing helper methods for integrating Google reCAPTCHA and hCaptcha into web applications.
Recaptcha is a Ruby gem that provides helper methods for integrating CAPTCHA services like Google reCAPTCHA and hCaptcha into Ruby web applications. It simplifies adding bot protection to forms by handling the frontend widget embedding and backend verification, supporting multiple CAPTCHA types including v2 Checkbox, v2 Invisible, and v3.
Ruby developers building web applications with Rails, Sinatra, or Rack who need to protect forms from spam and automated bot submissions.
Developers choose this gem for its straightforward integration, support for multiple CAPTCHA services and versions, and extensive customization options, reducing the complexity of implementing CAPTCHA protection in Ruby projects.

Supports all major reCAPTCHA versions (v2 Checkbox, v2 Invisible, v3) and hCaptcha, allowing flexible choice based on use case, as detailed in the README's API tables and key type matching.
Configurable for hCaptcha as a drop-in alternative to Google reCAPTCHA, with specific setup for verify_url and api_server_url, providing service independence in CAPTCHA selection.
Offers numerous options for themes, callbacks, script loading, and error handling, including enterprise key support and environment-specific configurations, as shown in helper method documentation.
Keeps CAPTCHA validation in controllers rather than models, adhering to Rails MVC principles and providing clean separation with helper methods like verify_recaptcha for form integration.
Handling multiple forms on a page, especially with invisible CAPTCHA, requires custom JavaScript callbacks and careful configuration, as admitted in the README's section on multiple forms and programmatic invocation.
Relies entirely on Google reCAPTCHA or hCaptcha APIs, introducing a single point of failure and potential network latency, with no built-in fallback mechanisms for API downtime.
Developers must ensure CAPTCHA keys match the specific type (e.g., v2 vs v3), and mismatches lead to errors like 'Invalid key type', complicating debugging and setup, as warned in the key obtaining section.
