Overview

NordCaptcha is a privacy-first CAPTCHA. Visitors solve a lightweight challenge in a widget you embed; your server exchanges the resulting token for a verdict. No personal data is collected and tokens are single-use.

The flow is two steps:

  1. Embed the widget on any page with a form.
  2. Verify the token server-side using your secret key before trusting the request.

See the Integration guide for copy-paste snippets, and the FAQ for common questions.
