Cloudflare’s Turnstile, developed by Cloudflare, serves as an innovative CAPTCHA alternative that can be incorporated into any website. It aims to be less intrusive and functions without redirecting traffic through Cloudflare or displaying a CAPTCHA to visitors.
Customers can choose from different widget types to incorporate Turnstile into their websites, either as visible or completely invisible widgets.
Turnstile provides multiple widget types:
- Non-interactive challenges.
- Non-intrusive interactive challenges (e.g., clicking a button) if the visitor is suspected to be a bot.
- Invisible challenges to the browser.
Turnstile is currently in an open beta stage and is available as a free tool for all customers. During the beta, customers are limited to 1 million calls per month to the siteverify verification endpoint per site. Customers needing more requests can upgrade to Enterprise Bot Management.

Comparing Turnstile and reCAPTCHA
- Developed by Cloudflare.
- Focuses on a less intrusive and user-friendly experience.
- Adapts challenges based on individual visitor/browser and avoids displaying visual puzzles.
- Integrates with WordPress and Drupal through plugins and modules.
- Developed by Google.
- Performs spam and bot detection through interactive challenges.
- Includes the “I am not a robot” checkbox and image selection puzzles for users.
- Well-known and widely adopted across different platforms.
- May occasionally require users to solve more complicated puzzles.
While both solutions provide robust protection against spam and bots, their approach and user experience differ. Turnstile aims for a seamless experience by minimizing or avoiding user interactions, whereas reCAPTCHA relies on interactive challenges for verification.
