What is Cloudflare Turnstile?
Cloudflare Turnstile is a free bot mitigation service offered by Cloudflare. It helps website owners protect their sites from threats like scraper bots, spam bots, and other automated attacks. Here are some key things to know about Cloudflare Turnstile:
- It uses JavaScript challenges to distinguish bots from real human visitors. These challenges test for JavaScript support and input capabilities that bots generally lack.
- When Turnstile detects a suspicious visitor, it will present a JavaScript-based captcha challenge to verify if the visitor is human. Legitimate humans can quickly solve the simple challenges, while bots cannot.
- As a Cloudflare service, Turnstile is easy to set up for any site using Cloudflare. Just enable it through the Cloudflare dashboard. No coding needed.
- It is completely free and works on top of your existing Cloudflare plan. It provides strong bot mitigation without upgrading your Cloudflare pricing tier.
- Turnstile is lightweight and prioritizes legitimate users. The JavaScript challenges aim to have as little impact on real visitors as possible.
- Provides dashboard visibility into threats blocked or verified by Turnstile, including trend data over time.
Overall, Cloudflare Turnstile gives site owners a free, easy-to-use bot mitigation option that works at high scale. With it, you can protect your site content and API resources from automated scraping without paying extra or burdening real users.
