Turnstile API – John Graham-Cumming, Cloudflare
Cloudflare will launch Turnstile, a new API that any site owner can use to replace CAPTCHAs on their site, whether or not they use Cloudflare already. Turnstile is a smarter, invisible CAPTCHA alternative. The solution automatically chooses from a rotating suite of browser challenges that work behind the scenes, looking for signals there is a human user. With this technology, Cloudflare reduced their own use of CAPTCHA by 91%.
