- Today, we’re announcing the open beta of Turnstile, an invisible alternative to CAPTCHA. Anyone, anywhere on the Internet, who wants to replace CAPTCHA on their site will be able to call a simple API, without having to be a Cloudflare customer or sending traffic through the Cloudflare global network. Sign up here for free.
- Turnstile is our smart CAPTCHA alternative. It automatically chooses from a rotating suite of non-intrusive browser challenges based on telemetry and client behavior exhibited during a session. We talked in an earlier post about how we’ve used our Managed Challenge system to reduce our use of CAPTCHA by 91%. Now anyone can take advantage of this same technology to stop using CAPTCHA on their own site.
- While having to solve a CAPTCHA is a frustrating user experience, there is also a potential hidden tradeoff a website must make when using CAPTCHA. If you are a small site using CAPTCHA today, you essentially have one option: an 800 pound gorilla with 98% of the CAPTCHA market share. This tool is free to use, but in fact it has a privacy cost: you have to give your data to an ad sales company.
- According to security researchers, one of the signals that Google uses to decide if you are malicious is whether you have a Google cookie in your browser, and if you have this cookie, Google will give you a higher score. Google says they don’t use this information for ad targeting, but at the end of the day, Google is an ad sales company. Meanwhile, at Cloudflare, we make money when customers choose us to protect their websites and make their services run better. It's a simple, direct relationship that perfectly aligns our incentives.
