The end of the road for Cloudflare CAPTCHAs

The blog post discusses the reasons why CAPTCHAs are still widely used despite their poor user experience and presents an alternative solution called Cloudflare Managed Challenge. It explains that CAPTCHAs remain effective in differentiating humans from bots, but at a significant cost to usability. Many alternatives have been tried, but none have seen widespread adoption like CAPTCHA. The author then introduces the Cloudflare Managed Challenge platform, which tests multiple alternatives and adapts the challenge outcome based on individual visitor behavior. This approach has led to a 91% reduction in CAPTCHAs served by Cloudflare over the past year, with plans to reduce usage further. The post encourages users of the Cloudflare WAF to switch from "Legacy CAPTCHA" to Managed Challenge for better user experience and protection against bots.
