Moving from reCAPTCHA to hCaptcha

This post details the migration from Google's reCAPTCHA to hCaptcha for Cloudflare's CAPTCHA challenges. The rationale for the migration includes privacy concerns related to Google's data collection practices, blocking issues in certain regions (like China), and the introduction of charges for reCAPTCHA by Google. The post highlights the benefits of hCaptcha, including its privacy-focused data handling, comparable or better performance, accessibility features, support for Privacy Pass, and responsiveness. Cloudflare is leveraging its Workers platform to reduce hCaptcha's operational costs and has entered into a paid agreement with hCaptcha. The post also breaks down the usage of CAPTCHAs across different Cloudflare features, with Firewall and Bot Rules being the largest consumer, followed by IP Firewall and Security Level. It also mentions the use of CAPTCHAs by automated systems like Gatebot for DDoS mitigation.
