Building secure websites: a guide to Cloudflare Pages and Turnstile Plugin

This tutorial demonstrates how to deploy a site on Cloudflare Pages and secure form submissions against bots using Cloudflare Turnstile, including explicitly rendering the widget, validating tokens server-side with the @cloudflare/pages-plugin-turnstile and the /siteverify API, and reviewing Turnstile analytics (Visitor/API Solve Rates and traffic) for bot detection insights. It also provides guidance on widget modes (managed, invisible), domain configuration, pre-clearance, and includes sample HTML/JS and a Pages Function handler.
