Enable Turnstile (Cloudflare) for Gravity Forms


This is a great plugin which works on my website without any problem. Just install it, get the keys and drop the element on your form (drag and drop). Many thanks to the developer to provide this integration! This is the only plugin that really works. I used another plugin before but had some issues, e.g., submit button was disabled after pressing submit when required fields were missing, also, GeoIP-Location did not work when cloudflare turnstile was enabled, etc. Now, with this plugin, everything works! THANKS!


Works out of the box!

A lightweight plugin to enable Cloudflare's Turnstile alternative CAPTCHA on your Gravity Forms.
