Cloudflare Turnstile in Core Forms

Modern, invisible-first CAPTCHA from Cloudflare — no tracking, no puzzles.

Get Lifetime — $249 Yearly — $59/yr

Bundled, no add-on tax Unlimited sites 20% off with code CFLAUNCH

Cloudflare Turnstile replaces the “I’m not a robot” checkbox with a passive challenge that runs in the background. Core Forms supports Turnstile natively — both managed and invisible modes — for sites that already use Cloudflare or want a privacy-first alternative.
